Type: Suggestion, Component: BIOSINT API (1 item(s)) 


Type: Suggestion 

Component: BIOSINT API 

Category: Function BIOS_Install_Error_Handler 

Synopsis: Should return the old error handler vector. 

Description: When the function was called, it should return the vector of the error handler which was 

installed before. 

Fix: Changed API and BIOS_Install_Error_Handler() function 

Type: Suggestion, Component: Fossil API (1 item(s)) 



Component: Fossil API 

Category: Callback function 

Synopsis: Implement events for error handling and 9th data bit handling. 

Description: The fossil callback function should be additional called on parity error, framing error, 

long/short break and ninth databit receiving. The event-parameter of the callback function 

should denote the cause of the call. 

Fix: Add two new events FE_ERROR_DETECTED and FE_DATA_AVAIL9. In case of 

FE_ERROR_DETECTED the data buffer holds status information and the received 

character.

Type: Suggestion, Component: HWAPI (1 item(s)) 



Component: HWAPI 

Category: Int not supported - message 

Synopsis: Suppress the int not supported - message for interrupt 67h. 

Description: The Int not supported - message should be suppressed for the interrupt 67h since this 

interrupt number is used by dynamic linking service. 

Fix: Warning is suppressed now. 

Type: Suggestion, Component: PPP (2 item(s)) 




Category: PPP client 

Synopsis: Modem control 

Description: The PPP client doesn't recognize, if a modem connection breaks. Should add a modem 

control feature similiar to PPPserver. 

Fix: Implemented 





Synopsis: Cyclic modem control 

Description: The current implemented modem control of the PPP client and server is only executed, if 

there are no data received during the defined time interval. It should be possible to 

execute the control commands always after the time interval. 

Fix: Implemented. 

Type: Suggestion, Component: TCPIP API (1 item(s)) 



Component: TCPIP API 

Category: Socket options

Release Notes SC11 @CHIP-RTOS V1.25 Beta 



Type: Defect 


Category: Path length 

Synopsis: Creating a deep directory structure leeds to stack overflow 

Description: If one creates an as deep as possible directory structure (a:\x\x\x\x\x\...\x\), the stack of the 

main task overflows. 

Fix: Fixed 


Type: Defect 


Category: Rename command 

Synopsis: Rename should not be permitted if file or directory is in use 

Description: Rename WEB directory to WEB1 on SC1x3 and observe that DIR command then 

indicates "WEB1 (WEB)" for this directories new name. System becomes confused. 

Fix: Prevent name changed when a file system object is in use (e.g. when a directory is used 

as a "Current Working Directory" by some task.) 

Type: Defect, Component: Int21h (1 item(s)) 


Type: Defect 

Component: Int21h 

Category: Function 0x68 

Synopsis: Function doesn't work 

Description: The function always returns error code 2 (Invalid handle). 

Fix: Fixed 

Type: Defect, Component: RTOS API (1 item(s)) 


Type: Defect 

Component: RTOS API 

Category: Wait on Events 

Synopsis: Negative timeout argument , used for polling events, should return error code -27 for 

timeout if events not ready. 

Description: Currently a polling with negative timeout parameter returns -48 (= INVALID TIME ARG) if 

no event is ready. 

Fix: Correct Event Wait function in RTOS 



Type: Defect 


Category: DHCP client 

Synopsis: Gateway option 

Description: At the following situation the SC1x DHCP client works not correct: The DHCP client has 

received a valid gateway ip address from the DHCP server and set it as its default 

gateway. 

Because of a possible configuration change of the DHCP servers configuration, the DHCP 

server no longer offers at further DHCP requests (e.g. forced by shell command ipeth) a 

gateway address to the SC1x client. In that case, the SC1x wrongly still accepts the old 

gateway address, instead of erasing it. 

Fix: Fixed 


Type: Defect


Category: TCP sockets 

Synopsis: Equal source and destination port numbers 

Description: It is not possible to establish TCP connections with equal source and destination port 

numbers. 

Bug exists since SC1x RTOS V1.20 and SC1x3 RTOS V1.05. 

Fix: Fixed. 

Type: Defect, Component: Webserver (1 item(s)) 


Type: Defect 


Category: Vulnerability 

Synopsis: If an illegal "if-modified" format line is given by the browser, the IPC@CHIP webserver can 

crash. 

Description: A internal buffer overflow can lead to an invalid opcode. 

Fix: Fixed. 

Type: Suggestion, Component: @CHIP-RTOS (3 item(s)) 



Component: @CHIP-RTOS 

Category: Memory manager 

Synopsis: Should add an API function that allows the user to set the owner of a memory block. 

Description: This is useful if a demon task creates several threads that work independent from the 

demon. The demon can allocate the stack memory for the new thread and assign this 

memory block to the task ID of this new thread. So the stack object will be automatically 

freed if the new thread terminates. 

Fix: Added helper_assign_mem() API 




Category: Internal servers 

Synopsis: Should add CHIP.INI PRIO switches to all internal server configurations. 

Description: For convenience it should be possible to configure the task priorities of all internal servers 

with a PRIO switch in CHIP.INI configuration. 





Category: TCP/IP Memory 

Synopsis: Should improve internal TCP/IP heap memory management. 

Description: Should revise the internal TCP/IP heap memory management and improve the recycling of 

TCP/IP internal memory blocks. This should reduce out-of-memory situations (TCP/IP 

stack reached memory limit). 


Type: Suggestion, Component: Command shell (2 item(s)) 



Component: Command shell 

Category: Format command 

Synopsis: Should add a quiet mode to the format command, that skips the confirmation check. 

Description: This would allow to call the format command with the BIOS_Execute() API function. 

Fix: Add option /Q to format command syntax. 



Component: Command Shell 

Category: Format command

Synopsis: The disk format operation should include a read-back and verify action. 

Description: Currently the written data is not verified on the media. The format procedure should 

include a read back and verify. Due to the insigificant additional amount of time required to 

read the media following an often time consuming block write operation, this verify action 

has been built into the FORMAT command instead of being provided as a command line 

option. 

Fix: Fixed. 

Type: Suggestion, Component: FTP server (3 item(s)) 



Component: FTP server 

Category: CWD command 

Synopsis: A leading slash within the CWD path should be accepted. 

Description: This should increase FTP compatibility with some FTP clients, e.g. the Wget command 

line tool uses this syntax. 




Component: FTP Server 

Category: Virtual rootdir 

Synopsis: A leading slash inside of FTP commands is always interpreted as the root directory of the 

drive. 

Description: If a CHIP.INI entry is present that defines a user ROOTDIRx, then FTP commands with a 

leading slash, e.g. 'get /test.dat', are not accepted, because the access to this location is 

not allowed. 

Instead of this behaviour the leading slash should be interpreted as the specified root 

directory. 





Category: Rename command 

Synopsis: The rename command should tolerate command strings with leading slashs, followed by a 

drive letter. 

Description: This will help to increase compatibility to FTP clients, like CuteFTP. 


Type: Suggestion, Component: I2C API (2 item(s)) 



Component: I2C API 

Category: Timeouts 

Synopsis: The I2C timeout value should be configurable. 

Description: The timeout value should be adjustable by an API function. 





Category: Broadcast 

Synopsis: Should allow the general call address (0h) in I2C master mode. 

Description: Currently sending/receiving to/from the general call address (broadcast address) is not 

supported. 


Type: Suggestion, Component: Int21h (2 item(s)) 



Component: Int21h

Category: Get disk free space 

Synopsis: DOS function 0x36 delivers not always useful information for big disk sizes. 

Description: By design the standard DOS function 0x36 reports the number of clusters in a 16 bit value. 

Depending on the actual cluster size, bigger drives may be reported with wrong total/free 

size, because the number of clusters reaches the value 0xFFFF. 

Should implement a new functions that reports the "Total Disk Space" and "Free Disk 

Space" correctly. 

Fix: Add BIOS interrupt 0xA0 service 0x0A to report 32 bit cluster counts 

Add BIOS_Disk_Info() and BIOS_Disk_Space() API to C-Library as wrappers for this new 

BIOS API. 




Category: Function 0x0E (set default drive) 

Synopsis: Function 0x0E should return the total number of drives. 

Description: Currently the return value is undefined. 

Fix: Fixed. 





Category: Function 0x7B 

Synopsis: Additional parameter 

Description: The ARP user callback structure should be extended by an additional parameter 

devicehandle pointer. This allows the user to detect the source device of the incoming 

ARP packet for filtering. 





Category: Socket Interface 

Synopsis: Should add the socket select() API call. 

Description: The select() function allows a more efficient way to handle events on multiple sockets. 

Fix: Add C-Library select() and select_ms() API. 

Type: Suggestion, Component: TCPIP stack (1 item(s)) 




Category: Auto IP 

Synopsis: Enable auto IP by default 

Description: The AutoIP feature should be enabled by default. 






Category: Performance 

Synopsis: Speed up webserver 

Description: Since last RTOS version the webserver transfer rate is decrased. It should be as fast as 

with the RTOS versions before. 

Fix: Fixed. 

Total: 23 Top

Release Notes SC11 @CHIP-RTOS V1.21 

Type: Defect, Component: C-Library (1 item(s)) 


Type: Defect 

Component: C-Library 

Category: Build process 

Synopsis: Floating-point example does not work with Paradigm built C-Lib 

Description: _NVRAM section added by Paradigm compiler to OBJ records causes 

_STACK segment to be appended to data segment. This causes the stack 

based Floating-Point Emulator to not work. 

Fix: Provide two versions of Beck C-Libraries, one for BC5 and another for 

Paradigm-Beck compiler. 

Fixed with CLIB V2.07. 

Type: Defect, Component: CHIP.INI (1 item(s)) 


Type: Defect 

Component: CHIP.INI 

Category: BIOS_Set_Ini_String() API 

Synopsis: Setting an item that was blank does not work correctly 

Description: [DEVICE] 

NAME= 

entry will be set to ... 

NAME= 

THE_ENTERED_NAME 

Where the item value ends up on subsequent line. 

Fix: Fixed. 

Type: Defect, Component: FTP Server (2 item(s)) 


Type: Defect 

Component: FTP Server 

Category: GET command 

Synopsis: GET command with nonexistent file delivers no error message. 

Description: In this case the SC1x delivers garbage data in an endless loop. 

Fix: Fixed. 


Type: Defect 


Category: RMD command / LIST command 

Synopsis: Should fix RMD and LIST commands. 

Description: The RMD command should tolerate a slash as last char. The FileZilla FTP 

client uses this. 

On Sc1x3 the LIST command sometimes delivers garbage for the size of a 

directory. The file size of a directory should always be zero. 

Fix: Fixed

Type: Defect, Component: HWAPI (1 item(s)) 


Type: Defect 


Category: Hal function 0x84 

Synopsis: Install powerfail interrupt function 

Description: It is not possible to install an user interrupt service function on the powerfail 

interrupt. 

Fix: Fixed 

Type: Defect, Component: I2C API (1 item(s)) 


Type: Defect 


Category: I2C_restart function 

Synopsis: I2C_restart() does not work correct. 

Description: After a I2C_restart() the I2C address is not retransmitted on the next 

transmit/receive call. 

Fix: Fixed. 

Type: Defect, Component: Int21h (1 item(s)) 


Type: Defect 



Synopsis: Function doesn't work 

Description: The function always returns error code 2 (Invalid handle). 

Fix: Fixed 

Type: Defect, Component: RTOS (1 item(s)) 


Type: Defect 

Component: RTOS 

Category: CPU core 

Synopsis: Make workarounds for CPU instructions (CLI, MOV SS, POP SS). 

Description: There are two CPU core problems that need a workaround inside the RTOS. 

1) CLI sometimes does not take immediate affect for SC1x3 or SC13/SC11 

CPU's. 

This depends on code alignment, which can't be controlled. 

2) MOV SS and POP SS don't mask the interrupts for this and the next 

instruction (load of SP). 

So an interrupt can possibly work on an invalid stack, which will lead to 

corrupted memory. 

Note: The SC12 does not have these problems. 

Fix: Place a NOP after the CLI, or otherwise position the CLI in advance by one 

instruction of where it must become affective. Mask NMI around stack switch 

operations. 

Note: 

The Paradigm compiler (7.00.026 and before) uses SS inside the 

malloc()/free() functions. This has been fixed with build 7.00.027 of the 

compiler.

For masking/unmasking the interrupts, please use the compiler macros 

enable/disable. They have been adapted to pay attention to the CLI 

instruction problem. 

Borland users should use the patched libraries and include files that Beck will 

offer. 



Type: Defect 


Category: Webserver and FTP server 

Synopsis: Possible deadlock 

Description: It could lead to a temporary (about 60 seconds) blockade of TCP/IP 

communication, if the task priority of the FTP server is beneath the 

webservers priority due to a change of the user. By default the FTP server 

has equal (internal higher) priority than the webserver. 

Fix: Fixed. 

Type: Defect, Component: UDP config server (1 item(s)) 


Type: Defect 

Component: UDP config server 

Category: User callback 

Synopsis: The response message is one byte larger than the user requested. 

Description: The last character in the UDP callback response message is garbage. 

Fix: Fixed. 



Type: Defect 


Category: HTTP requests 

Synopsis: HTTP 404 not found message not sent 

Description: If a requested URL doesn't exists, the Webserver returns wrongly the HTTP 

response code "200 OK" instead of "404 Not found". 

Fix: Fixed 


Type: Defect 


Category: If-Modified feature 

Synopsis: Buffer overrun 

Description: Noticed, when using MS Internet Explorer 7.0: A buffer overrun occurs, if the 

length of the browsers If-Modified statement exceeds 32 characters. The 

SC1x webserver doesn't check the exceeded size correctly. 

Fix: Fixed 

Type: Suggestion, Component: Command Shell (1 item(s)) 


Type: Suggestion

Component: Command Shell 

Category: DIR command 

Synopsis: Show file attributes in DIR output 

Description: The DIR command should display the file's attributes. 

Fix: Added ARS indicators to DIR command listing for "Archive", "Read-only" and 

"System" file attributes. 

Type: Suggestion, Component: CRYPT LIB (1 item(s)) 



Component: CRYPT LIB 

Category: Encryption 

Synopsis: Should increase speed of hash and encryption functions. 

Description: Encryption and hash functions should be made significantly smaller and 

faster. 

SC1x: Use assembly language support for MD5. 

SC1x3: Use assembly language support for MD5, DES, SHA1 and AES. 


Type: Suggestion, Component: HWAPI (1 item(s)) 




Category: Non-volatile data 

Synopsis: The user should be able to measure the time of all powerfail actions. 

Description: Should add the possibility to measure also the time that is needed to close 

the filesystem after the user non-volatile data is written. 

Fix: Implemented. User can now install a callback function, which is called when 

all powerfail actions are done. 

Type: Suggestion, Component: I2C API (1 item(s)) 




Category: Transmit/Receive Block Functions 

Synopsis: Should optimize speed of I2C block functions and further improve timeout 

handling. 

Description: Should reduce gaps between transmitted/received chars. 


Type: Suggestion, Component: Ping API (1 item(s)) 



Component: Ping API 

Category: Data size 

Synopsis: Max. Ping size 

Description: The current data size of ICMP Ping request is limited by 1024 byte. This size 

should be increased to 2080 bytes. This is the max. value of accepted 

incoming ping requests. 

Fix: Implemented.





Category: Webserver timeout 

Synopsis: Large Webserver timeout 

Description: The default TCP socket option TCP_MAXRT is set to 75 seconds. At high 

number of incoming HTTP requests, this can lead to webserver inactivity, until 

TCP/IP frees the used sockets after the timeout. 

Fix: Reduced timeout to 10 seconds. 

Type: New, Component: TCPIP API (1 item(s)) 


Type: New 


Category: IP Multicast 

Synopsis: Add sendto_iface() API call 

Description: It is neccessary to add an "send to interface" function for sending UDP 

Mulitcast packets over additional device interfaces (e..g. WLAN). At the 

moment sending of multicast packets works only via default ethernet. 


Total: 19 Top 


Type: Defect, Component: BIOSINT API (1 item(s)) 


Type: Defect 


Category: iniPutString() 

Synopsis: iniPutString() adds a section a second time under some conditions 

Description: 1) If file ends with an empty [SECTION], then iniPutString() adds this section 

a second time. 

2) If file ends with out a final CR-LF, then iniPutString() adds the section a 

second time. 

Fix: Fixed 



Type: Defect 


Category: DEL command 

Synopsis: DEL command should not delete READ-ONLY files 

Description: Original SC12 V1.01B does not delete READ-ONLY files, so neither should 

current RTOS. 

Fix: Fixed 

Type: Defect, Component: HW API (2 item(s))


Type: Defect 

Component: HW API 

Category: PIOs 

Synopsis: When switching a PIO between the various states, there can be a short 

period in which the pin is in an unwanted "Normal" or "Output state". 

Description: Calling the shell commands "PIO 17 4" followed by "PIO 17 2" on SC1x3 

leads to a reboot. 

During the state transition between "Output" and "Input" the PIO is in his 

"Normal" state for a short time. Because the "Normal" function of PIO17 is 

HOLD, this leads to a watchdog reset. 

Fix: Fixed 


Type: Defect 


Category: Watchdog 

Synopsis: The watchdog is sometimes triggered by the RTOS, although the watchdog 

mode is set to USER mode. 

Description: If watchdog mode is set to USER mode, the RTOS still triggers the watchdog 

inside some code areas, e.g.. the flash write function or when a serial port 

uses RS485 mode. 

Fix: Fixed. Do this additional watchdog triggering only when the watchdog mode is 

set to RTOS mode. 

Type: Defect, Component: TCPIP API (2 item(s)) 


Type: Defect 


Category: Set interface MTU 

Synopsis: User device handle is taken from wrong registers 

Description: The C-Lib SetIfaceMTU() function passes the userIfaceHandle parameter in 

registers ES:DI which matches the @Chip-RTOS HTML documentation for 

this API. However, the SWI function was using registers DX:SI. 

Fix: Fixed 


Type: Defect 


Category: Ping statistic function 0x77 

Synopsis: Close ping 

Description: Ping_Statistics closes the internal ping socket, if the max. number of 

transmitted packets is reached. Because of this behaviour mostly the last 

incoming ping reply gets lost. 

Fix: Fixed 



Type: Defect 


Category: TCPIP memory leak 

Synopsis: Fragmented IP packets

Description: Large number of fragmented IP packets can lead to tcpip memory leaks. 

Fix: Fixed 


Type: Defect 


Category: Memory management 

Synopsis: Memory demand 

Description: In rare cases TCPIP stack reaches very fast its memory limit. This happens in 

networks with very high rate of fragmened ip packets or at non-listening UDP 

connections 

Fix: Fixed 

Type: Defect, Component: TELNET (1 item(s)) 


Type: Defect 

Component: TELNET 

Category: console printf 

Synopsis: Telnet is too slow since rewrite of RTOS internal vsprintf() 

Description: One TCP/IP message is required for each character in some cases within the 

vsprintf(). This results in unacceptable TELNET performance, particularly on 

10Mbit SC12. 

Fix: Fixed. Prevent single character TELNET transmissions. 

Type: Defect, Component: TFTP server (1 item(s)) 


Type: Defect 

Component: TFTP server 

Category: Read files 

Synopsis: Read files 

Description: A file transfer from the IPC@CHIP to the requesting host will fail, if the filesize 

is a multiple of 512. 

Fix: Fixed 



Type: Defect 


Category: Memory allocation 

Synopsis: Memory allocation 

Description: The SC1x Webserver does allocate additional memory from the 

@CHIP-RTOS memory, if the fixed limit of 4 incoming requests is reached. At 

systems with low memory resources, the memory allocation will fail. 

Also it could lead to a tcpip memory overflow, if a very high number requests 

runs simultaneously. 

It was not intended to allow the addtional allocation. This must be removed 

from the webserver. 

Fix: Fixed 


Type: Defect


Category: Sockets 

Synopsis: Unclosed sockets 

Description: At very high rate of http requests sockets can stay open. 

It is necessary to set the Keepalive-check option for the webserver sockets. 

Fix: Webserver are now initiated with the Keep-alive option. 





Category: Default date 

Synopsis: The default date should be consistent over RTOS updates. 

Description: Currently the date initilization changes with every new RTOS version. 

Fix: Set date to 01.01.2006 




Category: Copy Protection Example 

Synopsis: There should be a short example available, which demonstrates how to 

protect an application form copy to another IPC@CHIP. 

Description: Use MD5 hash functions for simple copy protection. 

Fix: Implemented MD5 API. 

Type: Suggestion, Component: Chip.ini (1 item(s)) 



Component: Chip.ini 

Category: Delete chip.ini entries 

Synopsis: It should be possible to delete a complete CHIP.INI item line. 

Description: When passing a NULL pointer to the item value of the "CHIP.INI insert 

function", 

the item line is now deleted. 


Type: Suggestion, Component: Filesystem (4 item(s)) 




Category: FindFirst/FindNext 

Synopsis: Modify DIR command syntax 

Description: "DIR directory name" command on SC1x does not list the contents of the 

specified directory 





Category: DIR command

Synopsis: Current directory headline 

Description: Before listing all files, the DIR command should print a headline with the 

current directory name. E.g. If current == a:\tmp , the DIR command should 

print "Directory listing of a:\tmp". 





Category: Hotpluggable Drives 

Synopsis: Add new API functions to better support hotpluggable drives. 

Description: Add new API functions to install/remove a callback function for the events 

"drive is installed" and "drive is removed". 





Category: RTX_Access_Filesystem() API 

Synopsis: File system usage from tasks can be made easier 

Description: Requiring tasks to use the RTX_Access_Filesystem() API should not be 

necessary 






Category: SWI 0x21 Service 0x31: Keep Process 

Synopsis: Remove task. 

Description: The "Terminate and Stay Resident" action should delete the RTOS task to 

reduce the RTX resource usage. 

Fix: Redesign DOS SW 0x21 service 0x31 so that memory is resized after task is 

terminated and memory allocated to task is tagged as reserved for TSR. 

Type: Suggestion, Component: RTOS API (1 item(s)) 




Category: Task Priority 

Synopsis: A RTX_Get_Priority() API would be helpful in applications 

Description: This will allow utility functions in applications to raise priority and then restore 

it back to what it was without knowing the specifics of which thread it is 

operating on. 

Fix: Add Change_Priority() function which read out and/or writes priority 





Category: SNMP RTOS Version

Synopsis: Include SNMP feature in standard RTOS versions. 

Description: The SNMP feature should be included in the SMALL, MEDIUM, 

MEDIUM_PPP, LARGE and LARGE_PPP RTOS versions. 

Fix: Additional special SNMP RTOS versions are no longer provided. 





Category: Argument length 

Synopsis: Limited argument length 

Description: The argument length of an HTTP POST request is limited on SC1x by 768 

bytes. The size of the argument buffer should be configurable by a chip.ini 

entry. Newer WAP applications will also cause problems, because of their 

very large "Accept" messages inside of the http request. 

Fix: Implemented new CHIP.INI entries 

- HEADER_SIZE (SC1x3 only) 

- HEADER_REJECT (SC1x3 only) 

- POST_SIZE (SC1x only) 

At SC1x RTOS very large (and unused) "Accept messages" are filtered out by 

the webserver. 

Type: New, Component: Fossil API (1 item(s)) 


Type: New 


Category: Force RTS / Read CTS 

Synopsis: Add new functions for reading CTS and forcing RTS. 

Description: Because the serial ports 0 and 1 on SC1x3 have no PIO function for CTS and 

RTS, this new functions are needed. 

Fix: Implemented new fossil functions 0x86 and 0x87. 

Type: New, Component: TCPIP stack (2 item(s)) 


Type: New 


Category: Auto IP 

Synopsis: Implementation of Auto IP 

Description: Implementation of Auto IP. At the current @CHIP-RTOS a host assigns 

automatically IP address 1.1.1.1, if the IP address configuration failed. It 

would be better to replace this mechanism by the Auto IP protocol. 

Fix: Implemented CHIP.INI setting AUTOIP

Beck provides this version because of two important changes for IPC@CHIP SC11: 

1. This version takes care of the modified flash memory timing of the RoHS compliant SC11-LF. 

Older RTOS versions are not runnable at the SC11-LF. A downgrade is not possible. 

2. The new SC11 Bootloader (Version 2.30) locks up the upper 16 KBytes of flash memory. 

This area is now write-protected. Because of this behaviour, the flashdisk size is about 12KByte 

smaller than at earlier RTOS versions. The loss of flashdisk memory is compensated by code 

optimizations at the @CHIP-RTOS. 

For upgrading the IPC@CHIP targets, the CHIPTOOL version 5.9.2.1 or higher is required.

Type: New 


Category: Flashdisk 

Synopsis: Reduced flashdisk size 

Description: In comparision to SC11 version 1.00 and SC11 version 1.00, the flash disk 

size is about 12 KByte smaller. This change was necessary, because the new 

bootloader V2.30 locks up the highest 16 KByte of the flash memory. At 

earlier versions only the highest 4 KByte of Flash were reserved (but not 

write-protected) the flash disk area. Since bootloader V2.30 the highest 16 

KByte are write-protected. The loss of flashdisk memory is compensated by 

code optimizations at the @CHIP-RTOS.

Synopsis: Undefined maximum length of CGI pages 

Description: The maximum length of pages, produced by a users CGI function is 

undefined, because of the usage of non-normalized response buffer pointers 

inside of the @CHIP-RTOS. 

Fix: Fixed. The maximum allowed size of an CGI page is 65519 characters. If the 

size of page will go beyond this limit, the Webserver returns HTTP errorcode 

503. This errorcode is also returned, if memory allocation will fail, inside of the 

IPC@CHIP webserver. 


Type: Defect 


Category: CGI functions 0x07 and 0x08

Type: Suggestion, Component: UDP Config Server (1 item(s)) 



Component: UDP config server 

Category: Communication protocol 

Synopsis: Additional search key for identifying IPC@CHIPs at the network 

Description: Because of the new IPC@CHIP products the serial number is no longer a 

unique key for that purpose. E.g. it can happen, that a IPC@CHIP variant 

SC13 has the same serial number as a SC12. 

In that case, it is not possible to update the software of an IPC@CHIP over

TCP/IP UDP by using the serial number at the UDP config commands.The 

probability of such a conflict situation is very slight, but it is necessary to add 

a new identify method to the UDP config protocol. 

Fix: From now on, the worldwide unique 48bit MAC-Address of the internal 

ethernet controller can also be used at UDP config commands instead of the 

serial number. The old method (identify by serial number) is still supported, 

because of compatibility reasons. 

We will provide a new detailled description of the UDP config server protocol 

at our download page at the internet. The new extensions are used at our 

new CHIPTOOL release 4.0.1.8.
