task in some cases. 

Description: Other lower priority tasks will get no CPU time for a very long period. 

Or if the watchdog is set to user mode, this can lead to a reboot during SSL key exchange. 

Fix: Fixed and added a new API function SSL_HandshakeComplete() that can be called to wait for the 

SSL handshake to complete. 

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


Type: Defect 

Component: USB 

Category: Host Mode 

Synopsis: False USB_EVENT_ERROR_SOF_LOST event notified on attach.

Category: IPsec 

Synopsis: Move Internet Key Exchange (IKE) into a separate task 

Description: The IKE can require some significant amount of time during the modulo exponentation for Diffie- 

Hellmann key exchange. As delivered this action was in the device receiver thread (e.g. ETH0). 

It is undesireable to block the entire device input for these long calculations done for the device's 

IKE socket. So this action should be pushed down into background thread. 

Fix: Add IKE task. The task priority can be configured by a CHIP.INI entry.

@CHIP-RTOS. Bug exists only in SC1x3 RTOS 1.06Beta. 

Fix: Fixed. 

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


Type: Defect 

4 von 30

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


Type: Defect 

Component: TCPIP API 

Category: Device driver API

Type: Defect 



Synopsis: Repetition of NAKed CONTROL or BULK packets in hardware mighty lead to a dead-lock. 

Description: Packets on CONTROL or BULK pipes which the device answers with a NAK handshake are 

repeated in hardware. This may lead to a dead-lock of the controller, if the device keeps 

answering with NAK handshakes forever. No other packets can be transmitted. Packets NAKed 

by the device should be repeated in software. 

Fix: BULK or CONTROL packets NAKed by the device are now repeated in software with respect to 

other packets. 


Type: Defect 



Synopsis: Enumeration retry counter is not reset when a new device is attached. 

Description: Enumeration of a device is repeated up to three times if any error occures. The counter for the 

number of retries is not reset when a new device is attached. So if one device has already 

needed three retries, the enumeration of a new device will not be repeated at all if it fails the first 

time. 

Fix: Fixed

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: Suggestion, Component: DHCP (1 item(s)) 



Component: DHCP 

Category: Hostname and client identifier option 

Synopsis: Separate client identifier option 

Description: If chip.ini entry HOSTNAME_OPT is set, DHCP request are extended with the hostname option 

12 and client identifier option 61. For both entries the Chip.ini defined device name is used. The 

usage of hostname for both options shall be improved. It's common usage to use the ethernet 

mac address as Client identifier. It is necessary to provide an extra chip.ini entry for the DHCP 

client identifier option 12. 

Fix: Implemented: If Chip.ini entry CLIENT_IP is defined, DHCP inserts the stepcified String into its 

request as option 12. If the reseverd keyword MAC_ADDR is used, DHCP inserts the ethernet 

address. If CLIENT_IP is not defined, but HOSTNAME_OPT=1 is set, DHCP will still insert the 

chip.ini device name. 





Category: Findfirst/findnext 

Synopsis: Recursiv call of findfirst/findnext fails 

Description: Recursive calls into DOS findfirst()/findnext() operations fail due to use of static data within the 

implementation. 

Fix: Add FindNext.C module to AMXFS, to replace existing _findfirst()/_findnext() implementation. 

This new implementation saves the directory scan context in caller's ffblk data structure, which 

makes the function now reentrant (See new fjffPark() and fjffResume() functions).

Synopsis: Add a new semaphore API function to lock/unlock the bus 

Description: If multiple tasks use the SPI hardware master interface to access different slaves through 

different slave chip select PIO pins, this new call should be used to synchronise the SPI activity 

on the bus. 

The external MMC/SD driver example uses this call since version V1.02. 

Fix: Implemented new service 0xA8 

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



Component: TCPIP 

Category: IPETH command 

Synopsis: IPETH without ethernet initialization
