1. RAM Error:
On startup of the @CHIP-RTOS a RAM test will be performed. If it fails, the @CHIP prints the error message "RAM ERROR" on the COM port
(using 19200 Baud and 8N1, regardless the entry in the CHIP.INI). The @CHIP-RTOS freezes after the error message output (does not boot!).
2. Checksum Error:
During the boot process a checksum over the complete @CHIP-RTOS image in the flash will be generated. This checksum must be equal to the
checksum which was written with the @CHIP-RTOS update (in a special sector on the flash). If the checksum is not equal, the error message
"Fatal BIOS checksum error" will be shown on the serial console. The system will boot, but the execution of the AUTOEXEC.BAT will be
prevented.
3. Flash Error:
Every flash write access of the @CHIP-RTOS will be verified. If the flash access fails, an internal flag will be set, to mark the sector which should
be written as defect. On the next reboot the error message "Flash error at sector: xx" will be shown on the serial console. The system will boot,
but the execution of the AUTOEXEC.BAT will be prevented.
4. Network Error:
During the init process of the TCP/IP it could be possible that a network error occurs (mostly it is a hardware defect). In this case the message
"Fatal Network Error" will be printed on the serial console of the IPC@CHIP. The system will boot, but the execution of the AUTOEXEC.BAT will
be prevented.
