RE: [ECOS] flash erase - network stack

["Nicolas Brouard" <nicolas dot brouard at silicomp dot ca>]

The code I execute is in RAM.
I can debug my code using RedBoot in FLASH with network debugging.
I put breakpoints in the function ip_input (ip_input.c) and in the function
icmp_input (ip_icmp.c)
I ping my application (not RedBoot). GDB breaks on input and on icmp_input.
I continue step by step then I go to icmp_reflect function, etc...
If I do that during erasing flash, I have a SIGILL signal (Illegal
instruction).

It looks like you are trying to use (execute from) the FLASH while
executing the erase.  You don't happen to be using RedBoot in FLASH
with network debugging while running your code, do you?
