Hi,
interesting. My conclusion would be you are jumping directly into the reset
vector without having and data/instruction abort? This would mean we directly
jump to 0x0 or wherever the reset vector is located at?
Debug proposals/ideas... maybe you have tried all these:
- Is Hello World surviving?
- If hello world is working, maybe your GSM neighborhood makes our
app just crash? Can you remove the antenna or go to a basement?
- The calypso has a special debug FIFO remembering the latest
instruction and data fetches, prom wrote some support for it... I'm
not sure it will survive the soft reset you are seeing... IIRC we
are relocating the vector tables, so we should be able to dump it
after a reset (in case the content survives that)?
sorry for the wild guesses, I have no idea if that is of any use.
