Team,
A customer is trying to use "call stack" for post mortem analysis to analyze a system that crashed. Description on what he does is below in blue.
Q: Does the "call stack window" only relying on the system stack or are there information recorded by CCS during execution to keep track of the fct calls (like recording B3 register at every fct call)?
In fact we are trying to understand if it can realy be used for post mortem analysis.
Information from customer:
I'm currently working with DSP 6488 & CCS 3.3.82.13. After collecting
post-mortem dumps from the board, I'm loading them under CCS. I've a GEL file
which allows to restore core registers from the post-mortem data. Then I use the
call task feature under CCS and the result is not the expected one. Instead of
getting the names of the calling functions, I see some addresses in hexadecimal
or names of data varaible.
We do the following:
- memory
dump from the board
- load data under CCS
- restore core registers
-
use call task feature
Thanks and best regards,
Anthony
