Hi all,
when DSPBIOS hang, it will trigger UTL_halt which call from SYS_abort.
So if without CCS, can we have method to get the call stack backtrace from the UTL_halt?
I mean we can hook the UTL_halt function, add some function like backtrace(...), then we can know where the execption happens.
Does is possilbe?
Currently we find out the code where the exception is triggered by setting breakpoint at _EXC_dispatch which is default entry point for all exceptions.
Then check the value of B3 register, which stores the function return address. Any method can do this without CCS?
Our hardware is Omap L138, BIOSDSP version is :5_41_02_14
thanks
