Use DVRRDK and CCS to debug dsp code on DM8168

li zhanbin

HI:

we do our development on dm8168 DVR board,and dvrrdk_02.00.00.23 develop kit is used.I want to develop our dsp alg on dm8168.So I modify SCD alg to implement our alg. After A8 booting and load .xe674, I conecting dsp core and load symbols under CCSV5,.

But I can't find any symbols to debug dsp code, It is also when I remove the -o option and add --symdebug:dwarf option in the makerules path。

Is any one who can help me？

what should I modify to load dsp code symbols.

Thank you.

To be able to debug DSP code by single stepping pls do the following:

1. Enable -g

2. Remove --optimize_with_debug flag.

3. Remove -o3 optimization flag.

Note that BIOS and IPC are built with optimization even with above options as they are built with separate build options. Let us know if you require to be able to single step thru bios and ipc libs as well and I can post the options in RDK build.

Hi Badr:
after set single steppings you referred, can i run alg step bu step,
and set breakpoints?
or just run the .xe674, no c program match it in CCS5
