MCSDK-Video dsp code debug

Hi Ruisucom,
I guess you are using MCSDK video framework? If so, please see below high level steps

1) Please disable disable optimizations.
optimization flags can be temporarily turned off by commenting out the following line in dsp\mkrel\c64x\makedefs.mk:
C_OPT_FLAGS = -mt -mw -os -o3 --optimize_with_debug --> #C_OPT_FLAGS = -mt -mw -os -o3 --optimize_with_debug

Then rebuild SV04 (make clean, make sv04)

2) connect JTAG and plug board in PCIe slot.
3) Open CCS, and create target (you can add 4 TMS320C6678 devices in order to create a quad shannon)

4) connect target, connect cores

---> If it is not a fresh start please press F8 to run the cores-->

5) In Ubuntu go to MCSDK video PCIe demo folder script and run: ./reset_dsp.sh followed by ./dnld_dsp.sh
6) In CCS: halt cores and load symbols (SV04)
7) Add Breakpoints in CCS (if required)

8) In CCS, press  F8 (run free all the cores)
9) Finally in Ubuntu run ./demoSave2file.sh

Please note that delivered HEVC libraries are in release mode and you cannot step inside the lib.

thank you,

Paula
