When i debug my project, i find sometimes the code doesn't go to main. Normally i can relaunch the debug session successfully.

I tried to pause the session to check where was the program stuck.

I step into further, and i found my code was running but no output. I don't known what cause these thing happen? it should be stopping at main.

One more, When the program doesn't go to main, i always fail to ping DSP.

PS: My environment is
PDK: pdk_omapl138_1_0_1
NDK: ndk_2_20_06_35
board: LCDK6748
CCS: 7.2

I've forwarded your query to the software experts. Their feedback should be posted here.

Jiawei,

It appears that when you pause the code the core is executing in the DDR memory. Can you reset the CPU and then reload the code. It appears that interrupt, global variables or stack is not going to initialized state. core interrupts, internal memory should be re-freshed after CPU reset and system reset should set all peripheral registers to reset state so try with CPU reset first. Also ensure that core is booting in UART/emulation mode and not from flash boot mode, which can cause the image in the flash to load after reset.

Regards,
Rahul

My boot mode is NAND now. You mean that i should change it to UART mode and reset CPU and sytem register before debugging my program. I'll give it a try. Thank u for your reply, Rahul Prabhu.
