Compiler/TDA2: DSP2 crashed after __c_init00 , before main() was called
Part Number: TDA2
Tool/software: TI C/C++ Compiler
The cgtc6000 comiler v7.4.2 is used in the latest visionSDK3.05. The v7.4.2 comiler is not enough for our project, the v8.x.x is OK.
In below thread,
Rishabh Garg told me that the visionSDK3.05 will upgrade cgtc6000 comiler to v8.x.x two month ago.
But visionSDK 3.05 still use v7.4.2 when it was released.
So when will visionSDK upgrade cgtc6000 compiler to v8.x.x?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Bao Shang:
When I debug it:
(1) I set a break point at "_c_int00" for DSP2.
(2) I load the DSP2 exectable file "vision_sdk_c66xdsp_2_release.xe66".
The CCS show : Can't find a source file at "/db/ztree/library/trees/xdctargets/xdctargets-l07/src/ti/targets/rts6000/boot.c"
I locate the path as "PROCESSOR_SDK_VISION_03_05_00_00\ti_components\os_tools\bios_6_46_04_53\packages\ti\targets\rts6000"
(3) Then debug step by step to fuction "_auto_init_elf", I just see the program crashed at below code seciotns, and crashed at function "memcpy" :
if (!(&__TI_Handler_Table_Base >= &__TI_Handler_Table_Limit))
table_ptr = (unsigned char**) &__TI_CINIT_Base;
table_limit = (unsigned char**) &__TI_CINIT_Limit;
while (table_ptr < table_limit)
unsigned char* load_addr = *table_ptr++;
unsigned char* run_addr = *table_ptr++;
unsigned char handler_idx = *load_addr++;
handler_fptr handler = (handler_fptr)(&HANDLER_TABLE)[handler_idx];
(*handler)((const unsigned char*)load_addr, run_addr);
Exception at 0x857ad40c
857ad380 000000a0 rts6600_elf.lib : memcpy64.obj (.text:memcpy)857ad420 000000a0 : modf.obj (.text:modf)
(4) Once time , I see the program crashed after execute " table_limit = (unsigned char**) &__TI_CINIT_Limit;", maybe due to the symbol not match.
(5) I attach the AppImage and vision_sdk_c66xdsp_2_release.xe66. You could try on your board, the DDR size is 1G.
