TMS320F28388D: M0 init cause interrupt happen

M0 init will clear all the content of M0. Have you checked what are you using this RAM for in your linker cmd file ?

Hi Vivek,

Yes, It seems like there are global symbol used in these locations 

0 00000000 code_start
0 000001b1 FLASH_init
0 000002c8 SysCtl_delay
0 000002d4 __TI_Handler_Table_Base
0 000002da __TI_Handler_Table_Limit
0 000002de __TI_CINIT_Base
0 000002e6 __TI_CINIT_Limit
0 000002e6 __TI_CINIT_Warm

thanks,

Ken 

Then you should not do the RAMINIT for M0. That will cause issue.

Why do you want to do RAMINIT for M0 ?

yes, 

I will not do RAMINIT these locations for init.

Thanks,
