TMS320F28377D: Is these code right for reading RESC at RAM 0x002C

Part Number: TMS320F28377D

Hi Team,

My customer use the code below to read RESC at RAM 0x002C:

1
2
3
4
5
6
7
8
9
#define BOOTSTATUS 0x0000002C
Uint16 *pusCPU01BufferPt;                   //发送内容指针
Uint32 *BOOTSTAT;
BOOTSTAT = (Uint32 *)BOOTSTATUS;
pusCPU01BufferPt[15] = ((*BOOTSTAT)>>16);   //高位
pusCPU01BufferPt[16] = *BOOTSTAT;
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

#define BOOTSTATUS 0x0000002C

Uint16 *pusCPU01BufferPt;                   //发送内容指针

Uint32 *BOOTSTAT;

BOOTSTAT = (Uint32 *)BOOTSTATUS;
pusCPU01BufferPt[15] = ((*BOOTSTAT)>>16);   //高位
pusCPU01BufferPt[16] = *BOOTSTAT;

Does these code work properly for reading reset source which stored by BOOT ROM?

Thanks & Regards,

Yale,

The question is not clear. Does it pertain to reading the Reset Cause register at offset 80h? Once you confirm, a S/W expert will help you.

Yes, but this register can not read directly because it will be clear by Boot ROM after reset.

Thanks & Regards,

till line 7 it is fine and i dont understand the reason for storing in array indexed to 15 and 16.

you can store in a variable to check if you are able to get the status information correctly.

Then you can store in pointer/array.
