CCS/TMS320F28020: FOR TMS320F28020, how to locate the corresponding data storage location of 0X3F7FF7 in the.out file and manually change the data to the CRC check value calculated above?

Part Number: TMS320F28020

Tool/software: Code Composer Studio

I need to perform CRC check calculation on the data in the area of program store 0X3F0000_0X3F7FF6.

The CRC validation values (calculated using external tools) need to be written in advance in the memory area of 0X3F7FF7.

Confusion: how to locate the corresponding data storage location of 0X3F7FF7 in the.out file and manually change the data to the CRC check value calculated above?

Hello

If your CRC is checking 0x3F7FF7, couldn't you calculate the CRC on the OUT file and then assign the golden CRC to 0x3F7FF7 via the linker file, then re-compile. The newly generated OUT should come out to be the same CRC and also now contain the golden value.

Best regards
Chris
