Hello, I need help finding the ECC writing algorithm. I need to change one byte and fix ECC in binary. How to calculate ecc

Hi ,

Kindly refer the KBA "ECC Injection Tests in Traveo MCUs - KBA225469" for details on ECC injection for testing  . Also, kindly refer section 3.8 of Chapter TCFlash in your device Platform H/W Manual for details on ECC Generation and Check.

Hi,

As discussed , we cannot just modify the binary and flash (it may lead to checksum failure), you need to check with the application code developer (check with your vendor who created this binary, since Infineon has not created the application) to do the necessary changes in code, and recompile and  then flash the binary. And for the query on ECC calculation, we have already provided the response in 1st reply.
