Use IAR for TMS570LS3137 calculate Flash CRC error occur

Other Parts Discussed in Thread: NOWECC, HALCOGEN, TMS570LS3137

I use IAR as IDE ,when I use the function

uint64 SL_CRC_Calculate (uint64 * startAddr, uint32 count64),which is provided by safety library ,I found some problems ,if the length I calculate is less than 0x30000 (this number is not very accurate ),no problem ,if the size of flash calculated is larger than this number , it jumps to flahErrorReal.

I want to know why this happened ,when I use CCS ,this problem dosn't exist.

Which MCU is this code project for? Can you upload the IAR project? Does your code program the ECC for the entire flash memory? CCS has an option to automatically generate and program the ECC locations for the entire flash. IAR EWB does not have this capability. You need to post-process the .out file using nowECC in order to add the ECC for the entire available flash memory before you program the code into the part.

The code projecet is for TMS570LS3137,I enable the ECC in the Halcogen .I will try your suggestion using nowECC

I use IAR to view the FlashECC memory,it has ECC data.I think the problem is about the set of the iar IDE
