Hello Support,

Flash EEPROM ECC starts at 0xF010_0000

But nowECC is generating ECC data at address 0x1544_0000.

Attached file contains a test case file in zipped format with the command shown below:

"C:\Program Files\Texas Instruments\nowECC\v2.17\nowECC.exe" -i .\fee.hex -f021 16M_ADD -r4 -a -o .\fee_parity.hex

Thank you.
Regards
Pashan

Hi Pashan

I verified and observed that your finding is correct. This is a bug in nowECC. With Intel hex files as input and data in the EEPROM address range, the start address of the ECC section is not computed correctly. This will be fixed in the next release.

This issue occurs only with Intel hex files. It works fine with other input file formats .

Siddharth
