TMS570LC4357: flash eeprom ecc

Part Number: TMS570LC4357

Hi, What are the steps for checking eeeprom ECC and flash ECC in TMS570LC4357?

Which are the chapter where I can refer for the steps 

  • Hello,

    Flash Wrapper Diag Mode 7 and Diag Mode 5 can be used to test ECC logic. The same ECC logic in CPU is used for main flash and EEPROM.

  • hello, Thank you for the reply.

     I tried to follow the steps. Please address my below points

    1. Is the Diag Mode 5:  Address Tag Register test mode also used for the ECC test? How this is related?
    2. In step, one mentioned Branch to a non-Flash region. does it refer to the ECC region for flash from 0xF0000000 to 0xF047FFFF ?
    3. If I'm selecting port A, how do a port A read to the desired address. ?
  • 1. No, the diagmode 5 is to test address tag. It is not used for ECC test

    2. The test function should be copied to SRAM and executed from SRAM

    3. Port A and Port B are ports for bus masters to access the flash banks.
