TMS570LS0714: FLASH_ECC_TEST_MODE_2BIT Problem

Lorenzo Nava73

Part Number: TMS570LS0714

Hi,

we use a TMS570LS0714 and have implemented the diagnostic test for the Flash in our application firmware.

Periodically we run this tests with test type FLASH_ECC_TEST_MODE_2BIT but the firmware hang after the instruction:

flashread = *(volatile uint32 *)flashBadECC2; (line 1280 of sl_selftest.c version 2.4.0)

How can we manage it?

 

NOTE: In the first part of the flash (from 0 to 0x0020000) we have made a custom bootloader version with ECC disabled. It could be a problem?

Thank you.
