I am using Code Warrior to erase the flash of a board of MPC8379e. Unfortunately, I failed with the message of "get flash ID failed". But, I succeeded in another board of the same type. For the board with problems, almost all the relevant chips and signals were checked thoroughly with the findings that there were no signals to the pins related to flash during the process of erasing. What are the possible reasons? Can anyone help me please? Thanks!
Below is my flash configuration.
Below is the logs of CodeWarrior.
