[S32K144] Erase All Block

[KK2]

Hello,

FLASH_DRV_EraseAllBlock is not working.
I think this is due to enter secure state, and I have already tried the following

• "Emergency Kinetis Device Recovery by Full Chip Erase" in S32DS debug configuration window
• I set "#define ERASE_ALL_KEYS" to 1 in the sample project csec_keyconfig_s32k144 to reset the device back to factory state and ran it. However, the status of eraseKeys() became false.
• I try to use the P&E recovery utility mentioned in "https://mcuoneclipse.com/2013/06/16/bricking-and-recovering-frdm-kl25z-boards-reset-swd-clock-and-lo... but it did not result in Success.

wish you help

Best regards.

Hello,

It could be because some of the keys are write-protected.
