How to recover s32k controller if secure boot loader gone bad

[murugesan_dinak]

After I flashed secure boot loader, that micro controller went to reset mode. I used Trace32 to flash boot loader and application.

Trace32 was showing "target reset detected" always.

Hello,

When the strict sequential mode fails and the MCU is stuck in reset, I'm afraid there is no way to recover it.

Since the CSEc keys are allocated, the MCU cannot be mass erased and because the MCU is in reset, the keys cannot be erased either (with CMD_DBG_CHAL and CMD_DBG_AUTH commands).

Regards,

Daniel
