I have this issue where I can't debug or program any code in a FRDM-MCXN947, many troubles I've seen but this one is the latest

Hello, my name is Pavel, and I will be supporting your case, I recommend do a mass erase, or in other way maybe could change the firmware of the debugger.

Can you give me the steps to perform a mass erase?

Hello, I recommend use the SPDK and on the environment use the BLHOST to do a mas erase.

Installation Guide — SPSDK documentation

MCUBLHOSTUG.pdf

On the link above BLHOST could use the command get property 1 to confirm the board has communication (on ISP mode) with the Host, then use flash-erase-all.

Best regards,
Pavel
