Flash erase for LPC55S69-EVK fails

[romlinux]

Hello,

I recently got a LPC55S69-EVK. I was trying out some sample programs and it worked fine. Recently, though the flashing procedure is failing. I have power-cycled the board several times but the situation did not improve. Am I missing something. Thank you.

Please see the logs below:

Hi Romit Dasgupta

What's your LPC55s69 EVK board version?

Some early pre-release version of LPC55s69 EVK has on board Flash defect.  but if you purchased the board from NXP web site, the mass erase should work without problem. Besides Romit's suggestion, please check attached video of how to do mass erase with the tool.

Have a great day,
TIC

I found the solution to this via mass erase.  Please see the thread on how to mass-erase the flash.
