I have custom desgined boards using the PJRC bootloader and NXP chip, they work very nicely!
It was time to test the locking feature so I fired up Arduino and ran through the 4 steps. First creating a new certificate, I then ran the 3 steps to lock it. Every step was successful in the serial monitor.
Here is where the weird stuff happens. I try to flash it with a blink sketch and it wont do it. I click the boot button and the device restarts, but it takes almost a minute before I hear the windows sound. When it's connected again, it doesn't appear anywhere.
Basically it's bricked as it can't be flashed anymore. Looking at the serial terminal, the board is still running that 3rd (last) sketch.
I've tried this with a total of 3 boards, all the same!
Any ideas?
