Other Parts Discussed in Thread: MSP430FR2422, , MSP-FET
I got some boards from our production line that did not pass our board tester, they failed on the MSP bootloader program step.
We are using MSPFlasher 1.3.16 with the following command:
MSP430Flasher.exe -n MSP430FR2422 -w bootloader_V2.0.hex -v -z [VCC=3300, RESET] -i USB -e ERASE_ALL
For some reason we sometimes get the error "The Debug Interface to the device has been secured" but these devices are brand new from the reel!
Show how is this possible? Is there a way to unlock the MCUs?
