we have a couple of devices with a p1 and made a mistake not connecting reset and mode correctly. as long as all is well the are not needed… we have some precautions in the code we flash (long delay) so we could reflash the device is something wrong with the code
but you guessed it… something went wrong and we cannot reflash them. we did bring out the swclk and swdio pins (d6, d7). is it somehow possible to reflash using these and a programmer? or are they bricked forever?
