I was using an Adafruit Feather nRF52 to develop our custom firmware for the PINETIME (as it has the exact same chip, but also serial, LEDs and so on). I also had the same behaviour with this board and the bcm2835spi driver. It worked for a day and a half (continuously connected) and after I power resetted it it stopped working. I'm getting the same error as @cjmakes . The firmware I flashed on the chip as when it worked the last time is still working so I don't think the chip itself is broken. But I think it could have to do something with the nRF52832. If anyone here has a solution I'd really like to know it.
