Circuit Playground Bluefruit forcing OTA DFU mode
khanning opened this issue · comments
After applying the latest precompiled bootloader + SD for the Circuit Playground Bluefruit (circuitplayground_nrf52840_bootloader-0.2.12_s140_6.1.1), the device forces itself into OTA DFU mode (purple neopixel ring).
Holding down either button while resetting allows the device to enter CDC/UF2 DFU mode. However, on subsequent resets the device forces itself back into OTA DFU mode so there doesn't seem to be a way to run application firmware after a reset.
Set up
- Circuit Playground Bluefruit
- Mac OSX 10.14.6
To Reproduce
Steps to reproduce the behavior:
- Place Circuit Playground Bluefruit in CDC/UF2 DFU bootloader mode
- Apply new bootloader + SD
adafruit-nrfutil --verbose dfu serial --package circuitplayground_nrf52840_bootloader-0.2.12_s140_6.1.1.zip -p /dev/tty.usbmodemXX -b 115200 --singlebank --touch 1200 - After receiving success message, the device enters OTA DFU mode (purple neopixel ring)
Starting DFU upgrade of type 3, SoftDevice size: 151016, bootloader size: 29200, application size: 0
