LED Indicators
USA Built
You will see both red and blue LEDs on the ARK Flow when it is being flashed, and a solid blue LED if it is running properly.
If you see a solid red LED there is an error and you should check the following:
Make sure the flight controller has an SD card installed.
Make sure the Ark Flow has ark_can-flow_canbootloader
installed prior to flashing ark_can-flow_default
.
Remove binaries from the root and ufw directories of the SD card and try to build and flash again.
