If it stays purple than it is either a power supply issue, or something went wrong during reflash\upgrade. Please consider reflashing again if the power supply is fine.
reflashed with last version of firmware not working
with an old version. It worked well. Reach works but cannot connect with my Pixhawk. I cannot select UART in solution output path and erb is also missing. The version was 0.0.3…
The image has the old app version installed, so you will need to update after reflashing. The old 0.0.3 version lacks a lot of features, including ERB output.
