M1G Status Led - Two fast blinks

Hi

I have an M1G which has the status LED doing two fast blinks. According to the manual this is "Control running on bootloader only".
I can't connect with RP.
The first and only KP shows KP 1 Lost Comms.

TIA

The M1 is in the bootloader mode awaiting a new application code to be sent to the M1.

Did you start downloading a new application code and stopped?
