I ordered two meshtastic kits, with no screen or GPS. I have one up and running fine, flashed with the latest bootloader and meshtastic firmware f7c6955 (using meshtastic-flasher). I am able to connect over serial to the working one and I see the meshtastic router output working normally.
On my second unit I am able to mount it as USB and update the bootloader and use meshtastic-flasher to flash it, but upon powering it up or resetting it, the red LED comes on and stays steady and the green LED pulses for maybe 100 milliseconds and then becomes steady, and at this point both red and green LEDs stay on steady indefinitely. When I connect over serial I see no output. Any ideas?
