I'm having trouble flashing a binary to the ESP32 on the AI deck.

I'm able to flash to the GAP8 through cfload, following the example here, so I know that cfload, the crazyradio, and the ai deck are all on and configured correctly.

I've built the aideck-esp-firmware via the docker command. When I try to run cfloader flash build/aideck_esp.bin deck-bcAI:esp-fw -w radio://0/80/2M/E7E7E7E728 I get the following -

         `

And the flash never completes. Note, the errors that I'm seeing were there during the successful gap8 push. Also, the LED2 is flashing slowly and the LED1 is flashing quickly.

Any advice would be appreciated!
