@ajb2k3 Ok. First I will try formatting with Thonny and if it doesn't work I will try this last tip. Thank you so much for the info.

@winni Hi! I didn't know about Thonny software. I'll see if I can find it and try if it works for me. Thank you very much.

@ajb2k3 I'm using a Mac Book Pro (2018) with Mojave.

Installing Marauder Firmware worked for me on the first try. This was the same day I received the M5Stickc Plus and without knowing anything about the device, I decided to try the first things I found on the internet. Now that I have learned a little more, I want to connect it with UIFlow but the M5 Burner application gives me an error and I cannot use the device. Does anyone know how I can reverse or solve this problem?

M5 Burner's error message:

--chip auto --port /dev/tty.usbserial-7952F10C48 --baud 1500000 --before default_reset write_flash -z --flash_mode dio --flash_freq 80m --flash_size detect 0x3ff000 /Applications/M5Burner.app/Contents/Resources/packages/tmp/wifi.bin 0x000 /Applications/M5Burner.app/Contents/Resources/packages/firmware/73ac327924a36f04c038a54fc2147b30.bin

Thank you so much!

Tengo un problema de novato. Nada mas comprar el M5 Stick c Plus lo flashee parara instalar un firmware independiente que vi por ahi. ahora quiero empezar a usarlo con normalidad con la App M5 Burner, pero no me reconoce el dispositivo, cuando le doy a Burn, me da error y no puedo volver a tenerlo como venia de fabrica. He buscado mucho y no encuentro ninguna información de como hacerlo, si alguien sabe iluminarme, seria genial. El mensaje de error que muestra siempre es el siguiente:

--chip auto --port /dev/tty.usbserial-7952F10C48 --baud 115200 --before default_reset write_flash -z --flash_mode dio --flash_freq 80m --flash_size detect 0x3ff000 /Applications/M5Burner.app/Contents/Resources/packages/tmp/wifi.bin 0x000 /Applications/M5Burner.app/Contents/Resources/packages/firmware/73ac327924a36f04c038a54fc2147b30.bin
