Hi all,
Using the adafruit Metro M4 Express AirLift, I started the tutorial on https://learn.adafruit.com/adafruit-met ... i/overview. After successfully updating the UF2 bootloader, verfying that arduino sketches work, I proceeded to update the ESP32 chip.
When dragging the file to the boot folder, it resets the board, and gets stuck. Only the "ON" led is on:
Any ideas?
Greatly appreciated any help!
Regards,

I should clarify: It fails when installing the Metro_M4_WiFi_ESP32_Passthru.UF2 file.

Re: Updating ESP32 on Metro M4 Express AirLift fails
O, nevermind. It apparently worked flashing the passthru bootloader. However, when querying the /dev/tty* / /dev/cu* devices, no different names where there, but the device was available under /dev/ttyACM0.
Thanks!
