ESP32S3: Firmware startup but no lua prompt

[ThomasKaemmerer]

Expected behavior

Active lua prompt.

Actual behavior

I use the current state of the firmware sources to create the necessary images for this device. After successfully flashing and rebooting the device, the FW is loaded but not completely executed. No lua prompt appears and no further interaction with the device is possible.

Test code

How I would love to try out a lua snippet ;-)

I suppose, it expects you to upload some init.lua to the board for it to execute automatically.
