Seems that this #3597 might be the cause.

I don't have a T-Beam Supreme, but maybe @oseiler2 can have a look.

@Manasovo - Cannot say; do not currently have access to location where the tbeam-s3-core is running and it is still on 2.3.4.ea61808 Beta
. Sorry about that.

Version 2.3.13 seems to be stable, the serial port works and shows no errors after about 24 hours. I will test further.

I wonder if the T-Beam, with FW 2.3.6.7a3570a Beta
is stuck in DFU
(or whatever) mode? I did notice during one of the rollbacks to 2.3.4 that I did not have to do the funky dual button press to make it accept new FW from the web flasher - it was ready to accept new FW immediately after booting with no button presses. Maybe this will help...

Let me have a look
from firmware.
It seems that we do need ARDUINO_USB_CDC_ON_BOOT=1
after all in order for the CLI to work with the ESP32-S3. Otherwise I cannot get the S3 to read from USB Serial.
Issue #3650 that can cause the S3 to block on boot when no Serial is connected (and is triggered by ARDUINO_USB_CDC_ON_BOOT=1
in combination with ARDUINO_USB_MODE=1
) has recently been fixed in arduino-esp32 @ 2.0.15 . I've confirmed that using platform_packages = framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32.git#2.0.15

Thanks! Will give this another try on next beta branch FW release.

I just flashed a TBeam S3 with 2.3.9.f06c56a Alpha and I am still unable to get a serial connection over USB.
from firmware.
I have the same issue with firmware 2.4.0.46d7b82 and 2.3.15.deb7c27. I have not yet had the time to try 2.4.1 or older like 2.3.13 and lower.
In short the USB serial port is not working, it is not possible to read data from it and after some time it disappears even with /dev/tty.
Are you not noticing on tbeam-s3-core again the same behavior you described @GregEigsti ? THX
