CircuitPython version and board name

adafruit-circuitpython-lilygo_tdongle_s3-en_GB-9.2.5.bin

Code/REPL

The REPL never reaches a point to execute code and the CIRCUITPY drive never appears.

Behavior

After flashing the circuitpython binary, no USB drive appears and the REPL prints the following repeatedly.

Description

No response

Additional information

I have managed to get MicroPython running on the dongle using the firmware that LILYGO provides in their repository.

In https://github.com/adafruit/circuitpython/pull/10065/files#diff-75938e484e23c93e62559507d7c14b81ecfebf40557f4cd03aa4dcad99ea56e3R12 it looks like the dongle expects to have PSRAM but LILYGO's schematics don't look to include any PSRAM.
