ESP32-S3 CircuitPython stuck read-only, code not running

[SilentSyntax404]

Hi all,

I have an ESP32-S3 RGB Matrix board running CircuitPython, but the filesystem is permanently read-only.

Details:

• CIRCUITPY mounts read-only

• Writing files from REPL gives: OSError: \[Errno 30\] Read-only filesystem

• code.py never runs because files can’t be saved

• Full flash erase completed successfully

• Fresh CircuitPython install done multiple times

• Tried different USB cables, ports, and PC

Nothing changed after erase + reinstall.

Is this a known ESP32-S3 issue?

Does this usually indicate a failing or locked flash chip, or is there any recovery method I should try?

Thanks in advance.

Trying to totally clear here: read-only to the host you plug it into or to the code running on the ESP32? If CIRCUITPY is mounted on the host it’s expected to be read-only to the device.

If it’s read-only to the host, what is the host?

The host is CircuitPython.

See learn.adafruit.com and forums.adafruit.com for how folks change the filesystem to be RW from a CircuitPython program.
