esp32

MicroPython version

I have a problem on 4M variant of ESP32S3 (ESP32S3 Super Mini)

4M variant of firmware working good, without any problems.

But 4M firmware download is missing now on Micropython firmware download page.

I try to flash "universal" firmware v1.25.0 (2025-04-15)

and now my Filesystem not working.

MPY: soft reboot
Traceback (most recent call last):
File "_boot.py", line 11, in
File "inisetup.py", line 38, in setup
File "inisetup.py", line 7, in check_bootsec
OSError: (-24579, 'ESP_ERR_FLASH_NOT_INITIALISED')
MicroPython v1.25.0 on 2025-04-15; Generic ESP32S3 module with ESP32S3

I try to compare 4M firmware and new firmware, and partition table at adress 0x8000 in flash memory is different.
Partition table in new firmware is for 6MB filesystem.

Please bring back the 4M variant of Micropython

Reproduction

Download new image from Micropython website for ESP32S3
https://micropython.org/resources/firmware/ESP32_GENERIC_S3-20250415-v1.25.0.bin

Upload it to 4M variant of ESP32S3 and open REPL

Expected behaviour

I expected working filesystem, but vfs partition is broken now.

Observed behaviour

Flashing back to 4M Variant firmware helps... but for other people 4M build is missing now on download page
