ESP32S3 4M Port missing. Partition table in Firmware in file is wrong
Port, board and/or hardware
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 <module>
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
Additional Information
No, I've provided everything above.
Code of Conduct
Yes, I agree
ports/esp32: add FLASHSIZE_4MB variant to ESP32_GENERIC_S3
Added a 4MiB flash partitioning variant for ESP32S3:
don't know how many 4MiB discrete flash board are out there, but there are some with the ESP32-S3FH4R2 chip with embedded 4MiB flash, like waveshare ESP32-S3 Mini (also known as ESP32-S3-Zero), which do not work with 8MiB partitions -- the filesystem partition is missing entirely
tested on the mentioned above waveshare ESP32-S3 Mini w/ESP32-S3FH4R2
