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

Reproduction
In according to official guidance , open powershell echo：
esptool --baud 460800 write_flash 0 .\ESP32_GENERIC_S3-SPIRAM_OCT-20250415-v1.25.0.bin
click RST button，and open thonny，execute
import esp
import gc
print(esp.flash_size())
print(esp.flash_user_start())
print(gc.mem_free())
you will find a problem like result below.
- First line is flash size ,equals 8M，corresponds to rom
- Second Line is user partition start，I know，
ESP32_GENERIC_S3-SPIRAM_OCT-20250415-v1.25.0.binis 1.5M , from 2M maybe reasonable. - Third Line is mem_free, corresponds to ram .

Actually my board is N16R8, means 16M psrom and 8M psram. after using Micropython bin, I got 8M rom , and 8M ram ,where is 8M left from flash?
I chose OCT version bin due to 8M psram, but normal and OCT version both miss flash size. I don't know why and how i need to do or it's something being limited.
And thonny is also 6m，maybe 8M-2M?

Expected behaviour
get missed 8m flash size for using
