ESP_ERR_FLASH_NOT_INITIALISED - ESP32-S3 version

Open Digital-Apprentice opened this issue 2 months ago • 1 comments

Hi, After uploading the version for S3, the following error appears:

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 v1.24.0-dirty on 2025-10-27; Generic ESP32S3 module with ESP32S3

My board: ESP32-S3 Matrix (LED 8x8 RGB) - 2MB PSRAM, 4 MB Flash

Maybe we could also upgrade Micropython to 1.26.1 and espidfs to 5.4.2? There are no errors when installing pure Micropython version 1.26.1. Since 1.25 the esp32 port now supports IDF v5.3 and v5.4, and support for versions below v5.2.0 has been dropped. There are a lot of improvements in the new version that would be very helpful.

Regards Thomas

I'm not against moving to 1.26. Do you want to create a PR?
