corrupt filesystem after flashing

[christianwicke]

Hello toremick,

I can flash the firmware without error, but when I try to connect with thonny the filesystem seem to be corrupt:

The filesystem appears to be corrupted. If you had important data there, you
may want to make a flash snapshot to try to recover it. Otherwise, perform
factory reprogramming of MicroPython firmware (completely erase flash, followed
by firmware programming).


Device is busy or does not respond. Your options:

  - wait until it completes current work;
  - use Ctrl+C to interrupt current work;
  - reset the device and try again;
  - check connection properties;
  - make sure the device has suitable MicroPython / CircuitPython / firmware;
  - make sure the device is not in bootloader mode.

(keeps on repeating)

I can press Ctrl-C and enter the REPL. But installation fails because of the corrupt filesystem:

However, I can flash MicroPython using thonny if I follow these instructions: https://randomnerdtutorials.com/getting-started-thonny-micropython-python-ide-esp32-esp8266/ . Then the filesystem is not corrupt.
I use this esp32: https://de.aliexpress.com/item/1005001838731651.html

Do you have any clue, what is going wrong?

Could you provide the installation module? Then I would try to install it over a bare MicroPython firmware.

Thanks a lot for your help and for sharing your project on github!

I found a workaround:

• After flashing MicroPython v1.23.0 I copied the main folder and the config.py to / on the esp32
• I also copied the main_example.py to boot.py on the esp32
• Small modifications to the code were necessary to get it running with MicroPython v1.23.0 (module ussl is now ssl).
• I documented this at https://github.com/christianwicke/shorai-esp32. The modified code is also there.

Afterwards I managed to control my Seiya air conditioner over mqtt.
