Erase flash and try again.

Please share information about to board you use:

esptool.py --port $COMPORT flash_id

output should look similar to this one

esptool.py v2.8

Yes, every test on every version has been done erasing the flash and then flashing the code.

Here is the output.

I've tried flashing the release 2.05 using the --flash_freq keep option, but nothing changed.

The cpu frequency is part of the esp-idf configuration and is set to 240 MHz.

40MHz/80MHz is the SPI flash frequency setting.
It is not related to CPU frequency setting.
CPU frequency is set at the time this library is compiled,
and can not be changed afterwards.

If you want espruino on your board you have to go through the esp-idf setup process and create libs for 160 MHz. With those libs you can build a ESP32 160 MHz Espruino version.

different

Is there a way to change 160 to 240 MHz device wise?

Version 2.0 works perfectly.

I guess after that there where a switch from 160 to 240 MHz.

Ok. So I've to consider that this device will be not supported from higher release?

In the board there is no way to set the frequency.

Or build by your own, as mentioned above. To be honest not easy but not impossible.;-)

Ok. well, it seems very much easier to buy a newer board :)

Thanks for your support. To me this issues can be closed.

Ok, yes it is very difficult to pick a proper ESP32 board, there are to many.

Maybe you like to post a forum conversation and ask other users to name a recommendation for a board they use or tried with or without success.

Oh, wouldn't it be nice to gather the working or not-working boards "somewhere"? With date, board revision/version. Ok, might be asking too much...

Sure, just go and updare that source on githup

maybe in section Limitation
