what is wrong ?

Try it like this: https://github.com/kevinkk525/pysmartno ... ository.sh

Thanks for script.

Finally, after long compilation i have got a hand made firmware-combined.bin (641276K)
But it doesnt work.
No python prompt. Only garbage in terminal.

While looking for esp-open-sdk compilation issue i installed many packages which caused invalid custom firmware.
I reinstalled Ubuntu and now everything is ok.

Note: To avoid many errors don't use python virtualenv.

Thanks kevinkk525 once more !

Glad you got it working! There is also a docker option but I never played with that one as I'm building in ubuntu wsl.

docker mentioned in official documentation.
sudo docker run --rm -v $HOME:$HOME -u $UID -w $PWD larsks/esp-open-sdk
docker: Error response from daemon: No command specified.
so i went your path using git

I also visited your project pysmartnode and found there a script for esp32 firmware compilation.
https://github.com/kevinkk525/pysmartno ... ository.sh

thanks for tip

there is, but I'm not sure the esp32 script still works.. there are always changes and something always breaks.. I gave up on building esp32 firmware and only use official ones and copy the prebuilt .mpy files onto it. It has enough RAM to do it this way and it makes it easier to update my files.
