Build how to?!?

[jedie]

I would like to start, building my own firmware image with my own frozen modules.

I found the "basic" build instructions here: https://github.com/micropython/micropyt ... structions

But this doesn't contain information about frozen modules.

Is there somewhere a project that will compile a own firmware? So i can look, how this can happen?

[kevinkk525]

Check my scripts in "tools" directory. It copies to the frozen module directory and builds the firmware. Even have a script to set up the building environment.

I've figured some stuff out by myself. Current work is here: https://github.com/jedie/micropython-so ... ch/pull/32

The destination is to have just a "update.sh" and a "compile.sh" ...

Current problem is xtensa-lx106-elf-standalone.tar.gz from https://github.com/jepler/esp-open-sdk/releases contains a very old xtensa-lx106-elf/bin/esptool.py
This is v1.2 and works only with Python 2... so it's crashed:

Is there somewhere a new version of xtensa-lx106-elf-standalone.tar.gz ?

I will take a look at this, thanks!

btw. have you tried to build the firmware as github actions? I try this. Current output: https://github.com/jedie/micropython-so ... /367018243

[kevinkk525]

I have never tried that, looks interesting.

Found a solution here: https://github.com/kevinkk525/pysmartno ... .sh#L8-L10
I will try this, too.

The idea is that a action creates a new github release.

I’ve had good success with the Docker image recommended by jimmo. Really easy, nothing to install except Docker, no versioning conflicts.

Good idea: But the https://hub.docker.com/r/larsks/esp-open-sdk image is also 2 years old. I try a new build.

WIP: https://github.com/jedie/docker-esp-open-sdk
Image is available here: https://hub.docker.com/r/jedie/esp-open-sdk/

EDIT: https://github.com/jedie/docker-esp-open-sdk works now: build and pushed to docker hub via github action...

Now i started https://github.com/jedie/docker-micropython/ to build and push a docker image for compile esp8266 images...
It's hanging with:

Any idea?


EDIT: Found the problem: It's needed to build esp-open-sdk via "make STANDALONE=y" ... I fixed with: https://github.com/jedie/docker-esp-ope ... 684ee8f56b

Now, compiling the esp8266 firmware works, see: https://github.com/jedie/docker-micropy ... =378453918
