How to download micropython 1.21.0 ?

[patfrench]

Hello,

I'd like to build a version of micropython 1.21.0
I've downloaded the zip file from sourceforge but I'm having problems building it:

or maybe there is another solution ?

make -C mpy-cross
cd port/rp2
make submodules : error => parent directory is not a git repository

Thanks in advance

I succeeded:
git init
git add .
and then ok

On the other hand, now that I'm trying to migrate from evolutions 1.19 to 1.21 I always get the same error message:

CMake error at CmakeLists.txt:83 (add_executable):
cannot find source file:
/src/tusb.c

I admit I'm not a CMAKE expert

thanks in advance

The most reliable way to build a firmware is starting with cloning the whole MicroPython github repository. Then you can run make submodules. After that, you have the full set of files. And you have access to every version of MicroPyhton.
