How to download and install mpremote with romfs command?

[wnelis]

As vfs.rom seems to be available in a short term (in a daily build of v1.25.0), I would like to download and install the associated mpremote tool, in order to create and fill the ROMFS. It will replace mpremote v1.24.1. How to download and install it?

[jkorte-dev]

you can find the latest mpremote in

tools/mpremote/mpremote

of the micropython repo.

So clone the repo; then run

pipx install ./tools/mpremote

Adjust the path as needed

Thanks. After a few tries the new version of mpremote was installed. However, option "-U" was not recognized by pipx.

Oops, that is indeed a pip option😬

Corrected

On linuxmint, you can simply do:

$ mpremote --version
mpremote 1.23.0
$ pip install /home/sharil/MP/20250226/micropython/tools/mpremote
...
Successfully built mpremote

$ mpremote --version
mpremote 1.25.0rc0.post316+g78728dc94

You need to change the path where you cloned micropython.

Thanks. Next time I'll try pip i.s.o. pipx, however with one additional parameter: pip install --user /path/to/mpremote.
