Hi,

It's pretty straightforward. You need the devel/gcc-arm-embedded package, and
need to set the PICO_TOOLCHAIN_PATH environment variable to
/usr/local/gcc-arm-embedded.

After this, you just need to follow what's in the pico_setup.sh file; basically
clone pico-{sdk,examples,extras,playground} and set the corresponding
environment variables (PICO_$REPO_PATH) to where you cloned them.

You can also clone the picotool repo, which builds without a problem, and
Raspberry's OpenOCD, which needs some tweaking after the bootstrap step:

$ sed -i.bak -e '/PKG_CONFIG/{/1\.0/!s/libusb/&-0.1/;}' configure
$ ./configure --disable-werror CFLAGS='-I/usr/local/include' LDFLAGS='-L/usr/local/lib'
$ gmake

You'll also need the devel/gmake package for this.

Hope this helps.

Cheers,
Toma
