I would like to use a regular x86 processor with Linux (stripped down)...
to avoid recompiling Python itself...to avoid one more variable in the
entire process. What was the processor/OS combination you mentioned earlier

Compiling the Python code to ST means, writing a compiler :))...which will
be a serious project in itself. and then I will loose all the good things
that come with Python.

This field badly needs Python :))

Thanks and best regards,
