Isaac, please feel free to include me on any discussions on the topic.
If you talk to your FAE and get a suitable contact name at ST and you do
not wish to take this on please send me the details and I will look into it.
My experience is these things take time and it is about informing and
highlighting the issues their licenses create.

Yes this is a strange situation. Xilinx is a good example of how they
support the development of open GPL code for Linux for their chips and
then they use a restrictive license on the SDK/BSP code that is
functionally equivalent and better suited to us. Same company, same
funding source, same devices but very difficult outcomes.

This can be true and tends to reflect internal corporate structures in
companies than technical reasons. Bringing about change here takes time
and patience. I am always positive chip companies want to make and sell
devices and we just need to keep reminding them their actions negatively
effect us directly and them indirectly.
