Well once the fixes are in, I don't see any reason to not add multimaster support. > Also I have a draft version of mixed multimaster/slave version.

And TRM not as detailed as DSP TRMs. I think we can pretty easily test the i2c support before things get merged. I guess it should then be possible to loop two i2c controllers and run automated tests on them :) > Looks, like you haven't seen my response in another thread[1]. > So, duplicate it here. Sorry I guess I forgot to reply, let me know if I still missed something. I'll give your two fixes a try on Monday hopefully. Regards, Tony
