Hi all!
This is the "latest" version of our porting to Taskit PORTUX 920T mini-pc.
Thank to Achim Ehrlich - we got all we needed working! Timing has been set
to s$
Basically - we have seen:
- dataflash working
- usb transfers ok
- environment
We should test other hardware - hoping to get feedback, at least from
Taskit!
Thank to all the people helped us!
