No idea, hopefully someone from Toradex could help us. I haven’t worked with this problem because there is many other on my desk, and I’m hoping to see solution for this. In my case update of edt driver was not solution therefore I assume this patching work is just wasting of time.
Meanwhile, while waiting Toradex support, you should clarify why all those ‘err -22’ are there after patching. Maybe you can first try to compile with simple patch file which actually does nothing but add some debug message into edt driver.
