Hi Yuri,

I'm using UDOO quad and I stuck in this 1588 issue two weeks.

My timestamp wasn't counting, I want to put timestamp in my ethernet packet but the program caught the same timestamp again and again. I read all of the documents about this issue but still confused.


1. How to select the GPIO 16 to ALT2 mode? How to set the SION bit? Using command or I need to modify the kernel source code?

2. If I use the image which is provided by UDOO, can I still enable the 1588 feature? 


Best Regards,
