Hi Aliff

we can close this support request! +1.1V for the HPS system was not working as expected. For this reason the J-TAG chain was not working properly in the HPS part. From the beginning I was pretty much sure that this might be the reason but I couldn't find the source..

Thank you very much for your time and help..
