Minimal Cyclone V SE Testsystem on DE0-NANO-SOC: Uboot dies right after FPGA config

Hi, I made a minimum System in Quartus 15.1. The Qsys Systems consist only of an AvalonMM UART and a 8 bit PIO for the LEDs. The only bridge used is the lightweight HPS4FPGA one (in32bit mode)....

Unfortunately there is little feedback in the rocketboards forum. I think this forum here is way more active. I followed this instruction from the mailing list, and have at least my two I2C busses and the UARTs up & running now (at least they get recognized during boot, even an I2C RTC get probed and read out correctly). Maybe it's of help for somebody else: https://www.mail-archive.com/[email protected]/msg00040.html

I have to figure out why the UART and the PIO behind the bridge are not detected (right now it seem the whole brigde is ignored).
