UniBoard2 first blinking LED

Submitter: Sjouke Zwier & Gijs Schoonderbeek
Description: On the 21st of May we saw what we have been looking forward to for almost 2 years: a blinking LED on UniBoard2!

To reach this milestone, we had to choose an architecture, draw a schematic and layout, check and re-check, revise and review...

At the beginning of May all 5600 components had arrived at Neways Leeuwarden, ready to be soldered on to the board. On the 13th of May UniBoard2 arrived at the lab and it was time for the nerve-wracking first power-up. After some small modifications (only a couple of the 20000 connections had to be changed), we had a successful power-up of all parts on UniBoard2. With a boundary scan test all input and output connections to the FPGAs were checked for correct soldering. Now the board was ready to be programmed with firmware to blink the LEDs. This is illustrated in the image.

The next step is to test the remaining FPGA interfaces, including DDR4 memory and some 384 ten gigabit transceivers. Reaching this point was a collaborative effort of the RadioNet3 UniBoard2 Joint Research Activity (JRA) partners, and with companies like Neways and QPI.
