The boards got manufactured somewhat in a rush so one 301k resistor was missing, had to be hand-soldered. Luckily it was 0402 sized and not 0201, so I did not need to use microscope to replace it. After that heart pumping, pushing in cables from lab supply to power up the board... as I precaution I am used to turn my face away from the victim that is connected to power first time. This time it was boring, power consumption looked good and the inverse LED on the FPGA Done pin did lit as expected.

JTAG or not JTAG that is the question. Pushing in usb-jtag adapter into the 6 zikzak holes next to FPGA. Vivado hardware manager, auto.. JTAG scan success. We are ready...
