Hi all
I have two de10-nano boards, one is working and the other isn't. I've tested it with several sdcards, but of course also
with the one that actually runs fine. Installations i've tried are mr fusion (2.9,2.8,2.3)
Hooking up a uart, i get the following messages:
A: with a working sdcard (from the other system)
U-Boot SPL 2017.03+ (Dec 24 2022 - 15:55:06)
drivers/ddr/altera/sequencer.c: CALIBRATION FAILED
SDRAM calibration failed.
ERROR ### Please RESET the board
B: with a fresh sdcard, which I accidentally got semi/past the initial installation procedure.
