Hi Marek,

I've got a third board coming to me in the mail (another
DE0-NANO-SOC). I'll post
how that goes.If it fails, maybe I'll send it to you...

I've also sent Terasic an email.

One question - after you (your collegue's) SoCKit (Nano) get past memory
calibration, does USB work (i.e. does the u-boot USB subsystem recognize mass
storage devices)?

I'm beginning to look for solutions that don't involve rebuilding the
SPL or using USB.

Best regards,
