Get same result ... mostly failing calibration, non-working USB....

Does this work for anybody else? Is it in anyone's experience that these (cheaper) Terasic eval boards are generally out of spec?
Is there a way to relax the calibration parameters? the USB parameters?
Would it help if I posted debug output?
Sorry for the late reply, I am horribly overloaded now. I asked someone in #u-boot who has the DE0-NANO-SOC board to test latest u-boot/master on it and it apparently worked for him. I should get some more feedback in the morning [ see http://pastebin.com/CM1QJGnh ] .
Still, this is getting real creepy. You are the second person who is complaining about misbehavior of terasic boards with mainline u-boot and whatever I do, I cannot replicate this.
I am at least CCing the Altera guys. Sorry I have no better suggestion for you :(
Best regards, Marek Vasut
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.
Try "dcache off" before "usb reset", I had trouble with usb in recent versions due to cache problems. If this works, I am happy to give you a workaround, but I would also love a real solution ... which I do not have for 3+ months now :'-(
Best regards, Marek Vasut
Thanks, but nope - same story: => dcache off => dcache Data (writethrough) Cache is OFF => usb reset resetting USB... USB0: Core Release: 0.000 SNPSID invalid (not DWC2 OTG device): 00000000 Port not available. USB1: Core Release: 2.93a dwc_otg_core_host_init: Timeout! dwc_otg_core_host_init: Timeout! dwc_otg_core_host_init: Timeout! dwc_otg_core_host_init: Timeout! ... : :
USB worked on my board for 2016.1 Don't think I did anything special. Testing was limited, could see files on the USB partition etc.
Ther are some sticks which trigger an USB issue, but it's more of an issue in the cache configuration than the USB controller itself I think.
