Hello again -
So under the assumption my SoCKit h/w was broken, I bought a new board.
They are back ordered on SoCKit boards, so I got a DE0-Nano-SoC instead.
I build the v2016.03 (release) version of u-boot-with-spl.sfp.
I power-up the (brand new) board and get:
U-Boot SPL 2016.03 (Mar 15 2016 - 14:52:42)
drivers/ddr/altera/sequencer.c: Preparing to start memory calibration

And this is a good case... usually it doesn't succeed after the fourth try
and I have to cycle power 4 or 5 times before I get lucky.
If I do get lucky and then try to see a USB storage device, then I get:

(Every time)
The version of u-boot SPL that ships with the board:
U-Boot SPL 2013.01.01 (Dec 29 2014 - 15:29:15)
boots every time and has limited USB capability as
it can see some USB sticks, but not others.
Anyway - brand new board - same old symptoms.
Is it perhaps a toolchain problem?? I'm using:
Thread model: posix
gcc version 4.9.3 20141031 (prerelease) (Linaro GCC 4.9-2014.11)
COLLECT_GCC=arm-poky-linux-gnueabi-gcc

< snip >
Any advice greatly appreciated.

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...

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.
