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:

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 COLLECT_LTO_WRAPPER=/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/4.9.3/lto-wrapper < snip >
Any advice greatly appreciated.

Rebuilt using the Altera EDS15.0 toolchain:

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
