FYI

I've just spend some time trying to update the spl / uboot / kernel & rootfs image on our
Altera socdk to use for some software testing / development.
Unfortunately it fails in the mem calibration process with the latest uboot most of the time.
And when it does boot somtimes fails loading uboot fomr the mmc.

Our own design works fine.

I've built different images using the qts files in uboot git and those generated from quartus for the socdk.

Both have the same reliability.

It's an old revC board.

Been running perfectly for months using the older spl / uboot. :(
