Sorry for the delayed response - got called away, but am back to this
now. I patched
socfpga_common.h and re-built the project. I picked up
spl/u-boot-spl-dtb.sfp and
u-boot-dtb.img and transferred them to the SD card with:
dd if=u-boot-spl-dtb.sfp of=/dev/sdf3 bs=64k seek=0
dd if=u-boot-dtb.img of=/dev/sdf3 bs=64k seek=4
Tried this with both the original DT set (socfpga.dtsi, socfpga_cyclone.dtsi,
socfpga_cyclone5_sockit.dts) that came with the u-boot v2016.01 download and
also an Altera-patched DT set that I've used to boot into Linux numerous times.
When I start up the board I get:
U-Boot SPL 2016.01 (Mar 01 2016 - 17:28:14)
drivers/ddr/altera/sequencer.c: Preparing to start memory calibration

### ERROR ### Please RESET the board ###
I'm not a Quartus user, so I haven't done anything with the
qts-filter.sh script you
mentioned. Do I need to? I don't have any custom FPGA logic - it's
just the Terasic
board out of the box.
Thanks for any help!
Even without the custom FPGA logic the files generated from qts-filter.sh need
to match your board.
Sets up PLL and SDRAM parameters.
I'm not familiar with the Terasic dev board ( I do have the altera devkit, but
haven't used it for awhile).
I'd hope the files in the git repo are correct for your board.
Without the corresponding qsys project it's hard to be sure.
The sd card write commands look correct.
I just used a dts files in the uboot source but modified a couple of things.
Update Mem size and serial port speeds to match our requirements.
I also modified a few debug statements so the spl outputs a bit more info by
default.
Output is alot closer to the altera supplied uboot tree.
My spl bootup is:

Marek who committed the terasic config may be able to help.
It most likely a mismatch in the qts config vs hardware.
