Hummingboard u-boot not loading?

[Russell Haley]

Hello,

Recap: I'm trying to get a Hummingboard with dual core pro SOM to boot
using only HDMI output (I don't have a FTDI cable yet) . I am running a
binary u-boot from Oleksandr. Successfullly built head yesterday.

My SD Card looks like this:

- 1Mb free space with uboot at 1k
- 50Mb Fat32 partition with ubldr
- 3.6Gb ufs partition

I applied the patch for HDMI output:
https://lists.freebsd.org/pipermail/freebsd-arm/2015-July/011912.html
(Oleksandr via Mikael).  I then ran  buildkernel with the -DNOCLEAN option
(thanks Ian!). I then mistakenly did a installkernel which takes hours on
an SD card and overwrote everything so I couldn't tell if the files I
wanted were actually installed (i.e. imx6_hdmi.o). I can't find any of the
files I think I should have been added, but that could be my feeble
understanding of file searching.

Anyway, I ran it and nothing changed. I get a u-boot auto config counting
down, I get the message *20647 bytes read in 26 ms (9.6MiB/s) *which is the
size of ubldr, but nothing fires after that. It could the output is
happening on a serial out, or it could be nothing is happening??? I have
toyed with the idea of adding something to loarder.conf, but the defaults
all seem sufficient, again, unless someone can suggest something?

I have no further actions I can think of until I get an FDTI cable. All
suggestions welcome.

Russ
