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.
