Has anyone successfully used the sysutils/u-boot-beaglebone port?
I managed to build [1] and install it today. I tried to install it to =
the SD card FAT partition, as per the README, and the result was an =
unbootable system.
When I copied the u-boot.img file as u-boot.img (rather than the =
bb-uboot.img as suggested in the README), I got it to start up to the =
"U-Boot#" prompt. However, it complained about not being able to load =
ubldr.
There isn't a ubldr installed by the u-boot-beaglebone port, so I copied =
the version from /boot/ubldr to the FAT partition. That got it a little =
bit further, but now it hangs after reading ubldr. This is what I get:

After a while, I guess the watchdog kicks in and the whole cycle =
repeats.
I guess I can always restore the FAT partition to its original state, =
but it would be nice to know how to use the u-boot-beaglebone port files =
now I have them.
Cheers,
Paul.
[1] It required removing "CPUTYPE?=3Dnative" from my make.conf before =
devel/arm-none-eabi-gcc would build.=
