This is definitely NOT what you want to use when somebody mentions "latest version". This term always refers to top of tree in mainline U-Boot, see http://git.denx.de/?p=u-boot.git;a=summary resp. git://git.denx.de/u-boot.git
Thank you for that. There is some outdated info here:
"Upstream U-Boot(the one you can download from www.denx.de)'s SPL support doesn't include the AM33XX chip, which is the one used in the Beaglebone. Progress is being done as of December 2011 to get it included. For this reason, we'll use a patched U-Boot provided from TI."

I did:
git clone git://git.denx.de/u-boot.git cd u-boot make am335x_evm_config make cp MLO /boot cp u-boot.img /boot
but I get the following at boot followed by the u-boot command line prompt:
Loaded environment from uEnv.txt Importing environment from mmc ... Loading file "/boot/uImage" from mmc device 0:2 ** File not found /boot/uImage ext2load - load binary file from a Ext2 filesystem
It seems like u-boot is missing the kernel commandline:
# cat /proc/cmdline console=ttyO0,115200n8 ip=none root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait
I tried adding the following to uEnv.txt with no luck:
bootargs="console=ttyO0,115200n8 ip=none root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait"
Can you see what I'm doing wrong?
