Hi Tom,

Sorry to keep bugging you today.

I was just informed by one of my colleagues that there are another ti uboot git tree

So out of these three: [1] http://git.omapzoom.org/?p=repo/u-boot.git;a=shortlog;h=refs/heads/p-ti-u-bo... [2] http://git.ti.com/ti-u-boot/ti-u-boot/commits/ti-u-boot-2013.10 [3] denx's master

Which one should we use if we want to get as close to mainline with dra7xx_evm capable of booting from eMMC in RAW mode?

Our eval platform comes with sources from [1] and boots all the way to the linux. The ones built from [2] or [3] are not booting into the linux in the uSD.

it errors out like this:

U-Boot 2013.10-00095-g996f0c4 (Nov 21 2013 - 19:53:47)

If it is a matter of porting some patches, we are willing to help test and mainline if it means we can get denx-master for dra7xx working.

So, from the log above I assume that's the ti-u-boot-2013.10 tree, as that as SATA patches that will be merged into mainline soon. From the [1] tree, stop the boot process and printenv bootcmd, and copy that info over (or see what their include/configs/dra7xx_evm.h says the bootcmd is) as the error you show is just that the default location for the kernel isn't correct with the Android rootfs you're using. Mainline also doesn't have CONFIG_EFI_PARTITION set which is why it can't read the partition table. That's an easy patch to make and post :)
