This repository tracks the code from the TI DVSDK psp/flash-utils directory which contains (among other things) the source code to the UBL bootloader.

Make sure that the CodeSourcery ARM compiler is in the path.

cd DM36x/GNU/ubl make

The file ubl_DM36x_dm365sdmmc.bin will be created. Supposing everything works, this should be a good UBL bootloader that can be written to an SDCard and booted from. See the u-boot project for writing the UBL and U-boot to an SDCard.

If TI updates their DVSDK, it may be nice to update the UBL if they fixed something good or moved some initialization from u-boot or later to the UBL. It is probably easiest to branch off the initial comment, apply TI's updates, and then merge back to master.
