[U-Boot] U-boot doesn't start

Hi all;

Having installed the ELDK and gitted the latest u-boot I can build it OK. The trouble is after flashing it the ubl will start but not u-boot itself. Reverting to the old u-boot we got from TI on the SDK works just fine but this is 1.2.0 and we wanted the latest version. We are using the DM355 EVM board design with some changes of our own.

Does anyone have any pointers as to what I should do next?

Regards
