On an AM335x board I had problems when moving from embedded to separate
DTB. Even if deprecated you should probably give CONFIG_OF_EMBED a try.
If this works you could go back to CONFIG_OF_SEPARATE and probably give
CONFIG_SPL_SEPARATE_BSS a try.
Also CONFIG_DEBUG_UART (assumed the pin configuration is working) did
help me quite a lot.
