Hi,
We made a custom board for OMAP3530, we also developed a bootloader. but our memory model is a bit different to logicpd's SOM board.
I made changes in config.bib,

the eboot is executing properly executing, copying the file, and jumping to 0x8400B010, but no more debug messages are coming, i changed the debug.c file for UART3 as our custom board uses uart3 for debug, and I also made changes in platform.c file. the nk.map file some portion included below

so please suggest me where else I need to make changes for properly executing the NK.bin.?

Thanks in Advance,
