MLO doesn't work, rest is ok

[Norbert Roos]

Hello,

I just wanted to try the freshly generated MLO and barebox.bin on my 
Phytec PCM049 board (OMAP4 based). Copied both files to the FAT 
partition on the SD card.

Unfortunately it doesn't boot, after trying to boot from SD card the ROM 
boot loader oviously skips to booting from UART.

When i replace the MLO with a different one (downloaded a compiled one), 
my generated barebox.bin gets loaded and everything's fine.

Is there a simple way for debugging it? It seems like the MLO does not 
get executed, as the ROM boot skips to UART boot...

bye
Norbert
