Does your board have any buttons or DIP-switches to select boot order? You may
need to select the serial boot in order for the BootROM to send a handshake
sequence on the UART3. The handshake on the therminal looks like several
characters of garbage, starting with '40T'. The boot order is selected by a
DIP-switch on OMAP3EVM and by a "User" button on BeagleBoard.
Then you need to use one of the available peripheral loaders to load a small
version of U-boot over UART or USB into OMAP's SRAM and from there you can
flash a final versions of x-load and U-boot into NAND. There are HOWTO's
available, for example, here is one for BeagleBoard:
There should be a similar one for OMAP3EVM, but I currently cannot seem to
