I am using BDI2000 with my at91rm9200 board - I think, you can do the same for at91rm9263 unless you doesn't get JTAG on your board. I can step through code, etc...

Does anyone have a recipe for debugging u-boot on AT91SAM9263-EK target?
Our proprietary board is very similar, but can't see what goes wrong. Atmel has a bootstrap that inits SDRAM, and loads u-boot image from Flash device into SDRAM. It jumps to the proper address in the SDRAM and dies.
All we have to debug is J-Link from Segger along gdbserver from Segger which is an application that runs on Windows and talks via Usb to the J-Link Pod. We can talk to Windows as if it were gdbserver from a Linux host.
The bootup sequence provided by Atmel looks different from u-boot in that u-boot does not move itself into SDRAM, this is done by the Atmel bootstrap.
Don't know how to init SDRAM from J-Link. Has anyone done that?
