 How do you debug code on this board?  What gdb setup?  BDM, stub, etc?

+Using a different emulator (fork), and running a different u-boot, emulating a beagleboard xm, this hello world also works on the bbxm. The bbxm has no internal NAND so booting is a bit different, the mmc card is needed. the image referenced contains a FAT partition that contains hello.img:
+
+  $ qemu-system-arm -M beaglexm -drive if=sd,cache=writeback,file=rtems_arm_sd.img -clock unix -serial stdio
+
+booting then looks like:
+
+  OMAP3 beagleboard.org # fatload mmc 0:1 0x80800000 hello.img
+  reading hello.img
+  56548 bytes read in 12 ms (4.5 MiB/s)
+  OMAP3 beagleboard.org # bootm 0x80800000
+  ## Booting kernel from Legacy Image at 80800000 ...

+This means that bbxm support should not be too far off.
