I have built big standalone application for similar CPU (at92rm9200). I use some RAM address to do so, namely LOAD_ADDR=0x21000000.
See my make rules below.

Hi all,
I am having problem running the "hello_world" examples that comes with u-boot on ARM926 board.
Board: ARM926 (AB) application baseboard Tools: CodeSourcery (arm-none-linux-gnueabi-)
I manage to build u-boot successfully as follow 1. make versatileab_config CROSS_COMPILE=arm-none-linux-gnueabi- 2. make all CROSS_COMPILE=arm-none-linux-gnueabi- Then i flash "u-boot.bin" into the board memory.
Then i load and run the standalone program "hello_world.bin" as follow
VersatileAB # tftp 0xc100000 hello_world.bin Using MAC Address 00:02:F7:00:10:31 TFTP from server 192.168.1.105; our IP address is 192.168.1.109 Filename 'hello_world.bin'.

ARM Versatile/AB926EJ-S Boot Monitor Version: V2.0.2 Build Date: Apr 12 2005 Endian: Little
I notice the load address 0xc100000 is pointing to reserve area according to User Guide Manual from ARM
Reserved (MPMC Chip Select 1, dynamic expansion memory on Versatile/PB926EJ-S) - - 0x08000000- 0x0FFFFFFF 128MB
Any idea?
Thanks
