[U-Boot-Users] Load/run application

[Chan Queenie-r54684]

Hi,

I have the u-boot running normally on my board.  I downloaded the default hello_world.bin onto the board at memory location 40004.  I can see the data there is correct as it is the same as my .bin file.  However, when I type 
"=> go 40004 Hello World! This is a test."
as instructed in the readme file, a Program Check Exception occurs.  Can anyone tell me why?

I'm attaching the program dump below:
