Dear All ,

I am working on AT91SAM9263 Customised board having U-boot. I want to rn some application on the top of U-boot . I found some command like go to run a application in U-boot. I m trying to run the demo program Hello_world.c provided in the U-Boot source . But after loading that to 0x40000 addresss and executing from 0x40004 address (according to the U-Boot manual) it is not Giving proper Output . Plz any one help me How can I run a stand alone program in U-Boot ?

Regds,
