HI,
I have my bootloader running and i get the boot prompt. Now i am trying to load hello_world.bin and trying to execute it. 1>> I have a pxa250 (ARM)processor on Accelent board. As per Readme.Standalone i should be loading the application at 0x0c100000 and executing from the same address.But no where in the hello_world.c i find any link which tells the application that it should stick to the above specified address. Then why is it that U-boot can run the application only if it is at that address. I read some previous posts which say that we can download the application anywhere other than 0x0c100000,but u boot wont execute them. Why is it so? Where has it been specified that u-boot should execute standalone application only if it is at that address
2>>The memory map for pxa250 which i received says nCS0: 0x00000000-0x03ffffff
J77 1-2 Flash ROM (default) J78 2-3 M-Systems Disk On Chip
nCS1: 0x04000000-0x07ffffff
J78 1-2 M-Systems Disk On Chip (default) J77 2-3 Flash ROM
nCS2: 0x08000000-0x0bffffff
Unused, available on expansion buses
nCS3: 0x0c000000-0x0fffffff
J49 1-2: MediaQ MQ1132 J49 open: Unused, available on expansion buses
which means address space 0x0c000000-0x0fffffff is unused. Then how can i download my application to that address and execute it.
