I have my bootloader running and i get the boot prompt.
Now i am trying to load hello_world.bin and trying to
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
J77 1-2 Flash ROM (default)
J78 2-3 M-Systems Disk On Chip
J78 1-2 M-Systems Disk On Chip (default)
J77 2-3 Flash ROM
Unused, available on expansion buses
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.
