Hi all,
I am having problem running the "hello_world" examples that comes with u-boot on ARM926 board.
---snip
Then i load and run the standalone program "hello_world.bin" as follow
VersatileAB # tftp 0xc100000 hello_world.bin Using MAC
How did you come to choose 0xc1000000 - which as you say is Reserved?
Unless you have modified your AB accordingly you must expect problems using a reserved address....
Try somewhere in SDRAM 0x000000 - 0x07FFFFFF (depending on your switch settings) as per your manual
Regards
Peter
