Hello All
Hoping somebody can help me out here.
When i tried to download and run the example standalone application 'hello_world' from u-boot, it failed.
I was using 'cutecom' under VMWare to communicate with the target board. I tried use 'loads', at time of '## Ready for S-Record download ...' appeared, i picked up 'hello_world.srec' to send. The console has shown the file transfer success. But no any reply from the board .
I also tried Hyper-terminal, using 'loadb 40000' to download the 'hello_world.bin' to address 0x40000, same thing. But i found out, 'loadb' works when target address set to higher address, such as 0x40000000. But the hello-world application cannot be executed there.
What i did wrong?

then,you could run again
Perhaps address area, used for application load is not suitable / correct. Please look at U-boot environment to define
where (Linux ) kernel is intended to be loaded - in order to define addresses for applications.
Hi, Nuhin:
When I tried load to offset 80000000, like this,
loads 80000000
## Ready for S-Record download ...
## First Load Addr = 0x8C100000
## Last Load Addr = 0x8C100251
## Total Size = 0x00000252 = 594 Bytes
## Start Addr = 0x0C100000
it shows the appllication loaded to 0x8c100000. when i run it by command.
## go 8c100000 test run
the uboot die. no response any more, i have to do a hardware reset.
Any clue?
Thanks!
