Hi Mikhail,
I am using ELDK 4.2 and U-Boot 2009.03 on an EP88xC rev1.1 board (MPC885 cpu) and am trying to get the example apps working (the ones that come with U-Boot) following instructions on "http://www.denx.de/wiki/view/DULG/UBootStandalone#Section_5.12.2.".
"examples/hello_world.bin" worked fine:
[...]
But things didn't go too smoothly with the "examples/timer.bin" app:
=> tftp 40000 ep88x_timerdemo Trying FEC ETHERNET Using FEC ETHERNET device TFTP from server 10.0.54.129; our IP address is 10.0.54.150 Filename 'ep88x_timerdemo'. Load address: 0x40000 Loading: ################## done Bytes transferred = 263740 (4063c hex) => go 40004 ## Starting application at 0x00040004 ...
Oh huh - this would imply that the "timer" routine got linked to this address. When I use objdump to deassemble the object file, it seems that "timer" is at 40108. Try "go 0x40108" and read the FAQ[1] ;)
Cheers Detlev
