Hello, 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: => tftp 40000 ep88x_helloworld Trying FEC ETHERNET Using FEC ETHERNET device TFTP from server 10.0.54.129; our IP address is 10.0.54.150 Filename 'ep88x_helloworld'.
