Hi everybody!
My board use chip at91rm9200 ( my board as same as ARM9 SBC board http://www.ime.usp.br/~fr/sbc/ ) , and I use u-boot as a boot loader for my system. I built linux image 2.6 ( 2.6.16, 2.6.17, 2.6.18 ) with patch from http://maxim.org.za/AT91RM9200/2.6/ and a small root filesystem and use u-boot to load them. Everything is ok. My system had a sh shell.

But really, it can't connect to outside. ping localhost and it's ip address are ok, but ping a host in LAN ==> false! - Network configuration is Ok. - Network card is OK. In u-boot env, i use tftp to load kernel image and ramdisk image ==> network card is ok - In kernel with patched, i think kernel image had driver for network card ( eth0: Intel LXT971A PHY ).
Can you give me some suggestion. Thanks!!!
