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

<br>- Network configuration is Ok. <br>- Network card is OK. In u-boot env, i use tftp to load kernel image and ramdisk image ==> network card is ok<br>- In kernel with patched, i think kernel image had driver for network card (
