I have ported uboot-2013R1 on my custom board, for network, it can detect the LAN9218 controller ,phy correctly initialized and the MAC address is initialized form the configuration file. so next step, I plan to port buildroot-2013r1c1 on my board, and I have compiled it successfully for I can run tftp to load uImage to the ram with no crashes .
when I use the ping or ifconfig eth0 up ,it fails on uclinux ,the kernel said : device eth0 not found .I compared the MAC address with the one in uboot,but they differs ,Is this the reason? For another difference, the driver for the lan controller in uboot and uclinux differs .
Can anybody give some suggestions?
By the way , I attached the startup inforamtion both in my uboot and uclinux.
