unable to mount roootfs through NFS on imx6 sabre-SD board

stephendcunha · ‎02-11-2014

hi,

I am using the demo images from freescale which is L3.0.35_4.0.0_130424_images_MX6. I am booting through tftp/nfs server and i have also set up a dhcp server.

I am able to load the kernel image through tftp but unable to load the rootfs as the boot hangs at "eth0: Freescale FEC PHY driver [Generic PHY] (mii_bus:phy_addr=1:01, irq=-1)". I have followed all the steps from i.MX_6Dual6Quad_Sabre-SD_Linux_User_Guide. I have provided all my configurations below.

DHCP server setting:

subnet 10.9.211.0 netmask 255.255.255.0 {

option routers 10.9.211.254;

option subnet-mask 255.255.255.0;

option domain-name-servers 10.9.211.11;

host imx6q { hardware ethernet 00:01:02:03:04:05;

fixed-address 10.9.211.30;

option root-path "/tools/rootfs";

option host-name "imx6q";

next-server 10.9.211.11;

filename "uImage";

}
