I have started ubuntu14.04.1 on the board through i.MX6q SABRE Board for Smart Devices - Linux on ARM - eewiki ,all the things needed are in the SD card.Now i want to start the linux kernel through TFTP and access the rootfs on the host via NFS.Through the first way I got the image file named zImage and the rootfs supposed it named ubuntu14.04.1. I have put them in the TFTP shared directory and NFS shared directory in the host.Then I should set the parameters on the UBOOT command line which has done as follow:
setenv ipaddr <myipaddr>
setenv serverip <my serverip>
setenv gatewayip <my gatewayip>
setenv ehtaddr <my ethaddr>
setenv ip_dyn no
setenv nfsroot /home/nfs
setenv image zImage
setenv loadaddr 0x12000000
ok,the problem is that,I don't know how to set the remaining parameters such as bootargs,bootcmd or more else……
And I want to know if the image and the rootfs I used are correct, if not ,can someone provide me a correct one?
Thanks a lot .
