Steps to compile and run OpenWRT on Edge Router

Open to access USB drive

Need to open up the Edge Router to access the USB drive. It needs to be . Below is picture after opening it up. Be careful when unplugging the USB drive. Hold on to the USB connector, so that there is not much pull on the connector

Get Source

Clone using

 git://git.openwrt.org/14.07/openwrt.git

Build

From the top dir run “make menuconfig and set target to be Octeon. Pictures showing top dir and Target selection below.

 

Partition

The partition of the USB drive looked like below. I probably had partitioned this before. If it doesn’t look like below, you want to use fdisk to partition the USB drive.

Disk /dev/sdg: 3880 MB, 3880452096 bytes
120 heads, 62 sectors/track, 1018 cylinders, total 7579008 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
Disk identifier: 0xe9ad0200
Device Boot Start End Blocks Id System 
/dev/sdg1 2048 292863 145408 c W95 FAT32 (LBA)
/dev/sdg2 292864 3710975 1709056 83 Linux

Images

After the build completes there will be image in in ./bin/octeon directory.

cp kernel  /media/venkat/0243-8F11/vmlinux

Copy the kernel to the first partition

cp kernel  /media/venkat/0243-8F11/vmlinux

Extract rootfs to the second partition. Be very careful hre and choose the right drive and partition for of

sudo dd if=./root of=/dev/sdg2 bs=1M

Plugin in the USB and boot.
