Use uEnv.txt for Testing (19 replies)

My Pogo server have run on the NFS for more than 1 year, and I never worry about the lifespan of the SD card. An old IDE hard disk is attached to the Openwrt router by USB 2.0 and provide a stable rootfs for the Pogo.
Several months ago I got a new ASUS-merlin router, I am going to move the rootfs to the new one. This time, I'll try using uEnv.txt to test the NFS booting.

I put all tsunulukai's envs in uEnv.txt

run bootcmd_uenv
