Hello all, A while back i have created a ticket (https://dev.openwrt.org/ticket/17609) detailing kernel 3.14.x failure to boot on ar71xx (wndr3700v4 router) platform. Today i have successfully used serial console attached to the router and got a boot log which shows a wrong checksum of kernel image when trying to attach it from UBI to MTD, please see output below ... i hope this helps in identifying and narrows the issue for a possible fix.
Cheers!
