From d700c120bffe806aa23442cbbcce30e1c1886b79 Mon Sep 17 00:00:00 2001 From: Adrian Panella Date: Thu, 8 Dec 2016 02:41:58 -0600 Subject: ipq806x: EA8500 fix sysupgrade over stock firmware When running sysupgrade for the first time over the second partition (that still had stock firmware) the rootfs wasn't flashed as there wasn't enough space. This happend because stock also uses UBI, but the volume name wasn't recognised and wasn't deleted before flashing.
