From 0dc8ef6480ee2d508e8891b9f1c1bc1b966aae66 Mon Sep 17 00:00:00 2001 From: Stefan Lippers-Hollmann Date: Fri, 18 May 2018 03:10:18 +0200 Subject: [PATCH] ipq806x: increase kernel partition size for the TP-Link Archer C2600 The default image does not fit 2 MB anymore, expand os-image partition to 4 MB. Upgrading works transparently via sysupgrade in both directions. Another option would have been to merge "os-image" and "rootfs" into a single "firmware" partition using MTD_SPLIT_TPLINK_FW, but just changing the sizes of the existing partitioning has been deemed safer and actually tested on an affected device; the maximum for rootfs changes from 27 MB to 25 MB. Run-tested on TP-Link Archer C2600.
