Without the patch, the bs partition on the AC Mesh is locked forever. This can be a problem if a) the bs partition has not been updated correctly during initial flash b) the sysupgrade mechanism is altered by OpenWRT in order to account for the flip flop layout Signed-off-by: Adrian Schmutzler Reviewed-by: Fabian Bläse --- ...-remove-bs-partition-ro-flag-for-UniFi-AC.patch | 36 ++++++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 build_patches/openwrt/0031-ar71xx-remove-bs-partition-ro-flag-for-UniFi-AC.patch diff --git a/build_patches/openwrt/0031-ar71xx-remove-bs-partition-ro-flag-for-UniFi-AC.patch b/build_patches/openwrt/0031-ar71xx-remove-bs-partition-ro-flag-for-UniFi-AC.patch new file mode 100644 index 0000000..9814f66 --- /dev/null +++ b/build_patches/openwrt/0031-ar71xx-remove-bs-partition-ro-flag-for-UniFi-AC.patch @@ -0,0 +1,36 @@ +From e873363e0541d8ded05635e8341efe564c5d9cff Mon Sep 17 00:00:00 2001 +From: Adrian Schmutzler +Date: Tue, 10 Apr 2018 19:04:13 +0200 +Subject: [PATCH] ar71xx: remove bs-partition ro-flag for UniFi AC + +This removes the read-only flag from the bs (bootselect) partition +on UniFi AC devices.
