From 52f2d7d2a9dc3e142bb957462a30806eb5cebaf4 Mon Sep 17 00:00:00 2001 From: Anton Arapov Date: Sat, 29 Dec 2018 01:28:27 +0100 Subject: [PATCH] ramips: add RB750Gr3 native support MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This patch adds support of MikroTik RouterBOARD 750Gr3, without the need to reflashing the bootloader. Installation through RouterBoot follows the usual MikroTik method https://openwrt.org/toh/mikrotik/common Since the image isn't compatible with RouterBOARD 750Gr3 installations which have replaced the bootloader, the former used userspace boardname is not added to the SUPPORTED_DEVICES, to prevent a brick while trying to upgrade to the image with native support.
