From 820f0c07c544652c1c53a45262a481ac5dbe139b Mon Sep 17 00:00:00 2001 From: Sven Wegener Date: Sat, 1 May 2021 13:51:51 +0200 Subject: [PATCH] ramips: add support for Ubiquiti UniFi FlexHD Hardware -------- - SoC: MediaTek MT7621AT with 128 MiB RAM and 32 MiB Flash - Wi-Fi: MediaTek MT7603 (b/g/n, 2x2) and MediaTek MT7615 (ac, 4x4) - Bluetooth: CSR8811 (internal USB, install kmod-bluetooth) Installation ------------ 1. Connect to the booted device at 192.168.1.20 using username/password "ubnt". 2. Update the bootloader environment. $ fw_setenv devmode TRUE $ fw_setenv boot_openwrt "fdt addr \$(fdtcontroladdr); fdt rm /signature; bootubnt" $ fw_setenv bootcmd "run boot_openwrt" 3. Transfer the OpenWrt sysupgrade image to the device using SCP. 4. Check the mtd partition number for bs / kernel0 / kernel1 $ cat /proc/mtd 5. Set the bootselect flag to boot from kernel0 $ dd if=/dev/zero bs=1 count=1 of=/dev/mtdblock4 6. Write the OpenWrt sysupgrade image to both kernel0 as well as kernel1 $ dd if=openwrt.bin of=/dev/mtdblock6 $ dd if=openwrt.bin of=/dev/mtdblock7 7. Reboot the device. It should boot into OpenWrt.
