From: Christoph Krapp Date: Mon, 14 Apr 2025 18:47:56 +0000 (+0200) Subject: mediatek: filogic: add support for ASUS RT-AX52 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7d6f98c0d4062c0ded8b5fa423941eeae35e9a10;p=openwrt%2Fstaging%2Fblocktrron.git mediatek: filogic: add support for ASUS RT-AX52 Hardware -------- SOC: MediaTek MT7981b RAM: 256MB DDR3 FLASH: 128MB SPI-NAND (Winbond W25N01GV) WIFI: Mediatek MT7981b DBDC 802.11ax 2.4/5 GHz ETH: MediaTek MT7531 Switch UART: 3V3 115200 8N1 (Pinout silkscreened / Do not connect VCC) Installation ----------------------------------------------------------- Vendor-UI Method ----------------------------------------------------------- 1. Download the OpenWrt initramfs.trx image. 2. Connect the PC via LAN to one of the yellow router ports and wait until your PC to get a DHCP lease. 3. Browse to http://192.168.50.1 4. If your router is brand new, finish the setup process and log into the Web-UI. 5. Navigate to Administration -> Firmware Upgrade and upload the downloaded OpenWrt image. 6. Wait for OpenWrt to boot. Transfer the sysupgrade image to the device using scp and install using sysupgrade. $ sysupgrade -n ----------------------------------------------------------- TFTP Method ----------------------------------------------------------- 1. Download the OpenWrt initramfs image. Copy the image to a TFTP server reachable at 192.168.1.70/24. Rename the image to rtax52.bin. 2. Connect the PC with TFTP server to the RT-AX52. Set a static ip on the ethernet interface of your PC. (ip address: 192.168.1.70, subnet mask:255.255.255.0) Conect to the serial console, interrupt the autoboot process by pressing '4' when prompted. 3. Download & Boot the OpenWrt initramfs image. $ setenv ipaddr 192.168.1.1 $ setenv serverip 192.168.1.70 $ tftpboot 0x46000000 rtax52.bin $ bootm 0x46000000 4. Wait for OpenWrt to boot. Transfer the sysupgrade image to the device using scp and install using sysupgrade. $ sysupgrade -n ---------------------------------------------------------------------------------- Revert to stock firmware: 1: Download the rt-ax52 firmware from ASUS official website. Save the firmware to tftp server directory and rename to RT-AX52.trx 2: Connect the PC with TFTP server to the RT-AX52. Set a static ip on the ethernet interface of your PC. (ip address: 192.168.1.70, subnet mask:255.255.255.0) 3: Conect to the serial console, power on again, interrupt the autoboot process by pressing '4' when prompted. $: ubi remove linux $: ubi remove jffs2 $: ubi remove rootfs $: ubi remove rootfs_data $: ubi create linux 0x45fe000 $: reset then the dut will reboot,interrupt the autoboot process by pressing '2' when prompted. 2: Load System code then write to Flash via TFTP. Warning!! Erase Linux in Flash then burn new one. Are you sure?(Y/N) $: enter y you will see the follow, type enter directly: Input device IP (192.168.1.1) ==: Input server IP (192.168.1.70) ==: Input Linux Kernel filename (RT-AX52.trx) ==: 4: wait for the device run up (based on support for ASUS RT-AX52 by liudongdongdong7397 and trx image generation by remittor) Signed-off-by: Christoph Krapp --- diff --git a/target/linux/mediatek/dts/mt7981b-asus-rt-ax52.dts b/target/linux/mediatek/dts/mt7981b-asus-rt-ax52.dts new file mode 100644 index 0000000000..7f4926b493 --- /dev/null +++ b/target/linux/mediatek/dts/mt7981b-asus-rt-ax52.dts @@ -0,0 +1,301 @@ +// SPDX-License-Identifier: GPL-2.0-or-later OR MIT +/dts-v1/;
