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 <path-to-sysupgrade.bin>
-----------------------------------------------------------
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 <path-to-sysupgrade.bin>
---------------------------------------------------------------------------
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
