mediatek: add support for Mercusys MR85X
This commit adds support for Mercusys MR85X router.
Device specification:
- SoC: Mediatek MT7981b, Cortex-A53, 64-bit
- RAM: 512MB
- Flash: SPI NAND GigaDevice GD5F1GQ5UEYIGY (128 MB)
- Ethernet: Realtek rtl8367s + 2.5Gbe Airoha en8811h
- Ethernet: 1x2.5Gbe (WAN 2.5Gbps), 3xGbe (LAN 1Gbps, port0, port1, port2)
- Wireless: 2.4GHz (802.11 b/g/n/ax)
- Wireless: 5GHz (802.11 a/n/ac/ax)
- LEDs: 1 amber and 1 green status LEDs, 4 green gpio-controlled LEDs
on ethernet ports
- Buttons: 2 (reset,wps)
- Bootloader: Main U-Boot - U-Boot 2022.07-rc3. Additionally, both UBI
slots contain "seconduboot" (also U-Boot 2022.07-rc3)
Installation (UART):
- Place OpenWrt initramfs-kernel image on tftp server with IP 192.168.1.2
- Attach UART, switch on the router and interrupt the boot process by
pressing 'Ctrl-C'.
- Set the uboot environment for startup.
setenv tp_boot_idx 0; saveenv
If the bootarg is set to boot from ubi1, also change it to ubi0.
- Load and run OpenWrt initramfs image.
setenv serverip 192.168.1.2; setenv ipaddr 192.168.1.1; tftpboot initramfs-kernel.bin; bootm
- Browse IP 192.168.1.1, upload the 'sysupgrade' image and do upgrade.
Recovery:
- Press Reset button and power on the router.
- Navigate to U-Boot recovery web server (http://192.168.1.1/) and
upload the OEM firmware.
Stock layout:
0x000000000000-0x000000200000 : "boot"
0x000000200000-0x000000300000 : "u-boot-env"
0x000000300000-0x000003500000 : "ubi0"
0x000003500000-0x000006700000 : "ubi1"
0x000006700000-0x000006f00000 : "userconfig"
0x000006f00000-0x000007300000 : "tp_data"
ubi0/ubi1 format:
U-Boot at boot checks that all volumes are in place:
+-------------------------------+
| Volume Name: uboot Vol ID: 0|
| Volume Name: kernel Vol ID: 1|
| Volume Name: rootfs Vol ID: 2|
+-------------------------------+
MAC addresses:
+---------+-------------------+-----------+
| | MAC | Algorithm |
+---------+-------------------+-----------+
| label | 00:FF:xx:xx:xx:EE | label |
| WAN | 00:FF:xx:xx:xx:EF | label+1 |
| LAN | 00:FF:xx:xx:xx:EE | label |
| WLAN 2g | 00:FF:xx:xx:xx:ED | label-1 |
| WLAN 5g | 00:FF:xx:xx:xx:EC | label-2 |
+---------+-------------------+-----------+
label MAC address was found in UBI partition "tp_data", file "default-mac".
OEM wireless eeprom is also there, file "MT7981_EEPROM.bin".
