mediatek: add support for netis NX31 This PR adds support for netis NX31 router. Specification ------------- - SoC  : MediaTek MT7981BA dual-core ARM Cortex-A53 1.3 GHz - RAM  : 256 MiB DDR3 - Flash  : SPI-NAND 128 MiB (ESMT) - WLAN  : MediaTek MT7976CN dual-band WiFi 6 - 2.4 GHz : b/g/n/ax, MIMO 2x2 - 5 GHz  : a/n/ac/ax, MIMO 2x2 - Ethernet  : 10/100/1000 Mbps x3 (LAN, MediaTek MT7531AE) 10/100/1000 Mbps x1 (WAN, SoC internal phy) - USB  : No - Buttons  : Mesh, Reset - LEDs  : 1x Power (blue), unmanaged 1x Status (blue), gpio-controlled 1x WiFi 2.4 GHz (blue), gpio-controlled 1x WiFi 5 GHz (blue), gpio-controlled 3x LAN activity (blue), switch-controlled 1x WAN activity (blue), gpio-controlled - Power  : 12 VDC, 1 A Installation ------------ 1. Connect to the router using ssh (user: admin, pass: web interface password) 2. Make mtd backup: cat /dev/mtd0 | gzip -1 -c > /tmp/mtd0_spi0.0.bin.gz cat /dev/mtd1 | gzip -1 -c > /tmp/mtd1_BL2.bin.gz cat /dev/mtd2 | gzip -1 -c > /tmp/mtd2_u-boot-env.bin.gz cat /dev/mtd3 | gzip -1 -c > /tmp/mtd3_Factory.bin.gz cat /dev/mtd4 | gzip -1 -c > /tmp/mtd4_FIP.bin.gz cat /dev/mtd5 | gzip -1 -c > /tmp/mtd5_ubi.bin.gz 3. Download mtd backup from the /tmp dir of the router to your PC using scp protocol 4. Upload OpenWrt 'bl31-uboot.fip', 'preloader.bin' images to the /tmp dir of the router using scp protocol 5. Write FIP and BL2 (replace bootloader): mtd write /tmp/openwrt-mediatek-filogic-netis_nx31-bl31-uboot.fip FIP mtd write /tmp/openwrt-mediatek-filogic-netis_nx31-preloader.bin BL2 6. Place OpenWrt 'openwrt-mediatek-filogic-netis_nx31-initramfs-recovery.itb' image on the tftp server (IP: 192.168.1.254) 7. Erase 'ubi' partition and reboot the router: mtd erase ubi reboot 8. U-Boot automatically boot OpenWrt recovery image from tftp server to the RAM 9. Upload OpenWrt 'sysupgrade.itb' image to the /tmp dir of the router (IP: 192.168.1.1) using scp protocol 10. Connect to the router using ssh and run: sysupgrade -n openwrt-mediatek-filogic-netis_nx31-squashfs-sysupgrade.itb Return to stock --------------- 1. Unpack stock BL2 and FIP partitions backup 2. Upload stock BL2 and FIP partitions backup to the /tmp dir of the router using scp protocol 3. Connect to the router using ssh and run: apk update && apk add kmod-mtd-rw insmod mtd-rw i_want_a_brick=1 mtd unlock BL2 mtd unlock FIP 4. Restore backup: mtd write /tmp/mtd4_FIP.bin FIP mtd write /tmp/mtd1_BL2.bin BL2 5. Erase ubi and reboot: mtd erase ubi reboot 6. Power off the router 7. Press Reset button and power on the router. Release the button after ~10 sec 8. Navigate to U-Boot recovery web server (http://192.168.1.1/) and upload the OEM firmware Recovery -------- 1. Place OpenWrt 'openwrt-mediatek-filogic-netis_nx31-initramfs-recovery.itb' image on the tftp server (IP: 192.168.1.254) 2. Press “Reset” button and power on the router. After ~10 sec release the button. 3. Use OpenWrt initramfs system for recovery MAC addresses ------------- +---------+-------------------+-----------+ | | MAC | Algorithm | +---------+-------------------+-----------+ | LAN | dc:xx:xx:d1:xx:18 | label | | WAN | dc:xx:xx:d1:xx:1a | label+2 | | WLAN 2g | de:xx:xx:11:xx:19 | | | WLAN 5g | de:xx:xx:71:xx:19 | | +---------+-------------------+-----------+ The LAN MAC was found in 'Factory', 0x1fef20 The WAN MAC was found in 'Factory', 0x1fef26 The WLAN 2g/5g MAC prototype was found in 'Factory', 0x4 Signed-off-by: Mikhail Zhilkin <csharper2005@gmail.com> Link: https://github.com/openwrt/openwrt/pull/18324 Signed-off-by: Hauke Mehrtens
