mediatek: filogic: add support for Xiaomi WR30U
Hardware specification:
SoC: MediaTek MT7981B 2x A53
Flash: ESMT F50L1G41LB 128MB
RAM: NT52B128M16JR-FL 256MB
Ethernet: 4x 10/100/1000 Mbps
Switch: MediaTek MT7531AE
WiFi: MediaTek MT7976C
Button: Reset, Mesh
Power: DC 12V 1A
Flash instructions:
1. Get ssh access
Check this link: https://forum.openwrt.org/t/openwrt-support-for-xiaomi-ax3000ne/153769/22
2. Backup import partitions
```
dev: size erasesize name
mtd1: 00100000 00020000 "BL2"
mtd2: 00040000 00020000 "Nvram"
mtd3: 00040000 00020000 "Bdata"
mtd4: 00200000 00020000 "Factory"
mtd5: 00200000 00020000 "FIP"
mtd8: 02200000 00020000 "ubi"
mtd9: 02200000 00020000 "ubi1"
mtd12: 00040000 00020000 "KF"
```
Use these commands blow to backup your stock partitions.
```
nanddump -f /tmp/BL2.bin /dev/mtd1
nanddump -f /tmp/Nvram.bin /dev/mtd2
nanddump -f /tmp/Bdata.bin /dev/mtd3
nanddump -f /tmp/Factory.bin /dev/mtd4
nanddump -f /tmp/FIP.bin /dev/mtd5
nanddump -f /tmp/ubi.bin /dev/mtd8
nanddump -f /tmp/KF.bin /dev/mtd12
```
Then, transfer them to your computer via scp, netcat, tftp
or others and keep them in a safe place.
3. Setup Nvram
Get the current stock: `cat /proc/cmdline`
If you find `firmware=0` or `mtd=ubi`, use these commands:
```
nvram set boot_wait=on
nvram set uart_en=1
nvram set flag_boot_rootfs=1
nvram set flag_last_success=1
nvram set flag_boot_success=1
nvram set flag_try_sys1_failed=0
nvram set flag_try_sys2_failed=0
nvram commit
```
If you find `firmware=1` or `mtd=ubi1`, use these commands:
```
nvram set boot_wait=on
nvram set uart_en=1
nvram set flag_boot_rootfs=0
nvram set flag_last_success=0
nvram set flag_boot_success=1
nvram set flag_try_sys1_failed=0
nvram set flag_try_sys2_failed=0
nvram commit
```
4. Flash stock-initramfs-factory.ubi
If you find `firmware=0` or `mtd=ubi`:
`ubiformat /dev/mtd9 -y -f /tmp/stock-initramfs-factory.ubi`
If you find `firmware=1` or `mtd=ubi1`:
`ubiformat /dev/mtd8 -y -f /tmp/stock-initramfs-factory.ubi`
Then reboot your router, it should boot to the openwrt
initramfs system now.
5. Setup uboot-env
Now it will be setup automatically in upgrade process,
you can skip this step.
If your `fw_setenv` did not work, you need run this command:
`echo "/dev/mtd1 0x0 0x10000 0x20000" > /etc/fw_env.config`
Then setup uboot-env:
```
fw_setenv boot_wait on
fw_setenv uart_en 1
fw_setenv flag_boot_rootfs 0
fw_setenv flag_last_success 1
fw_setenv flag_boot_success 1
fw_setenv flag_try_sys1_failed 8
fw_setenv flag_try_sys2_failed 8
fw_setenv mtdparts "nmbm0:1024k(bl2),256k(Nvram),256k(Bdata),
2048k(factory),2048k(fip),256k(crash),256k(crash_log),
34816k(ubi),34816k(ubi1),32768k(overlay),12288k(data),256k(KF)"
```
6. Flash stock-squashfs-sysupgrade.bin
Use shell command:
`sysupgrade -n /tmp/stock-squashfs-sysupgrade.bin`
Or go to luci web.
If you need to change to Openwrt U-Boot layout, do next. If you
do not need, please ignore it.
Change to OpenWrt U-Boot:
1. Flash ubootmod-initramfs-factory.ubi
Check mtd partitions: `cat /proc/mtd`
```
mtd7: 00040000 00020000 "KF"
mtd8: 02200000 00020000 "ubi_kernel"
mtd9: 04e00000 00020000 "ubi"
```
Run following command:
`ubiformat /dev/mtd8 -y -f /tmp/ubootmod-initramfs-factory.ubi`
Then reboot your router, it should boot to the openwrt initramfs
system now.
2. Check mtd again
```
mtd7: 00040000 00020000 "KF"
mtd8: 07000000 00020000 "ubi"
```
Make sure mtd8 is ubi.
3. Install kmod-mtd-rw
Run command: `opkg update && opkg install kmod-mtd-rw`
Or get it in openwrt server, or build it yourself, then install
it manually
Then run this command:
`insmod /lib/modules/$(uname -r)/mtd-rw.ko i_want_a_brick=1`
4. Clean up pstore
Run Command: `rm -f /sys/fs/pstore/*`
5. Format ubi and create new ubootenv volume
```
ubidetach -p /dev/mtd8; ubiformat /dev/mtd8 -y; ubiattach -p /dev/mtd8
ubimkvol /dev/ubi0 -n 0 -N ubootenv -s 128KiB
ubimkvol /dev/ubi0 -n 1 -N ubootenv2 -s 128KiB
```
6. (Optional) Add recovery boot feature.
```
ubimkvol /dev/ubi0 -n 2 -N recovery -s 10MiB
ubiupdatevol /dev/ubi0_2 /tmp/ubootmod-initramfs-recovery.itb
```
7. Flash Openwrt U-Boot
```
mtd write /tmp/ubootmod-preloader.bin BL2
mtd write /tmp/ubootmod-bl31-uboot.fip FIP
```
6. Flash ubootmod-squashfs-sysupgrade.itb
Use shell command:
`sysupgrade -n /tmp/ubootmod-squashfs-sysupgrade.itb`
Or go to luci web.
Now everything is done, Enjoy!
Go Back to stock from Openwrt U-Boot:
1. Force flash ubootmod-initramfs-recovery.itb
Use shell command:
`sysupgrade -F -n /tmp/ubootmod-initramfs-recovery.itb`
Or go to luci web.
Then it should boot to the openwrt initramfs system now.
2. Format ubi and Nvram
```
ubidetach -p /dev/mtd8; ubiformat /dev/mtd8 -y; ubiattach -p /dev/mtd8
mtd erase Nvram
```
3. Install kmod-mtd-rw
Run command: `opkg update && opkg install kmod-mtd-rw`
Or get it in openwrt server, or build it yourself, then install
it manually
Then run this command:
`insmod /lib/modules/$(uname -r)/mtd-rw.ko i_want_a_brick=1`
4. Flash stock U-Boot and ubi
```
mtd write /tmp/BL2.bin BL2
mtd write /tmp/FIP.bin FIP
mtd write /tmp/ubi.bin ubi
```
Then reboot your router, waiting it finished rollback in minutes.
Go Back to stock from stock layout Openwrt:
Just run command: `ubiformat /dev/mtd8 -y -f /tmp/ubi.bin`
Then reboot your router, waiting it finished rollback in minutes.
Notes:
1. Openwrt U-Boot and ubootmod openwrt did not enable NMBM.
Please make your backup safe.
