Known Issues
------------
U-Boot vendor recovery does not seem to accept any images, neither
GL.iNet images nor OpenWrt images. Recovery requires serial access!
Installation
------------
Upload the OpenWrt sysupgrade image to the Gl.iNet Web-UI. Make sure to
not retain existing settings.

To create a correct BL2, I had to add a profile for 'spim:4k+256' as I could not find a way to value the variable 'NAND_TYPE'.
Features and fixes from hitech95 tree has been squashed, I'm attaching his commit message:
The Power LED was not working correctly and not reacting
to the boot process and statuses.
The board has space (footprint) for an unpopulated Zigbee chip,
while we dont know the device model having this chip populated
we have to assure that the common dts doesnt enable
interfaces that share pins with such device.
In this instance the PCIe and the uart1 and uart2 are disabled.
Some of the control PCIE pins seems to be used for the Zigbee chip,
UART1 seems to be used as a flash port while UART2 should be the
main comunication interface of Zigbee chip.
The Zigbee chip should be a EFR32MG21. But the pins used for UART
seems to be not on standard PINS used by other adapters.
So it cannot run firmwares shared on the web.
But it should be possible to build a custom firmware with
the corrtect pinmux.
This commit also contains the following squashed commit from hitech95
- mediatek: fix sysupgrade for Zyxel EX7601-T0 ubootmod
Changes and fixes added in common board:
- added aliases for boot status leds.
- added aliases for the mac-label-device.
- added pin claims for core features (MDIO and UART 0)
- added default LEDs configuration (01_leds)
- added default network configuration (02_network)
- added missing kmod-usb3 module for USB3
- fixed LED names
- fixed reset pin for SLIC chip
- removed unused pinmux configurations and devices
- fix LAN (switch) port numbering
- using nvmem cells for wifi eeprom, dropping deprecated "mediatek,mtd-eeprom"
- proper factory partition and mac address handling
- cleaned up spi_nand sections and partition
Changes and fixxes added in stock layout:
- added NMBM, if u-boot has it, the kernel must be informed.

Telenor quirks
--------------
The operator specific firmware running on the Telenor branded
ZyXEL EX5700 includes U-Boot modifications affecting the OpenWrt
installation.
Notable changes to U-Boot include
- environment is stored in RAM and reset to defaults when power
cycled
- dual partition scheme with "nomimal" or "rescue" systems, falling
back to "rescue" unless the OS signals success in 3 attempts
- several runtime additions to the device-tree
Some of these modifications have side effects requiring workarounds
- U-Boot modifies /chosen/bootargs in an unsafe manner, and will crash
unless this node exists
- U-Boot verifies that the selected rootfs UBI volume exists, and
refuses to boot if it doesn't. The chosen "rootfs" volume must contain
a squashfs signature even for tftp or initramfs booting.
- U-Boot parses the "factoryparams" UBI volume, setting the "ethaddr"
variable to the label mac. But "factoryparams" does not always
exist. Instead there is a "RIP" volume containing all the factory
data. Copying the "RIP" volume to "factoryparams" will fix this

2. Attach UART, pause at u-boot menu.
3. Select "Upgrade ATF BL2", then use preloader.bin
4. Select "Upgrade ATF FIP", then use bl31-uboot.fip
5. Download the initramfs image, and type "reset",
waiting for tftp recovery to complete.
6. After openwrt boots up, perform sysupgrade.
Note:
1. Since NMBM is disabled, we must back up all partitions.
2. Although we can upgrade new firmware in the stock firmware,
we need the special fit image signature of MediaTek and

- write *mt7981-rfb-spim-nand-bl31-uboot.fip to 'FIP' partition
- erase 'ubi' partition
- reset board
- create ubootenv and ubootenv2 UBI volumes in U-Boot
- edit environment and set bootcmd, e.g.
setenv bootconf 'config-1#mt7981-rfb-spim-nand#mt7981-rfb-mxl-2p5g-phy-eth1'
setenv bootcmd 'ubi read $loadaddr fit; bootm $loadaddr#$bootconf'
- load initramfs image via TFTP:

setenv bootfile openwrt-mediatek-filogic-mediatek_mt7981-rfb-initramfs.itb
saveenv ; saveenv
tftpboot
bootm $loadaddr#$bootconf
- Now use sysupgrade to write OpenWrt firmware to flash.

Enable building a factory image which can be flashed through the OEM
firmware's web interface. It seems that the web interface requires a
minimum file size of 10MiB, otherwise it will not accept the image.
The update image is a regular sysupgrade tarball packed in a Netgear
encrypted image. The Netgear encrypted image is the same as used in
WAX202 or WAX206, including the encryption keys and IV.
This adds a script which creates the rootfs_data volume on first
startup. This is required since the OEM firmware's sysupgrade scripts
do not create such a paritition. Note that any script ordered after
70_initramfs_test will not get executed on initramfs. Hence this new
script 75_rootfs_prepare won't create the rootfs_data volume when
using the recovery initramfs.
Also, this deletes the kernel_backup and rootfs_backup volumes in case
we have to create the rootfs_data volumes. This makes sure that
OpenWrt is the actual backup firmware instead of the stock firmware.

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.

Installation
------------
1. Connect to the device using serial console.
2. Interrupt the Autoboot process when promted by sending '0' twice.
3. Serve the OpenWrt initramfs image using TFTP at 192.168.1.66. Name
the image "predator.bin" and conenct the TFTP server to the routers
LAN port.
4. Configure U-Boot to allow loading unsigned images from MMC
$ setenv bootcmd 'mmc read 0x40000000 0x00004400 0x0010000;
fdt addr $(fdtcontroladdr); fdt rm /signature; bootm 0x40000000';
saveenv
5. Transfer the image from U-Boot
$ setenv serverip 192.168.1.66; setenv ipaddr 192.168.1.1;
tftpboot 0x46000000 predator.bin; fdt addr $(fdtcontroladdr);
fdt rm /signature; bootm
6. Wait for OpenWrt to boot
7. Transfer the OpenWrt sysupgrade image to the router using scp.
8. Install OpenWrt using sysupgrade.
