This variant uses xiaomi factory u-boot and modified u-boot-env &
bootcmd.
By modifying uboot-env, the xiaomi firmware recovery provided in
the vendor u-boot doesn't work anymore. It's possible to put
u-boot into a state where it refuese to take any serial input.
If the u-boot is in this state, users can't restore their
firmware without taking the flash off the board.
We now have a -stock variant where the vendor u-boot is used in
a way that xiaomi firmware recovery still works, and a -ubootmod
variant where we get rid of all xiaomi components, have more
usable space and no uart console lock. These two should cover all
use cases and we don't need this variant anymore.
Drop this redmi-ax6000 variant. Existing users of this variant
should perform a u-boot mod or restore to the -stock layout.

This new layout is only bootable with OpenWrt U-Boot. It reuses the
two crash partions and expands the ubi partion to the end of whole flash.
Do not use this layout with stock U-Boot!

In this implementation, the flash partition layout is adjusted to avoid
modifying the uboot environment of mtdparts. This ensures that the 30M
ubi_kernel partition remains aligned with the stock ubi partition, and
the kernel volume is placed in it. This allows the stock uboot to boot
from it without changing the mtdparts, which is useful for reverting back
to the stock firmware using Xiaomi Firmware Tools. In actual testing,
modifying mtdparts has been found to break Xiaomi Firmware Tools.
1. use ARTIFACTS to generate initramfs-factory.ubi for easy installation.
2. The NAND flash layout is changed to allow for reverting back to the
stock firmware.
3. Before performing sysupgrade, do some cleanup in platform_pre_upgrade
to ensure a clean installation of OpenWRT.
4. Setup the uboot env to ensure that the system always boot, which can
be helpful for users who may forget to do this before sysupgrade in
the initramfs.
New flash instructions:
1. Gain ssh access. Please refer to:
https://openwrt.org/toh/xiaomi/redmi_ax6000#installation)
2. Check which system current u-boot is loading from:
COMMAND: `cat /proc/cmdline`
sample OUTPUT: `console=ttyS0,115200n1 loglevel=8 firmware=1 uart_en=1`
if firmware=1, current system is ubi1
if firmware=0, current system is ubi0
3. Setup nvram and write the firmware:
If the current system is ubi1, please set it up so that the next time
it will boot from ubi, and write the firmware to ubi:
```
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
ubiformat /dev/mtd8 -y -f /tmp/initramfs-factory.ubi
```
If the current system is ubi, please set it up so that the next time
it will boot from ubi1, and write the firmware to ubi1:
```
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
ubiformat /dev/mtd9 -y -f /tmp/initramfs-factory.ubi
```
4. After rebooting, the system should now boot into the openwrt initramfs.
Flash the squashfs-sysupgrade.bin via using ssh or luci.
```
sysupgrade -n /tmp/squashfs-sysupgrade.bin
```
Done.
For existing users of the Redmi AX6000 running OpenWrt, here are the steps to
switch to this new layout:
1. Flash initramfs-factory.ubi
```
mtd -r -e ubi write /tmp/initramfs-factory.ubi ubi
```
2. After rebooting, the system will boot into the new openwrt-initramfs.
Log in and perform a sysupgrade to complete the process.
```
sysupgrade -n /tmp/squashfs-sysupgrade.bin
```

Flash instructions:
1. Gain ssh and serial port access, see the link below:
https://openwrt.org/toh/xiaomi/redmi_ax6000#installation
2. Use ssh or serial port to log in to the router, and
execute the following command:
nvram set boot_wait=on
nvram set flag_boot_rootfs=0
nvram set flag_boot_success=1
nvram set flag_last_success=1
nvram set flag_try_sys1_failed=8

3. Set a static ip on the ethernet interface of your computer
(e.g. default: ip 192.168.31.100, gateway 192.168.31.1)
4. Download the initramfs image, rename it to initramfs.bin,
and host it with the tftp server.
5. Interrupt U-Boot and run these commands:
setenv mtdparts nmbm0:1024k(bl2),256k(Nvram),256k(Bdata),2048k(factory),2048k(fip),256k(crash),256k(crash_log),112640k(ubi)
saveenv
tftpboot initramfs.bin
bootm
6. After openwrt boots up, use scp or luci web
to upload sysupgrade.bin to upgrade.
Revert to stock firmware:
Restore mtdparts back to default, then use the
vendor's recovery tool (Windows only).

The Bananapi BPi-R3 is a development router board built around the
MediaTek Filogic 830 (MT7986A) SoC.
The board can boot either from microSD, SPI-NAND, SPI-NOR or eMMC.
