U-Boot flash instructions:
0. OpenWrt U-Boot does not support stock layout, it comes with recovery
boot support, automatic tftp recovery and never blocks UART.
A new flash layout is introduced, we call it OpenWrt U-Boot layout,
stock flash layout and the old OpenWrt layout are not supported.
During the whole flash procedure, please do not reboot or power off
unless requested explicitly, or you will break your device.
1. Your device should already running OpenWrt.
If not, follow the instructions to flash OpenWrt:
https://github.com/openwrt/openwrt/pull/11115
2. Backup BL2 Nvram Bdata Factory and FIP in case you break something or
in case you want to go back to stock firmware one day.
cat /dev/mtdblock0 > /tmp/BL2.bin
cat /dev/mtdblock1 > /tmp/Nvram.bin
cat /dev/mtdblock2 > /tmp/Bdata.bin
cat /dev/mtdblock3 > /tmp/Factory.bin
cat /dev/mtdblock4 > /tmp/FIP.bin
And save all whose bin files to somewhere safe.
Then backup your configurations, since ubiformat for entire mtd device is
required to create new ubootenv volume for OpenWrt U-Boot.
3. Run the following cmd to boot into an initramfs with the new OpenWrt
U-Boot layout that expand ubi partion to the end of flash:
ubiformat /dev/mtd7 -y -f /tmp/ax6000-ubootmod-initramfs-factory.ubi
4. After boot into initramfs, check mtd partion info.
The ubi partion should be mtd5
root@OpenWrt:~# cat /proc/mtd
dev: size erasesize name
mtd0: 00100000 00020000 BL2
mtd1: 00040000 00020000 Nvram
mtd2: 00040000 00020000 Bdata
mtd3: 00200000 00020000 Factory
mtd4: 00200000 00020000 FIP
mtd5: 07a80000 00020000 ubi
5. Load kmod-mtd-rw to temporarily make the bootloader partions writable.
The kmod-mtd-rw is from the feeds, it is not packed in initramfs-factory
by default.
To install kmod-mtd-rw via opkg:
opkg update && opkg install kmod-mtd-rw
Or, download kmod-mtd-rw.ipk from OpenWrt server and install it manually
e.g:
https://downloads.openwrt.org/snapshots/targets/mediatek/filogic/kmods/
Select your OpenWrt release version and kernel version accordingly.
Load kmod-mtd-rw:
insmod /lib/modules/$(uname -r)/mtd-rw.ko i_want_a_brick=1
6. Run the following cmd to clean all pending crash dumps in pstore,
or OpenWrt U-Boot may boot into NAND recovery or tftp recovery.
rm -f /sys/fs/pstore/*
7. Format ubi and create new ubootenv volume:
ubidetach -p /dev/mtd5; ubiformat /dev/mtd5 -y; ubiattach -p /dev/mtd5
ubimkvol /dev/ubi0 -n 0 -N ubootenv -s 128KiB
ubimkvol /dev/ubi0 -n 1 -N ubootenv2 -s 128KiB
8. This is optional. Skip this if you do not want to have NAND recovery
boot feature offered by OpenWrt U-Boot. Don't worry, you always have
automatic tftp recovery feature enabled.
ubimkvol /dev/ubi0 -n 2 -N recovery -s 10MiB
ubiupdatevol /dev/ubi0_2 /tmp/ax6000-ubootmod-initramfs-recovery.itb
9. Now, flash new U-Boot. Bye-bye ugly stock U-Boot.
mtd write /tmp/ax6000-ubootmod-preloader.bin BL2
mtd write /tmp/ax6000-ubootmod-bl31-uboot.fip FIP
10. Flash the squashfs-sysupgrade.bin as usual:
sysupgrade -n /tmp/ax6000-ubootmod-squashfs-sysupgrade.itb
Enjoy!

The Bananapi BPi-R3 board can boot from eMMC, SD card, SPI-NAND and
SPI-NOR, depending on the position of switches controlling the BOOTSEL
bootstrap pins as we as hard-wired chip-select lines. The position of the
chip-select switch SW6 decides whether either SD card or eMMC can be
accessed, SW5 selects either SPI-NAND or SPI-NOR.
Generate U-Boot for all 4 boot options. The SD card version allows
installation to SPI-NAND and SPI-NOR (eMMC cannot be accessed
simultanously with the SD card), the SPI-NAND version allows installation
to eMMC.

Building U-Boot for the MT7621 SoC requires binman, a Python-based
host tool to generate images. For now, binman cannot work inside the
OpenWrt build system because it requires swig, so mark the MT7621
boards as borken to fix the ramips/mt7621 build until someone with
knowledge about Python and swig fixes the underlaying issue.

* Merge uboot-ramips into uboot-mediatek.
* Port support for the RAVPower RP WD009 to U-Boot 2022.07.
* Add support for MT7621 and add builds for the reference boards.
* Add builds for MT7620 and MT7628 reference boards.
This should help to make development of U-Boot-level board support for

Add U-Boot build for the Ubiquiti Networks UniFi 6 LR access point.
This allows updating the bootchain to modern ARM Trusted Firmware 2.4
and U-Boot 2021.04 while keeping as much of the existing flash layout
as possible (u-boot-env, factory and eeprom partitions are retained),
gaining robust recovery vs. production dual-boot mechanism.
Add info for the Winbond W25Q512JV SPI NOR flash used in the device
and wait for GPIOs to settle after reset before checking for reset
button.
I2C connected LED controller is not supported yet.
Writing large amounts of data to SPI flash currently doesn't work due
to watchdog timeout causing reset before data write completes.

Build U-Boot for the Linksys E8450 in order to have support for UBI.
The loader has a default environment with scripts handling the reset
button as well as fall-back to recovery firmware. If the loader comes
up without a valid environment found in UBI, it will automatically
make sure UBI is formatted and create a new environment and proceed
to load recovery firmware (either from UBI or via TFTP if recovery is
corrupted or unavailable).
If the button is held down during power-on, the yellow status LED
turns on and the bootloader environment is reset to factory defaults.
If the button is released at this point, the recovery firmware (if
existing) is loaded from UBI and booted.
If the button is continously held down even beyond the point that
the yellow LED turned on, the loader will try to load the recovery
firmware via TFTP from server 192.168.1.254, write it to UBI and
boot.
