DISCLAIMER NOTICE
- I'm not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed (like it did for me...).
- YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, I will laugh at you.

Open TTY with screen:
screen -L /dev/ttyUSB0 115200
Hint: press
ctrl + athen type:quitto quit.
Start your device and press any key until Hit any key to stop autoboot is displayed. You should see u-boot prompt:
Marvell>>
First, keep current u-boot parameters:
printenv
Keep the content of
printenvoutput. This will be a useful reference if you want to restore any u-boot parameters.
# You may need to build latest kwboot
sudo apt-get install u-boot-tools
kwboot -p -t -B 115200 /dev/ttyUSB0 -b ix4-200d-u-boot-2022.04.kwb
Hint: press
ctrl + \then typecto quit.
If you got the following error, you need to use the latest version of kwboot, build it from u-boot sources:
Sending boot message. Please reboot the target...- Sending boot image... 0 % [+xmodem: Protocol error
On USB key with debian, edit /uEnv.txt:
x_bootargs=console=ttyS0,115200 mtdparts=orion_nand:896k(uboot),128k(env),-(rootfs) initramfs.runsize=32M usb-storage.delay_use=0 rootdelay=1 usbcore.autosuspend=-1 fsck.repair=preen
x_bootargs_root=root=/dev/disk/by-path/platform-f1050000.ehci-usb-0:1.2:1.0-scsi-0:0:0:0-part1 rw rootfstype=ext2
x_bootcmd_kernel=ext4load usb 0:1 ${loadaddr} /boot/uImage
From u-boot prompt:
boot
# Load from USB uEnv.txt file
usb start; ext4load usb 0:1 ${loadaddr} uEnv.txt; env import -t ${loadaddr} ${filesize}
# OR set mannually environments
setenv x_bootargs console=ttyS0,115200 mtdparts=orion_nand:896k(uboot),128k(env),-(rootfs) initramfs.runsize=32M usb-storage.delay_use=0 rootdelay=1 usbcore.autosuspend=-1 fsck.repair=preen
setenv x_bootargs_root root=/dev/disk/by-path/platform-f1050000.ehci-usb-0:1.2:1.0-scsi-0:0:0:0-part1 rw rootfstype=ext4
# Load uImage from USB
ext4load usb 0:1 ${loadaddr} /boot/uImage
# Then set kernel args and boot
setenv bootargs ${x_bootargs} ${x_bootargs_root}; bootm ${loadaddr}
If everything is OK, load u-boot.kwb from USB key:
usb start
ext4load usb 0:1 0x1000000 /u-boot.kwb
or from TFTP server (plug on Ethernet port 2):
# setenv gatewayip 192.168.1.254
setenv ipaddr 192.168.1.250
tftpboot 0x1000000 192.168.1.48:u-boot.kwb
Then write it to nand:
nand erase 0x000000 0xe0000
nand write 0x1000000 0x000000 0xe0000
Set environments variables:
env default -a
# print default parameters:
printenv
setenv ethaddr 00:26:2d:06:ab:ac
setenv eth1addr 00:26:2d:06:ab:ad
env save
Reboot:
reset
Keep the content of
printenvoutput. This will be a useful reference if you want to restore any u-boot parameters.
