Bricked Radxa Zero? " Invalid partition 1 "

tinic · September 28, 2021, 6:57am

So, I was flashing the 13GB large TwisterOS.Armbian.Focal.Radxa-Zero.Beta4.img when it failed in the middle of flashing using Etcher.

Now, when load “rz-udisk-loader.bin” I get the attached failure. I can’t seem to recover from this, erasing the eMMC again has no effect.

I guess my Radxa Zero is bricked?

You didn’t need to extract the 3.2GB img.xz TwisterOS Beta4 image, that’s only necessary when you transfer or manually copy extracted 13GB TwisterOS Beta4 image to uSD(MicroSD) or eMMC using dd commands. When using Etcher you use 3.2Gb downloaded TwisterOS Beta4 image for Zero.

How were you exactly flashing a extracted 13GB TwisterOS image to eMMC using Etcher, was it to eMMC right? Can you still boot from uSD(microSD) with a TwisterOS image? What’s the eMMC size?

If you still can boot from uSD, then go into CLI(Command Line) and delete eMMC contents/partition:

sudo dd if=/dev/zero of=/dev/mmcblk2 bs=1M count=100

sudo reboot

Yes, I was flashing the to the eMMC, I have a 4/16GB model.

If I insert an uSD right now with TwisterOS installed and without touching anything I end up in the USB boot loader and nothing further happens:

And yes, the SD card is the right side up , pins point towards the board.

I had the same problem. You have to use the linux fastboot commands to erase the emmc completely. With the windows tool, it looks like erasing is not working correctly (there is no error)

sudo fastboot flashing unlock_critical
sudo fastboot flashing unlock
sudo fastboot erase bootloader
sudo fastboot erase bootloader-boot0
sudo fastboot erase bootloader-boot1

Another thread finally mentioned what the correct command sequence is. I spent hours on this… Frustrating that the documentation is so bad.

Install prerequisites:

sudo apt install python3-pip curl
sudo pip3 install pyamlboot
bash <(curl -s https://raw.githubusercontent.com/corbindavenport/nexus-tools/master/install.sh)

That bash script above is somewhat broken on some distros and will not correctly add ~/.nexustools to PATH. You might have to do this by hand or use ~/.nexustools/fastboot directly.

Then get these images:

wget https://dl.radxa.com/zero/images/loader/rz-udisk-loader.bin
wget https://dl.radxa.com/zero/images/loader/rz-fastboot-loader.bin
wget https://dl.radxa.com/zero/images/loader/factory-loader.img

Replug the Zero with the USB button pressed. Then do this one time only:

sudo boot-g12.py factory-loader.img
sudo fastboot flashing unlock_critical
sudo fastboot flashing unlock

Replug the Zero with the USB button pressed. Then erase the entirety of the eMMC (can be done many times):

sudo boot-g12.py rz-fastboot-loader.bin
sudo fastboot erase bootloader
sudo fastboot erase 0
sudo fastboot erase 1

Replug the Zero with the USB button pressed. After that we can go into usb-disk mode to use Etcher:

sudo boot-g12.py rz-udisk-loader.bin

Of note: It’s really useful to use the UART port for debugging. I don’t see how I would have ever figured it out otherwise. Not very user friendly for sure. But that leads me to a much bigger concern: UART1 is not user accessible anymore. My plan was to investigate if the Radxa Zero could be used as a drop in replacement for a Raspberry Zero for use in a Prusa 3D printer. In the way the UART1 port is used right now that will not work since the Einsy RAMBo expects UART1 to be a normal serial device :-(((

Successfully installed the Debian image using the steps explained by @tinic with the following changes:

sudo fastboot erase 1 command failed
also ran sudo fastboot erase bootenv after sudo fastboot erase boot loader

Finally, after using Etcher to write the Debian image I ran the following to write the bootloader to eMMC:
sudo dd if=u-boot.bin of=/dev/sdx bs=512 seek=1

Also, this was powered via laptop port and when I plugged in HDMI the light did not turn on / black screen. Changed to use a USB port from the monitor and was able to boot successfully.
Once started I followed the instructions to connect WIFI and was able to login via SSH from laptop.

I followed different way, I faced with same situation while flashing Manjaro image via Etcher. I am windows 10 user.
1-I prepared ubuntu server uSD card and booted.
2-connected via ADB and activated WIFI connection.
3-Shifted form adb shell to ssh
4-updated repo and libraries on ubuntu server.
5-“sudo fdisk -l” listed disks and determined eMMC device
6-“sudo fdisk /dev/mmcblk0” after this command, created new partition by following help.
7-“sudo mkfs.ext4 /dev/mmcblk0” (
8-“systemctl poweroff”
With this aproach I do not need to change my computer OS.
