I am using the following script to transfer a system to another volume (in this case the running system to emmc) (UUIDs to be adapted to your case (sed -e 's/UUID=<from device>/UUID=<to device>/g' -i /mnt/emmc/etc/fstab)
 
#!/bin/bash # Check if user is root if [ $(id -u) != "0" ]; then echo "Error: You must be root to run this script." exit 1 fi cat > install-exclude <<EOF /dev/* /proc/* /sys/* /run/* # /tmp/* # /root/* EOF exec 2>/dev/null umount /mnt/emmc exec 2>&1 mount --uuid 7268e76f-3e1b-4e01-a6be-987654321098 /mnt/emmc rsync -avxSE --delete --exclude-from="install-exclude" / /mnt/emmc # change fstab sed -e 's/UUID=b790c4d7-5709-4000-91ac-123456789012/UUID=7268e76f-3e1b-4e01-a6be-987654321098/g' -i /mnt/emmc/etc/fstab sed -e 's/UUID=b790c4d7-5709-4000-91ac-123456789012/UUID=7268e76f-3e1b-4e01-a6be-987654321098/g' -i /mnt/emmc/boot/armbianEnv.txt umount /mnt/emmc rm install-exclude echo "All done."  
On top of that you may wish to manually rsync /var/log and /var/log.hdd to the other device.
The segmentation fault is probably caused by the wrong bootloader on emmc. Armbian tools might overwrite it. So install again the recommended bootloader to emmc.
Good luck.

Why don't you flash linux-u-boot-edge-helios64_22.02.1_arm64 to both devices mmcblk0 and mmcblk1 and perform the python3 check after a cold start ?

Armbian bullseye images can be downloaded from the archive. And if you are having issues with OMV7 you should open another thread.

The 6.6.8 debs were downloaded from an Armbian mirror and are not modified. Everything you need is explained here: in particular that NFS causes trouble with 6.6.x kernels and that 6.1.71 should be used instead or 5.15.93.
 
To implement hs400 and L2 cache information you can use 'dtc'. For your convenience I attached the dtb for 6.6.8 and 5.15.93 (just copy the matching one to /boot/dtb/rockchip/rk3399-kobol-helios64.dtb).
 
It is essential to flash the bootloader to emmc after you have installed the kernel debs, to perform a cold boot and to run 'sbc-bench -r' at least once.

@prahal Current helios64-u-boot-edge (2023-Dec-28 08:32) is supposed to include the rockchip DDR blob, but unfortunately stable operation of helios64 is still not possible with it: the r8152 is reset very frequently if this bootloader is used (contrary to linux-u-boot-edge-helios64_22.02.1_arm64.deb, were the r8152 is reset only occasionally under load).

@mrjpaxton Dist-upgrade(ing) from bullseye to bookworm did finally complete successfully. However, one should consider that device names have changed (otherwise your system may end up offline 🙂) the new interface names are:
 
# interface names (bookworm) sd: /dev/mmcblk0 emmc: /dev/mmcblk1 eth0: end0 (1GBase-T ethernet) eth1: end1 (2.5GBase-T ethernet)  
P.S.: I am currently setting up bookworm from scratch starting from the fresh image to get rid of the stuff that accumulated during the last years.

I can understand that you are disappointed.
 
But I think that Kobol had to pull the plug, in the context of the current chip shortage - with limited (sometimes even no) availability of components and SOCs and rising prices. That is not the right environment for a small start-up to grow. - it is a rather toxic environemnt that will lead to insolvency, as profitable growth is impossible to achieve. Without growth (no new/further products to offer) you are just faced with fixed costs and without income. Not sustainable at all.
 
All three of the founding members of Kobol deserve our full respect. They only drew a logical conclusion. Hopefully it can be reversed some time.

Some Helios64 had issues with CPU freezes or other instabilities. If you buy one you should make sure that you can give it back if it is one of those.

Hi,
 
updating Helios64 (Armbian Bullseye) to the latest kernel (Armbian 22.02.1 with Linux 5.15.25-rockchip64) went flawlessly - it seems to be stable so far (Thanks!).
However, emmc read/write speed is still reduced by a factor of 2 compared to linux 5.10.43.
 
@piter75 Do you know if there is anybody trying to re-enable high emmc read/write speeds in newer kernels  ?

I can understand that you are disappointed.

On emmc (/dev/mmcblk2p1) you just need to replace the root UUID in /etc/fstab and in /boot/armbianEnv.txt to match the UUID of your emmc (e4e3bcd6-3f03-4362-bbe0-f1654138c5d8). Then reboot without microsd in the slot...

A fresh Bullseye image is stable on Helios64 - just like the upgraded Buster image.

YEAH !
I can compile and boot linux-5.10.63, I only had to disable the rk3328 patches because some patches were rejected.
 
I booted from sdcard, updated the /boot folder, then rebooted from eMMC and I can again run and write on the eMMC :-)
 
 
EDIT: and upgraded to 5.10.64 this weekend without any issue
 

@piter75 commited the emmc fix into Armbian and built Armbian 21.08.2 which is already available through the Armbian mirrors (via 'apt update && apt upgrade').
 
It is save to upgrade your Buster or Bullseye installation to Armbian 21.08.2 - but emmc read speed will be about 50% what it used to be.
 
You can roll back to the previous linux 5.10.43 kernel if you don't like that - just install those files with 'dpkg -i *.deb'.

Really ?
If you are on macOS Big Sur all the drivers and apps are already there. If you need to access the serial console of your Helios64, just connect your mac to the USB-C port of your Helios64. A device such as  /dev/tty.usbserial-XXXXXXXX will be recognised by macOS. All you need to do then is to enter the following into the Terminal of your mac (X to be replaced):
 
screen /dev/tty.usbserial-XXXXXXXX 1500000 -L  
Edit: If the 'screen' command on macOS does not show the output of the bootloader (scrambled characters) you could use the app serial. The only thing you need to configure is to set the serial speed manually to 1500000 bps.
 
If someone would like to contribute in kernel testing - the Armbian build system is very easy to install and use. All you need is an Ubuntu 21.04 (amd64) installation. All the rest is explained here. To compile your own kernel is then as simple as this:
./compile.sh BOARD=helios64 BRANCH=current KERNEL_ONLY=yes RELEASE=bullseye

The easiest way to downgrade linux on emmc now would be to copy those files to /mnt/system (root directory of your emmc) - and then change root with  'chroot /mnt/system' and install the packages with 'dpkg -i *.deb'   (while your active system is on SD).
 
You can leave the chrooted environment by typing 'exit'. emmc should now be bootable again. If not, you need to update the bootloader on emmc as described earlier in this thread.
