Helios64 - Armbian Trixie with linux 6.18 (incl. opp-microvolt patch)

[ebin-dev]

The most current download images for Helios64 are now all provided with linux 6.18.xx.

 

I downloaded a minimal image and checked the dtb: it would not appear to contain the opp-microvolt patch that made Helios64 finally stable.

 

So for the ones who have stability issues again on Helios64, I attached the patched dtb compiled for linux 6.18.xx using the exact same opp-microvolt values as in the previous dtb versions I compiled for linux 6.6 and 6.12. The current linux deb files can be downloaded from beta.armbian.com, the linux 6.18.18 deb files I used can be downloaded from here (to be installed with 'dpkg -i linux*').

 

In order to install the dtb, simply unzip it, copy it into the proper location, update initramfs and reboot:

 

# install the dtb with the opp-microvolt patch:
unzip rk3399-kobol-helios64.dtb-6.18.18-opp.zip
cp rk3399-kobol-helios64.dtb-6.18.18-opp /boot/dtb/rockchip/rk3399-kobol-helios64.dtb
update-initramfs -u
reboot

Thank a lot !

Thanks for doing this @ebin-dev. Any tips on how to load the alternate dtb if the hardware is so unstable that it won't even boot to the shell; I'm using 26.2.1 / 6.18.15 ?

Boot on a from scratch helios64 sdcard image, cross fingers and copy / rename / replace original dtb file with ebin-dev file or mount sdcard with scratch helios64 on another computer, do the change, then boot with you ready sdcard on the helios64

@BipBip1981 that is the challenge though - getting it to boot to the shell ! Copying the dtb onto the sd card isn't enough , you need to then rebuild the fs image and how do you do this if you can't boot from the image ?!

[SymbiosisSystems]

Ultimately if the only way to get the Helios64 to boot is to integrate the dtb changes do I need to be building my own image with the changes integrated (rather than copying them into a pre-built image) . @ebin-dev what would be required to get these dtb patches into the mainline build ?

[ebin-dev]

@SymbiosisSystems To get those changes into the mainline build is currently not the solution preferred by the maintainer of this board, because it is some kind of a hot fix.

 

To boot your helios64 to the command line you could try an image from the archive and boot from sd. A system on emmc could then be manipulated using chroot.
