@iav Yes, thank you. I'll be able to test the PR for you next week.

@iav individual dts files attached , the other part of the dtb at the top of this thread is to run the eMMC in HS400 mode but that's already in the mainline. The source is this post rockchip-rk3399-l2-cache.dts rockchip-rk3399-op1-opp.dts

@iav @prahal are you the maintainers of the Helios64 bsp ? I'd be happy to test builds if you don't have physical hardware. My motivation is that it would be useful to be able to download the current image and run it without it hanging or throwing a kernel panic because the build is unstable without patches for the RK3399K on this board. Cheers, Jon

@ebin-dev good idea, I can try that. For the moment I seem to have a stable system running 25.11.2 with the 6.12.58 kernel and the l2-cache and op1-opp patches loaded as kernel overlays. My use case for the Helios64 is as a NAS with OMV8 and ZFS. Who is the maintainer of this board now ? I'm happy to test images on my hardware and it would be good if the latest builds worked out of the gate without having to patch them.

@BipBip1981 the dtb posted for the 6.18 kernel is different to the dtb posted for the 6.6 kernel though so where can I find the dtb built for the 6.12 kernel that Prahal shared with you rk3399-kobol-helios64.dtb-6.XX.xx-L2-hs400-opp ?

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 ?

@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 ?!

@BipBip1981 the challenge is being able to get it to boot to the shell so that I can update the dtb though (unless there is another way) !

Background - I have a Helios64 NAS with 4 x HDDs running Armbian 25.11.2 with kernel 6.12.58. The HDDs each have a ZFS partition but the partitions aren't imported. The OS is running from an sd card and logging is to ram. Power management and spin-down on the HDDs is disabled. Despite all this *something* is causing the heads to move every second or two. iotop shows no disk activity . lsof +d /mnt/sda etc. shows no open files and fatrace shows files in /usr and /var but nothing on /dev/sda etc. So, whilst it doesn't look as if any files are being accessed the HDDs are still doing something. The question is WHAT and how do I stop it ? Any ideas ?

@BipBip1981 where can I download rk3399-kobol-helios64.dtb-6.XX.xx-L2-hs400-opp ? Thanks

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 ?

I got bitten by this and in the end rolled back to Armbian 24.2.1 with kernel 6.6.16 which seems to work fine (with zfs and omv 7). Can anyone comment as to how much work would be required to fix this issue in the 25.x development and how much time would be required to bring this board up to be supported again ?
