Is there a reason that you need specific that kernel version?

At least for the rk3588 the dtb version must match with the kernel version so I assume it's the same with yours. In this case it might be easier to create an image with the Armbian build system, just put the rt patch in the right folder, for example patch/kernel/archive/rockchip64-6.9 and start with ./compile and choose that you want to see the kernel config before you'll compile it.

Although they only support Linux 6.6, 6.9 and 6.12 (which don't need a rt patch). But if for some reason you need an older kernel you could just find an image with the same version kernel you've compiled and copy that dtb.

I saw that it's a rk3399 indeed, but here it also worked great for a s912 sbc so it might be a good base for yours too.

 

while a go you've provided a rt kernel for my orange pi 5 plus. can u do the same for this one (orange pi 4 lts) ? i mean a real-time 5.10.43 kernel for rk3399?

Thanks Scott, it's a spindle encoder I'm trying to get working. Its just the first step to get the PV1 counting in Halshow so I know at least the hardware is working. I'll look at my wiring again. Config setup for the encoders. No not using the MPG , just needed to rule out I didn't need that .so installed for the encoders to work. I have everything else working the lathe with this controller, axis ,spindle and tool changer

Thanks, I've tried to relink the files in boot directory to my new kernel files, still same problem.
In the source that I compiled from, I noticed that there is no dts and dtsi files and other related files for rk3399 in that source. can it be the problem for not booting after compilation?
if it can be, how can I solve this problem?
is there any other source besides kernel.org?

I tried another thing too, I used another sources like rockchip and orangepi-build. but whenever I wanna patch the real-time patch (got from kernel.org), it fails and says there are conflicts and incompatibility/

Exactly what I was looking for.

Thank you
