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'm using those kernels just because the official links of orangepi provided them, If any rt-kernel can be installed, that would be great.
when I was using orange pi 5 plus, I used armbian 5.10.160. but I experienced a tough time with its SPI driver. after spending some time on that I thought it may be the armbian which its spi is not real-time and reliable.
That's why this time I was avoiding to installing armbian.
if you think armbian is reliable in SPI, then this time i will try this way.

Here are some more detailed photos.I've also just shared the 3D files of some elements on Thingiverse .

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

Check with "ls -l /boot" if all links are correct. With Armbian for example the Image file is a link to the used kernel. To relink you can use "sudo ln -sf your-rt-kernel Image" and also check for the uinitrd link and to use the right dtb for that kernel version.

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/
