I know this isn't the CORRECT fix. But, I managed to hack a working image by modifying the file kernel-deb.sh At line 52, I changed declare kernel_version_family="${kernel_version}-${BRANCH}-${LINUXFAMILY}" to declare kernel_version_family="${kernel_version}-rt47-${BRANCH}-${LINUXFAMILY}" The board booted, and uname shows the kernel I expected $ uname -a Linux orangepizero2w 6.6.65-rt47-current-sunxi64 #7 SMP PREEMPT_RT Wed Dec 11 15:13:43 UTC 2024 aarch 64 GNU/Linux

In short, I'm trying to build a FULLY-PREEMPT-REALTIME system to run on my Orange Pi Zero 2W. I used this post as a reference, and got quite far. But, I'm stuck on something that I believe I undestand, but don't know how to resolve. I don't believe this is a probleme specific to my board though. What I've done so far with success is both install and run a pre-built Armbian Image on this board, as well as build my own image and run it. Both work perfectly. Now, I'm attempting to apply the RT patch and build a fresh image (or even just a Kernel) to get the FULL REALTIME kernel support working. However, the build system fails after the kernel is built sucesfully, as it is unable to find the resulting kernel image generated. I belive the issue is simply that when the RT .patch is applied and configured to the kernel, it builds a kernel file with an alterered filename. Instead of 6.6.65-current-sunxi64 It creates 6.6.65-rt47-current-sunxi64 As a result, the build process for the kernel stage fails as it's unable to find the file it is expecting to find. Here is what I have done, and what outputs I am finding. As stated, It was a success with A locally built clean Armbian ./compile.sh BOARD=orangepizero2w BRANCH=current RELEASE=bookworm BUILD_MINIMAL=yes BUILD_DESKTOP=no KERNEL_CONFIGURE=no AUFS=no KERNELBRANCH='tag:v6.6.65' System booted up and ran as normal. $ uname -a inux orangepizero2w 6.6.65-current-sunxi64 #2 SMP Wed Dec 11 15:13:43 UTC 2024 aarch64 GNU/Linux I then attempted to apply the PREEMPT_RT kernel patch. download and gunzip https://cdn.kernel.org/pub/linux/kernel/projects/rt/6.6/patch-6.6.65-rt47.patch.gz into the directory userpatches/kernel/archive/sunxi-6.6 Then a kernel-configure step Worth noting that I do see this patch file applied in the output of the following command. ./compile.sh BOARD=orangepizero2w BRANCH=current RELEASE=bookworm KERNELBRANCH='tag:v6.6.65' kernel-config Where I proceeded to enable the full REALTIME kernel (4th option). General setup -> Preemption Mode -> Fully Preemptible Kernel (Real-Time) Finally followed with a compile command. ./compile.sh BOARD=orangepizero2w BRANCH=current RELEASE=bookworm BUILD_MINIMAL=yes BUILD_DESKTOP=no KERNEL_CONFIGURE=no AUFS=no KERNELBRANCH='tag:v6.6.65' The part of the build output that I beleive is relevant is this. It shows the failure, and what I believe is an indication of why it fails. It appears that the build script it is not aware of needing to find the file name that has the rt47 portion. 🐳|🔨] INSTALL /armbian/.tmp/work-3b1e65cb-74c9-47f6-aa6c-d7787497b9b0/kernel_dest_install_dir-44x4J/dtbs/allwinner/overlay/sun50i-h616-i2c1-pi.dtbo [🐳|🔨] INSTALL /armbian/.tmp/work-3b1e65cb-74c9-47f6-aa6c-d7787497b9b0/kernel_dest_install_dir-44x4J/dtbs/allwinner/overlay/sun50i-h616-i2c2-pi.dtbo [🐳|🔨] INSTALL /armbian/.tmp/work-3b1e65cb-74c9-47f6-aa6c-d7787497b9b0/kernel_dest_install_dir-44x4J/dtbs/allwinner/overlay/sun50i-h616-gpu.dtbo [🐳|🔨] INSTALL /armbian/.tmp/work-3b1e65cb-74c9-47f6-aa6c-d7787497b9b0/kernel_dest_install_dir-44x4J/dtbs/allwinner/overlay/sun50i-a64-fixup.scr [🐳|🔨] INSTALL /armbian/.tmp/work-3b1e65cb-74c9-47f6-aa6c-d7787497b9b0/kernel_dest_install_dir-44x4J/dtbs/allwinner/overlay/sun50i-h5-fixup.scr [🐳|🔨] INSTALL /armbian/.tmp/work-3b1e65cb-74c9-47f6-aa6c-d7787497b9b0/kernel_dest_install_dir-44x4J/dtbs/allwinner/overlay/sun50i-h6-fixup.scr [🐳|🔨] INSTALL /armbian/.tmp/work-3b1e65cb-74c9-47f6-aa6c-d7787497b9b0/kernel_dest_install_dir-44x4J/dtbs/allwinner/overlay/sun50i-h616-fixup.scr [🐳|🔨] INSTALL /armbian/.tmp/work-3b1e65cb-74c9-47f6-aa6c-d7787497b9b0/kernel_dest_install_dir-44x4J/dtbs/allwinner/overlay/README.sun50i-a64-overlays [🐳|🔨] INSTALL /armbian/.tmp/work-3b1e65cb-74c9-47f6-aa6c-d7787497b9b0/kernel_dest_install_dir-44x4J/dtbs/allwinner/overlay/README.sun50i-h5-overlays [🐳|🔨] make[1]: Nothing to be done for 'install'.
