The code I am trying to run modifies the framebuffer /dev/fb0, I seen that the code works properly on Linux 5.15 on a Raspberry Pi, but not on 6.x. I tried on Armbian with Linux 6.x but I got also a bad behavior that is why I wanted to test the old kernel. About real-time, it is because I need that the process executions are not interrupted by the kernel. Probably, it may be better for me to understand why the code doesn't work on 6.x.

Hello, I am new using the "build" tool. I am trying to compile Armbian using this config: # Board and kernel selection BOARD="rock-4se" # e.g., "odroidc4", "orangepi5", etc. BRANCH="current" RELEASE="jammy" # or "bookworm" for Debian # Build options BUILD_MINIMAL="yes" BUILD_DESKTOP="no" KERNEL_CONFIGURE="no" KERNEL_BTF=no # Use custom kernel KERNELSOURCE="https://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git" KERNELBRANCH="tag:v5.15.92-rt57" # Enable RT patch KERNEL_USE_GCC="yes" KERNEL_COMPILER="aarch64-linux-gnu-" # or aarch64-linux-gnu- for ARM64 # Disable non-needed drivers SKIP_EXTERNAL="yes" SKIP_BOOTSPLASH="yes" BUILD_KSRC="no" ENABLE_WIRELESS="no" BLUETOOTH_SUPPORT="no" WIREGUARD="no" DRIVER_UWE5622="no" DRIVER_RTL8723DU="no" DRIVER_RTL8723DS="no" I stored it in userpatches/config-rock-4se.h and I compile using ./compile.sh rock-4se. I get this error with wireless patches, it seems that they are not compatible with this kernel (?)
