thnx. it seems latest working vendor kernel for 3566 is 6.1.115. i already tried rk35xx, with bigtreetech_cb2.dtb but it stops at u-boot (in uart console) using orangepi-3b it boots, but gives errors in dmesg. when i try to add fdtfile bigtreetech_cb2.dtb, it stops boot .... 47274496 bytes read in 3902 ms (11.6 MiB/s) Failed to load '/boot/dtb/rockchip/rk3566-bigtreetech-cb2.dtb' libfdt fdt_check_header(): FDT_ERR_BADMAGIC No FDT memory address configured. Please configure the FDT address via "fdt addr <address>" command. Aborting! Trying kaslrseed command... Info: Unknown command can be safely ignored since kaslrseed does not apply to all boards. Unknown command 'kaslrseed' - try 'help' ..... but when i boot btt_cb2 as orangepi3b board, it boots and even shows mpp venc/dec/npu/whatever modules properly loaded. not checked yet if it works really maybe need to make some hybrid dtb from btt_cb2 and orange3b ========= btw, could You share what You do for 35xx board change? when i tried to change family rockchip64 to 35xx, it comiled, but not copied bigtreeetech_cb2.dtb to boot , and not boots ewven if i copy it by myself there

features i looking for is a MPP/NPU - quite decent video encoders/processing/npu engine support, unfortunateli it still sticks to vendor 6.1.y kernel.

Hi all i tried to compile BTT CB2 with bookworm and vendor kernel to get MPP and NPU working, but got that : sha256sum: config/kernel/linux-rockchip64-vendor.config: No such file or directory is it missed ? How to compile vendor kernel for MPP support? thanks
