Can I specify a prebuilt version of toolchain only for kernel building?

Hello
I got a board (Rockchip RV1126), whose NPU driver kernel module is distributed in binary form, which requires specific kernel version (4.19.111) and toolchain version (gcc 10.3) ( I built the yocto with the specified kernel version, but using yocto shipped gcc 11, when I insmod, the driver reported invalid module format, and modprobe reported invalid exec format, I guess that is due to gcc version is incompatible ) I'm building the system with yocto kirkstone, which ships gcc 11. Can I have some way to just specify using external toolchain with prebuilt gcc 10.3 while other system still be built with default yocto shipped toolchain? I have seen meta-external-toolchain and meta-soucery, but it seems it will replace whole toolchain with this external version. Can I find a mean to just specify for building kernel ? Thanks |

before we start on that path, perhaps verify that you can run the kernel that you build with gcc 10.3 externally but manually building it and replacing it on target you can use a prebuilt toolchain from https://toolchains.bootlin.com/releases_aarch64.html

Like I said the driver (galcore.ko) is running on kernel 4.19 built with gcc10.3, yes I verified the kernel can run on my target hardware. I didn't need the toolchain, what I need is integrating a prebuilt toolchain only for kernel build. On Tue, Feb 21, 2023 at 1:26 AM Khem Raj <raj.khem@...> wrote:
