reference https://github.com/LuckfoxTECH/luckfox_ ... gl_example The lvgl version is 8.+, but the latest version is already 9+, so after using 9.+, some other projects are referenced (using the CMake20 syntax). Therefore, using Rockchip830-linux-uclibnueabihff reports a syntax error and needs to be updated to the latest version that supports CMake 20. Is there a new Rockchip830-linux-uclibnueabihff SDK available to support the latest CMake.

The cross-compilation toolchain is provided by Rockchip, and many closed-source libraries are also built based on this toolchain. Replacing it may cause some of these closed-source libraries to become unusable. If necessary, you can try using crosstool-ng to build your own toolchain. Rockchip provides the original crosstool-ng defconfig file, which can be found at:
