这不是设备树语法问题,您只需使用c预处理器cpp预处理.dts文件,就可以获得设备树编译器可以按原样消化的文件。

在特定情况下,假设当前目录是内核根目录,则必须使用以下两个命令:

cpp -nostdinc -I include -I arch -undef -x assembler-with-cpp arch/arm64/boot/dts/amlogic/meson-gxl-s905x-khadas-vim.dts meson-gxl-s905x-khadas-vim.dts.preprocessed

dtc -I dts -O dtb -p 0x1000 meson-gxl-s905x-khadas-vim.dts.preprocessed -o kvim1.dtb
