這不是設備樹語法問題,您只需使用c預處理器cpp預處理.dts文件,就可以獲得設備樹編譯器可以按原樣消化的文件。

在特定情況下,假設當前目錄是內核根目錄,則必須使用以下兩個命令:

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

kvim1.dtb: Warning (unit_address_vs_reg): Node /scpi/clocks/scpi_clocks@0 has a unit name, but no reg property

kvim1.dtb: Warning (unit_address_vs_reg): Node /soc/bus@c8100000/pinctrl@14 has a unit name, but no reg property

kvim1.dtb: Warning (unit_address_vs_reg): Node /soc/periphs@c8834000/rng has a reg or ranges property, but no unit name

正在驗證是否生成了kvim1.dtb:

ls -ail kvim1.tdb
