3.2.3. Generating DTB
To compile the device tree sources (.dtsi files) into device tree blobs (.dtb files) using the device tree compiler (DTC), execute the
following command under the root directory of Linux:
make <Configuration_File> ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu-
make CROSS_COMPILE=riscv64-linux-gnu- ARCH=riscv dtbs
Tip:
To install
crossbuild-essential-riscv64
package, execute the following command:
sudo apt-get install crossbuild-essential-riscv64
Tip:
<Configuration_File>
: Both
starfive_jh7110_defconfig
and
starfive_visionfive2_defconfig
are applicable.
The following is the example command:
make starfive_jh7110_defconfig ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu-
make CROSS_COMPILE=riscv64-linux-gnu- ARCH=riscv dtbs
Different boards use different dtb files:
