/proc/decive-tree 目录
在linux中查看使用哪个dtb，在u-boot源码里搜索
grep -nR “rk3566-orangepi-3b.dtb”*
编译特定的dtb
在kernel目录下， make ARCH=arm64 dtbs
例如 make ARCH=arm64 rockchip/rk3566-orangepi-3b-v2.dtb
make ARCH=arm64 rockchip/rk3566-orangepi-3b-v2.dtb
生成的dtb在/sdk/orangepi-build/kernel/orange-pi-5.10-rk35xx/arch/arm64/boot/dts/rockchip 目录下，替换掉开发板的即可
scp /home/yue/sdk/orangepi-build/kernel/orange-pi-5.10-rk35xx/arch/arm64/boot/dts/rockchip/rk3566-orangepi-3b-v2.dtb orangepi@192.168.0.
105:/boot/dtb/rockchip
//将编译的dtb传输到开发板上
#!/bin/bash
chmod 777 /home/yue/sdk/orangepi-build/kernel/orange-pi-5.10-rk35xx/arch/arm64/boot/dts/rockchip/rk3566-orangepi-3b-v2.dtb
scp /home/yue/sdk/orangepi-build/kernel/orange-pi-5.10-rk35xx/arch/arm64/boot/dts/rockchip/rk3566-orangepi-3b-v2.dtb orangepi@192.168.0.105:/home/orangepi
//将开发板home目录下的dtb放到正确的未知
#!/bin/bash
chmod 777 ./rk3566-orangepi-3b-v2.dtb
sudo cp ./rk3566-orangepi-3b-v2.dtb /boot/dtb/rockchip
