20240924给荣品RD-RK3588-AHD开发板刷Rockchip原厂的Buildroot
2024/9/24 16:38

1、默认选择RK3588S编译：【EVB1】
viewpro@viewpro-ThinkBook-16-G5-IRH:~/rk3588s_20230620$ 
viewpro@viewpro-ThinkBook-16-G5-IRH:~/rk3588s_20230620$ ./build.sh lunch
4. rockchip_rk3588s_evb1_lp4x_v10_defconfig
Which would you like? [1]: 4
viewpro@viewpro-ThinkBook-16-G5-IRH:~/rk3588s_20230620$ ./build.sh 

刷机的时候很容易发现经典的单双RK806电源问题！

2、可容易发现，DTS目录中，单电源方案有：tablet、EVB4和EVB8。
更具经验，但是linux下的方案只有rk3588s-evb4-lp4x-v10-linux.dts。

rk3588s-tablet-v10.dts
rk3588s-tablet-v11.dts
rk3588s-tablet-rk806-single-v10.dts

rk3588s-evb1-lp4x-v10-linux.dts
rk3588s-evb1-lp4x-v10.dts  rk3588s-evb1-lp4x.dtsi  rk3588s-rk806-dual.dtsi

rk3588s-evb2-lp5-v10.dts  rk3588s-evb2-lp5.dtsi  rk3588s-rk806-dual.dtsi
rk3588s-evb2-lp5-v10-linux.dts

rk3588s-evb3-lp4x-v10-linux.dts
rk3588s-evb3-lp4x-v10.dts  rk3588s-evb3-lp4x.dtsi  rk3588s-rk806-dual.dtsi
rk3588s-evb3-lp4x-v10-sii9022-bt1120-to-hdmi.dts
rk3588s-evb3-lp4x-v10-nvp6158-ahd-to-bt1120.dts
rk3588s-evb3-lp4x-v10-rk630-bt656-to-cvbs.dts

rk3588s-evb4-lp4x-v10.dts  rk3588s-evb4-lp4x.dtsi  rk3588-rk806-single.dtsi
rk3588s-evb4-lp4x-v10-linux.dts

rk3588s-evb8-lp4x-v10.dts  rk3588s-evb8-lp4x.dtsi  rk3588-rk806-single.dtsi

3、使用EVB4的DTS，编译打包刷机之后可以进buildroot，但是HDMI没有显示。
断电/掉电之后在开机，连Buildroot也无法进入了。。
Z:\rk3588s_20230620\device\rockchip\.chips\rk3588\rockchip_rk3588s_evb1_lp4x_v10_defconfig
RK_KERNEL_DTS_NAME="rk3588s-evb1-lp4x-v10-linux"
RK_USE_FIT_IMG=y

修改为：

#RK_KERNEL_DTS_NAME="rk3588s-evb4-lp4x-v10-linux"

很容易发现荣品对Rockchip原厂的SDK进行了深度定制/订制！
连DTS都新建了目录。确实和以前的/原生的DTS有所区别。

简单粗暴的解法，将所有的DTS/DTSI文件都放回原来的位置，如果出现路径依赖的问题，改！
