@Jake 这个需要把内核的头文件编译生成DEB包，然后系统上安装。

george

@dff 可以通过MIPI-RX接口链接MIPI相机。

george

@shengxia 昨天有提交了一个USB3.0的修改，你可以同步最新代码测试。我手上几个盘都可以使用。

george

@yushaotai 还有就是EDIE读取回来的时序，要和实际写到代码里边的数组一致，否则也不能正常显示的，你需要什么分辨率？

george

@yushaotai 你也可以现在linux上面修改测试，正常底层是一样的，没有区别的。

george

@yushaotai 这个之前有发过一个linux的，按照那个文档修改就好了。

@zensation
If you need to use PWM function, it is recommended to use PIN12 (PWM3-M3). This port defaults to the pull-up port, and you can increase the resistance to ground by 2K. The default level can be reduced to below 0.6V. If you need GPIO function, except for PIN3 PIN5 PIN32 PIN40 PIN8 PIN10, all other IOs can use pull-down resistors to change the default level.

@零度灬救赎交叉编译环境内核的代码里边已经集成，直接运行编译脚本即可：
build-kernel.sh

george

@dbtech You can download it from the following website:
https://coolpi-my.sharepoint.com/personal/coolpi_coolpi_onmicrosoft_com/_layouts/15/onedrive.aspx?ga=1&id=%2Fpersonal%2Fcoolpi_coolpi_onmicrosoft_com%2FDocuments%2Fcoolpi%2Fcoolpi%2FCoolPi 4B%2Fubuntu

george

@jugg weson和这些没有关系的，他只是一个显示界面而已。系统的gst、ffmpeg都可以支持的。

george

@jugg buildroot是weson实现的。可以尝试。

george

@jugg 这个是ubuntu自身的问题，不是底层系统问题，如果应用一定要2屏以上复制，可以考虑使用weson桌面实现。

@zensation
Software modification pull-down:

specifies that the default pull-down of GPIO needs to be modified in the kernel DTS file, path:/arch/arm64/boot/dts/rockchip. After the modification is completed, compile and generate a DTB file, and then replace it.

Hardware modification pull-down:

You can change the default pull-down situation of IO by connecting a pull-down resistor to GPIO. The default pull-up change is to connect a 2K resistor to the GND network, and the default pull-down change is to connect a 4.7K resistor to a 3.3V power supply.

@diudiutong 这个看log是网络连接问题，默认的镜像已经集成GPU驱动。

george

@bbsvs2000 有支持

george

@SSHLY 这个是PADS格式的。不是AD.

george

@jugg 这个还是从应用软件想办法解决，底层暂时没有可以修改的。可以参考一下MPV播放器的源码实现。

george

@jugg 默认MPV播放器是否有问题

george

@jugg 这个只需要替换内核就可以了。跟之前其它FS的方法是一样的。

george

@jugg 你是什么机器CP4B/CM5，需要接什么屏幕？

george

@jugg 更新系统不会破坏loader文件。不需要重新升级loader。

george

@jugg 自己修改一下fstab。

george

@zensation
The current operation method does not support configuring the up and down status. If you need to modify the up and down status of GPIO, you can use DTS's PINCTRL to achieve it.

	lcd {
		lcdpwr_en: lcdpwr-en {
			rockchip,pins = <1 RK_PC4 RK_FUNC_GPIO &pcfg_pull_down>;
		};
		bl_en: bl-en {
			rockchip,pins = <4 RK_PA3 RK_FUNC_GPIO &pcfg_pull_none>;
		};

@zensation
Can you be more specific about which commands are not working.

george

@reddfoxx
Thank you for your suggestion. As I haven't paid too much attention to ARMBIAN, I have only tried to develop the corresponding firmware. Currently, my main focus is on Ubuntu Debian Android and the optimization and expansion of the upper and lower layers of the system. You can try adding the Armbian mainline in the future.

george

@jugg 目前仅支持三屏扩展的方式，mirror暂时不支持。框架本身就不支持。
