4KP60必须要用4line 的MIPI，2line的跑不满。请悉知。

@maifengw2024
理论计算2line 的MIPI通道是跑不到4KP60的。
总带宽：3840x2160x60x10x1.3=6.47G，单line的速率3.2G以上。勉强可以做到4KP30或者更低。确认一下是否能满足要求。

@maifengw2024
1.增加IMX477R的驱动
2.系统层ISP库增加SENSOR对应效果的JSON文件。

@maifengw2024
暂时不支持IMX477R这个型号。

Firstly, create a system image to a USB drive or a portable hard drive using the etcher. Then, insert the computer and start it up. The machine will first start from the USB drive. After entering the system, format the EMMC using the following command to enter UMS mode again.

sudo mkfs.ext4 /dev/mmcblk0

At present, the 4K monitor is still in the debugging stage. We will compile a list of screen supports in the future, and the corresponding ribbon cables will also be listed in online stores. Please follow the community, thank you for your support.

@plumlis
At present, laptops support lid sleep mode. When the screen system of the laptop is closed, it will automatically enter deep sleep mode. To open the screen, you need to manually press the power button to wake up the machine again. Please be informed. This is different from the S2 S3 on the X86 platform.

@Twsuts-0
先把硬盘格式化为EXT4或者NTFS格式，然后就可以正常识别了。

sudo mkfs.ext4 /dev/sd*
或者
sudo mkfs.ntfs /dev/sd*

@reallaowu
This phenomenon still doesn't work properly when booting from USB, you can try it a few more times.

@happyday
你是要用笔记本连接其它设备，还是其它设备远程登陆笔记本？是远程桌面还是SSH登陆？

@reallaowu
The image is created using the ETCHER tool to a USB 2.0 USB drive, then inserted into the computer's USB interface, and turned on. The machine will boot from the USB 2.0 USB drive. After entering the system, the EMMC can be formatted using the following command.

sudo mkfs.ext4  /dev/mmcblk0

If this method still cannot boot properly, you need to dismantle the machine and force it to enter MASKROM mode to format the EMMC storage. Try following the above method first, and if it still doesn't work, I will send you a mandatory formatting method.

• First, synchronize the code using the following command:

https://github.com/yanyitech/coolpi-kernel.git

• Open the corresponding DTS file and modify the DSI related configuration

vim arch/arm64/boot/dts/rockchip/rk3588-cpcm5-evb.dts

&dsi0 {
        status = "okay";
        //rockchip,lane-rate = <1000>;
        dsi0_panel: panel@0 {
                status = "disabled";
                compatible = "simple-panel-dsi";
                reg = <0>;
                backlight = <&backlight>;
                reset-delay-ms = <10>;
                enable-delay-ms = <10>;
                prepare-delay-ms = <10>;
                unprepare-delay-ms = <10>;
                disable-delay-ms = <60>;
                dsi,flags = <(MIPI_DSI_MODE_VIDEO | MIPI_DSI_MODE_VIDEO_BURST |
                        MIPI_DSI_MODE_LPM | MIPI_DSI_MODE_EOT_PACKET)>;
                dsi,format = <MIPI_DSI_FMT_RGB888>;
                dsi,lanes  = <4>;
                panel-init-sequence = [
                        05 78 01 11
                        05 00 01 29
                ];

                panel-exit-sequence = [
                        05 00 01 28
                        05 00 01 10
                ];

@Au
Q1:请问咱们有可以参考的YOLOv5_obb模型的RKNPU的C++后处理程序吗？旋转检测的后处理比较复杂，我们自己开发时间有些长，谢谢！
A: 目前没有，暂时也没有这方面的开发计划

Q2:YOLOv5_obb模型的RKNPU的后处理可以通过RGA、NPU等加速吗？
A: 线性操作可能是可以的；逻辑操作（如NMS）目前均无法加速

I have arranged to list it on AliExpress soon. Thank you for your support.

The DSI node can be enabled as follows.I didn't understand which GPIO C0 C1 corresponds to, please indicate.

@Rock
You can download the image again to the 24.04 system directory. If you downloaded to 22.04 before, you must first mount mmcblk0p2 to the system and then find the image you downloaded earlier in the corresponding folder.

@happyday
1,这版镜像是带桌面的吗？为什么我的没有出现桌面，只能在串口启动开发板，并通过命令操作？如何调出桌面
这个是带桌面的镜像，默认是hdmi输出，你也可以尝试使用其它镜像，比如22.04，看是否有输出，排除硬件问题导致。
2,通过笔记本电脑可以运行镜面桌面吗，还是只能通过单个的显示屏？
是可以远程连接的，但是前提是机器要开启DSI的终端。系统至少要有一个显示端口处于激活状态。
3，如果开发板带EMMC，是不是将镜像烧录到SD卡后，上电后，镜像会存储到EMMC中，SD卡在上电一次后就可以拔出了吗？
开发板带EMMC，镜像就可以通过上层的USB3.0接口刷入，不需要TF卡。
4，开发板关机，是向串口发送命令吗？
有图形界面可以使用图形界面的关机对话框，串口shell也可以关机。

@Ranomez
You can try compiling the source code on a 32-bit system. You may encounter some package compatibility issues.

@kingpin1cn
如果机器是板载的EMMC模组，可以尝试进入UMS模式，通过ETCHER软件刷机。

@markerrors
DTS文件里边使能DSI0的节点，需要多大分辨率就配置多大，这样就可以远程登录桌面了。

@Twsuts-0
你仔细看一下我们的那个脚本，实际上思路很简单，先dd一个img镜像（大于你的FS的大小），然后把这个镜像分为2个区（一个放boot，一个放FS），再然后把镜像挂载到系统，再把系统对应分区直接复制到镜像分区，然后做一些文件系统检查的工作即可。

@kingpin1cn
需要插入到上面的那个USB3.0端口，当然也可以使用在线刷机。

@Twsuts-0
我们一直都是使用这个方法和脚本备份的，没有发现有什么问题的。你要做分区备份肯定不能在当前分区操作的。

@Twsuts-0
这个最好使用移动硬盘备份，很多U盘在长时间大数据量写入的时候容易出错。这种情况之前也又遇到过。

@Momo-0
At present, PD charging only supports charging when turned on, and does not currently support charging when turned off. The protocol only supports TYPEC PD format and does not support QC standards. So you need to use an adapter with TYPEC interfaces on both ends as shown in the following figure:

@Rock
Due to compatibility issues with USB3.0 devices, you can try booting with USB2.0 devices.

@traceback
We will update the kernel to 6.1 soon, please be patient.

@markerrors
ubuntu是无线也不行吗？没有看明白。

@Momo-0
The cloud storage provides a 22.04 image, which you can download and upgrade.

@markerrors ubuntu是否正常？
