This issue was also tested in version 22.04 due to compatibility issues with hardware decoding of RK in firefox in deb format. The use of Snap version cannot call the hardware decoder of RK, but there is no crash issue with video soft decoding, or although the local browser of Chromium cannot call the hardware decoder of RK yet, the software decoder can meet daily use.

@plumlis
First of all, thank you very much for the support of your Coolpi product.
Fedora's image will release a basic version of the image in the near future, and then optimize support for GPU, VPU, and more.
We will evaluate the support for EDK2 in the near future. The current main focus is on adapting to the 6.1 kernel.

@yaitoro
Yes, this is the official store address.

@plumlis
对，就是这个地方，自行修改就好了。

@happyday
需要从github下载代码到机器，然后修改，编译，替换。

@happyday
你要修改dts文件，然后再编译生成dtb，再替换。

这个看log信息是EDID的IIC通讯出错。可以清理一下金属指，然后重新安装核心板。

@plumlis
Refer to the disassembly video below, the screw lengths are differentiated, please note.

Just confirmed with the warehouse that there are delivery cables together. Please check carefully.
The SSD part has not undergone comprehensive testing yet, so it is currently difficult to recommend specific models. We will update it after the code is completed. Thank you for your support.

• 32+64 configuration is emmc, 32+1T is nvme
• At present, the system only supports booting from emmc, and the machine does not have a TF card interface. After upgrading the NVME driver in uboot, it can be booted from NVME.
• The typec interface can support PD charging, but currently it can only be used when turned on. The shutdown state can only be charged through a DC adapter.
• The current shipped versions are all V20 motherboards.
• We can provide models of touch screens that you can purchase through Taobao or other platforms. The touch model requires replacement of the ribbon cable. If you are in China, I can give you a free one as a gift.
• The model of the touch screen is: BOE NV140FHM-T07

@plumlis

• Thank you very much for your interest in Coolpi laptops.
• We have been working hard to adapt the display screen. Currently, there are two complete models with a resolution of 1080P, one of which supports touch function. Last month, we adapted a model with a 4K resolution, which has no problem with the function. However, there is some interference in the structure, so it cannot be used temporarily. We will continue to adapt to more models in the future, and will eventually announce them in the community in the form of a support list. Thank you for your support.
• By the way, there are currently two specifications of ribbon cables: eDP 30 and eDP 40.
• We can support users to replace their LCDs themselves, and we will provide a video tutorial, provided that they have some hands-on skills.
• The adaptation of the operating system is shown in the following figure and will continue to be updated.

1.RK3588 MALIG610 can only support OPENGLES-3.2, I am not sure if this 4.5 is compatible. The GPU driver of Coolpi will be switched to Panthor in the future.

2.Confirm the hardware version of the laptop. If the hardware is V10 and then update the V20 image, there will be a power option issue.

@plumlis
The current default model for 1080P LCD is NV140FHM-N42,The specification parameters are as follows：

@plumlis
The machine can support sleep mode by default. If the laptop screen is closed, the machine will automatically enter sleep mode.
The battery is of 38WH specification, with a nominal 5000mAh/7.6V. The power consumption of the entire machine in sleep mode is 8G+64G 7.4V/6MA, 32G+64G 7.4V/8MA, so the theoretical longest sleep time is 833 hours, exceeding one month.

@maifengw2024
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。

@guyii
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

@plumlis
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

        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
                ];

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
