@jugg 尽快确认回复你，之前没有和DSI一起，驱动部分可能会有部分修改。

@jugg 你现在想做的是3屏同显，1个MIPI 1个HDMI 1个MINIDP,我理解的有没有问题？

@jugg 显示框架改到X11测试，再登录界面选择：

@wuming 按照如下方法操作，格式化EMMC
1.按住中间的loader按键同时短按复位按键，机器就会进入maskrom模式，如下图所示：

2.选择loader文件，选择EMMC，点击download，等待完成以后点击Eraseall。即可完成EMMC擦除。

3.短按复位按键，快速按三次pwr按键，机器就会进入MSC模式

4.使用etcher选择固件和MSC设备烧录即可。

@wuming 下图如下固件测试，已经集成IMX219单摄的驱动和基础配置。

    add some wifi modules to cp4b

@jugg 请更新代码，已经提交了cp4b的配置。

@wuming 今天我会上传一个最新的镜像文件，默认支持IMX219单摄像头，你烧录以后再同步测试。先确认机器是否能正常进入MSC模式？

@wuming 上电开机，快速按三次pwr按键机器进入MSC模式，就可以使用etcher刷系统了。

@wuming 这个IMX219是有打开的。上层直接用QV4L2打开video11节点就好了。

@jugg 4b更新代码以后USB接口的WIFI模组都可以支持。

Note: Models are continuously updated

@jugg 可以提交一下如下log信息，看IMX219有没有正常识别到。

@wuming 确认DTS文件有如下配置，如果没有就更新代码：

Test tools

Canutils is a commonly used CAN communication testing toolkit that includes five independent programs: canconfig, candump, canecho, cansend, and cansequence. The functions of these programs are briefly described as follows:

• canconfig
  The parameters used to configure the CAN bus interface mainly include baud rate and mode.

• candump
  Receive data from the CAN bus interface and print it in hexadecimal format to standard output, or output it to a specified file.

• canecho
  Resend all data received from the CAN bus interface to the CAN bus interface.

• cansend
  Send the specified data to the specified CAN bus interface.

• cansequence
  Automatically repeat the increment number to the specified CAN bus interface, or specify the receive mode and verify the received increment number.

• ip
  Configuration of CAN baud rate, functions, etc.

Common commands

• Query current network devices:

ifconfig -a

• CAN start:

ip link set can0 down  //Close CAN
ip link set can0 type can bitrate 500000 //Set bit rate of 500KHz:
ip -details -statistics link show can0 //Print can0 information:
ip -details -statistics link show can0 //Start CAN:

• CAN sending:

Send (standard frame, data frame, ID: 123, date: DEADBEEF):

cansend can0 123#DEADBEEF

Sending (standard frame, remote frame, ID: 123):

cansend can0 123#R

Send (extended frame, data frame, ID: 0000123, date: DEADBEEF):

cansend can0 00000123#12345678

Sending (extended frame, remote frame, ID: 0000123):

cansend can0 00000123#R

• CAN reception:

Start printing and wait for reception:

candump can0

@wuming dmesg打印一份传上来，这种情况是没有识别到摄像头模组。

@jugg 这个版本还没有增加。

@george 如下代码测试正常：

import cv2 as cv2
cap = cv2.VideoCapture(11)
while True:
    success, img = cap.read()
    cv2.imshow("Video", img)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break
cap.release()
cv2.destroyAllWindows()

@Mz3D-0 It can be launched in mid June and is currently in the debugging stage.

@wuming 先使用QV4L2打开video11节点，系统默认已经安装。

@jugg 图片使用的是AP6275S就是WIFI6的模组

• Picture first
  
  
  

• 4G-32G Memory Capacity Replacement.

• The WIFI module is replaceable and supports models such as 2.4G 5G WIFI6.

• EMMC module supports up to 256G.

@Mz3D-0 Both CP4 and CM5 already support 32G/256G configurations and can be purchased directly from an agent.

@jugg 22.04对应的版本如下：

sudo apt-get install ocl-icd-libopencl1=2.2.14-3

@wuming 内核同步到最新，确认系统可以生成video11节点。mipi摄像头默认的设备节点是video11
然后运行如下命令更新ISP库：

sudo apt-get update
sudo apt-get dist-upgrade

@jugg ubuntu的系统版本？

@jugg 你的系统版本是多少？

@jugg 按照如下命令回退包版本：

sudo vim /etc/apt/sources.list.d/george-coolpi-ubuntu-mali-g610-lunar.list

屏蔽掉如下安装源：

sudo apt-get update
sudo apt-get install ocl-icd-libopencl1=2.3.1-1
sudo apt-get install ocl-icd-opencl-dev
sudo apt-get install ocl-icd-dev

@jugg 这几个是FFMPEG的解码库？贴出来你的文件看一下。

@JohnConnor 飞线可以。
