@hangman tf卡优先级高于EMMC。

@hangman etcher会格式化，不需要单独处理。

如下脚本放置到U盘或者TF卡中，然后运行就会导出EMMC的系统。导出的镜像可以重新烧录到EMMC或者TF卡中。

!# /bin/sh

IMAGE_NAME="$(date "+%Y%m%d")-rootfs.img"
IMAGE_SIZE=8192
LOOP_NUMBER=$(losetup -f)

echo "01:remove firstrun"
rm /var/lib/misc/firstrun
echo "02:Establishing a mount directory"
mkdir ./mnt
echo "03:dd image file"
dd if=/dev/zero of=./$IMAGE_NAME bs=1M count=$IMAGE_SIZE

@阿里 如下图所示，不要接错了。可以参考EVB的原理图USB的连接方法。

@airobot机器人开发 谢谢分享。

@阿里 这里标识有问题，下载接口是OTG0 DM DP，还有VBUS-DET，WIKI上已经更新了修改以后的文件。注意下载比对。

@anernest Please upload a copy of dmesg information. Thank you.

• By default, the Cockpit package is included in the Ubuntu 22.04 default repository. You can install it by running the following command:

    sudo apt-get install cockpit -y

• After installing Cockpit, run the following command to install the Podman module:

    sudo apt-get install cockpit-podman -y

• After installing Cockpit, start the Cockpit service and have it start when the system reboots:

    systemctl start cockpit
    systemctl enable cockpit

• You can also use the following command to check the status of Cockpit:

     systemctl status cockpit

• You should see the following output:

• At this point, Cockpit has started and is listening on port 9090. You can use the following command to view:

     ss -antpl | grep 9090

• You should see the following output:

     LISTEN 0      0                  *:9090            *:*

• Configure a UFW firewall and open port 9090

• Now, open a web browser and use the URL https://your-server-ip:9090 Access the Cockpit web interface. You should see the Cockpit login page:
  
  

@jugg 文件系统损坏了！该刷机就刷机！当让也可以用TF卡或者U盘启动，备份数据。

@jugg
尝试把流控关闭。

@airobot机器人开发 好的！正常编译完内核以后需要把modules.tar.gz 解压到文件系统的/lib 目录，这里边主要是一些驱动的ko文件。

@qys2022 不使用NC就好了。不用接高或者低

@airobot机器人开发 系统镜像做到TF卡或者U盘里边，默认TF卡或者U盘启动优先级高于EMMC，系统启动后手动挂载EMMC分区就可以导出数据了。

@Momo-0
Thank you for sharing. If you have any questions during use, I hope you can raise them. Thank you very much for your support.

@阿里 系统镜像可以重新刷一下，如果有修改导致图像界面启动不了的话。

@阿里 这个系统已经正常启动。两个HDMI接口可以交换测试。

@阿里 跑的什么系统，另外注意电源功率是否够。
