    CM5是ARM架构的机器,不能支持X86架构的镜像文件。
    如需安装ARM64架构的UBUNTU22.04镜像,请参考如下文档:

    有一个小问题就是, 插上这个USB网卡之后, 重启会卡在uboot阶段, 原因是这个网卡还有一个usb 磁盘的功能, 从 [04-移植USB无线网卡RTL8XXXU驱动.pdf] 中的dmesg信息中可以看到有一个从usb存储设备切换到网卡设备的信息, u-boot应该是设置了优先从usb存储设备中读取启动文件, 论坛中有一个网友提出这个问题, 待我研究一下u-boot后再来贴出解决方案

    Yes i see it in the schematics now. You are right.

    Usually with rk3588 boards You connect the usb-c port with a usb - usb-c cable to the laptop usb-a port and flash it in maskrom mode.

    My mistake was not to fully study the schematics. In the schematics i see the OTG port is wired to a USB 3 A port.

    I had connected the usb-c to my computer with usb-c to usb A cable and did feed separately 12V to DCIN.

    12V DC in is directly wired to the USB-C port pins. no reverse protection on the usb-c port.

    I added now a diode similar to the DCIN diode. now can never happen again.
    See attached image. this my change for future proof.Bildschirmfoto vom 2024-12-06 00-01-38.png

    I will prepare a updated documentation and send it to You george in a private message so You can update the wiki page and the getting started page.

    CST时间和UTC时间的区别,并不是不能同步。也不是RTC不工作。系统层的问题百度一下。

    @george 终于可以了,把系统删减到14个G,就可以用U盘拷贝了,但是使用脚本的方法还是不可以,后面再研究了。谢谢解答👍

    这是6.1的内核
    已有的程序是不是都要重新编译 链接的第三方库也要更新吗

    如下命令就会生成头文件目录,拷贝到系统usr/src/linux-headers-5.10.110目录即可

    make ARCH=arm64 headers_install INSTALL_HDR_PATH=out_headers/usr/src/linux-headers-5.10.110

    这个要检查一下显示端口VP的配置情况。可以参考notebook的配置。
