      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。

      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

      这个export每次启动都需要重新运行的。你可以把这个命令写入/etc/rc.local开机自动运行。

      @etrin
      There are many models in the driver kernel source code of the camera, but this can only ensure that the system recognizes the nodes. For the camera part, it is more important to debug the ISP effect file, which is highly specialized and difficult for those who have not been exposed to it to handle.
