      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.

      这两个链接是有效的,可以指向源代码。

      以上,帮忙看看我理解和link的是否有问题。还请帮忙看一下这个问题,万分感谢!

      @mxpfeng 可以仿照这个,我理解5b的串口配置应该都差不多。
      https://cool-pi.com/topic/26/coolpi-4b-debug-console串口接线配置说明?_=1715909783162

      然后这种串口转USB的线淘宝上随便两三块钱买一个就好: 【淘宝】https://m.tb.cn/h.g2Q4mDj?tk=K3ZoWF1EmbK CZ3452 「黑PL2303HX USB转TTL RS232模块升级 USB转串口下载线中九刷机线」

      老哥你好,请问你们的自制底板进展怎么样了呢?
      我最近也在为CM5设计底板,不知道这个难度怎么样呢?方便邮箱交流吗?
