      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.

      @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」

      1.核心板可以支持PCIE3.0X4 ,目前对应的evb底板只有PCIE3.0X2.
      2.笔记本的SSD接口是M2的PCIEX4接口。

      我所有的内核编译后更新 都是按照下面的步骤来的
      5c151d27-6113-4c02-8d52-22e809e95cfe-image.png
      CM5、cp4都是这样操作的

      内核编译后 都是整个out文件夹打包的
