查了下内核代码，看来至少要更新到5.10，Ubuntu 20.04里目前还是5.4。我们想要部署的东西并不支持raspbian。

我需要部署ROS Foxy，目前只能用20.04 LTS，否则需要编译安装。上面链接中只有21.04有Desktop，或者用20.04的Server版手动装桌面环境。因为我希望在树莓派上使用一个较为轻量的桌面，所以选择Ubuntu Mate，其色彩风格和reTerminal也比较搭。其实Ubuntu Mate 20.04官方是有树莓派版的，但没有被列入树莓派的第三方系统清单里。根据他们的Changelog，CM4是支持的。但我刷完第一次启动时，Ubiquity Wizard会崩溃，与之前别人反馈的情况一致。检查了一下system-boot分区，发现并没有CM4的dtb。Ubuntu 20.04的ReleaseNotes说，CM4是在20.04.2中被支持的，而Ubuntu Mate的镜像似乎还停留在20.04.1。因此我换了一种方式来刷机，先刷20.04.2的Server版，然后把system-boot分区内容备份下来。再刷Ubuntu Mate 20.04，刷完将system-boot分区替换为前面备份的内容。之后就可以正常使用了。然后系统所有组件更新到最新后，内核还是5.4，因此只要能将内核更新到5.10，驱动应该就能装了。
