      去年同样操作过,没问题,今年买了两台新的CM5,发现运行软件一直警告,无法解决
      详细对比了去年和今年版本的差异,发现去年系统版本是

      Linux coolpi 5.10.110 #2 SMP Sun Dec 22 10:43:41 CST 2023 aarch64 aarch64 aarch64 GNu/Linux

      而新机器的版本是

      Linux coolpi 5.10.110 #2 SMP Sun Dec 22 10:43:41 CST 2024 aarch64 aarch64 aarch64 GNu/Linux

      有新老版本的差异,在尝试各种方式安装kernel无果,尝试备份老机器后,还原到新机器中也无法开机后,重刷了2023版本的系统,重装系统后运行正常。
      最后,需要请教一下,新老版本在preemption model上有无差别?

      @Kanade
      建议切换到6.1的背个版本。默认的代码会生成一个头文件的包,解压到/usr目录即可。

      @nosorrow 你把你更新失败的信息贴上来很难吗?开头忽略的原因有很多,谁知道你是因为源配置错误,还是压根没联网?还是因为用的是国外的源被屏蔽了?

      想解决问题要先把你遇到的问题描述清楚好不好,光在这里有一句没一句的说,大家压根没法帮你。

      你贴个日志或者截图出来行么,还有你更新源之前确保你联网了吗?DNS 配置正常了吗?

      Have you updated your mesa from apt source?
      Like the post you linked said. You have to keep mesa version with coolpi ppa if you want hardware accelaration.

      Kernel 5.10 is using panfork, Which is specific mesa version needed.
      If you want newer version mesa you have to switch to kernel 6.10 and use panthor driver instead.

      @Momo-0 Thank for your reply.
      I think the point is pcie 3.0 /4.0
      maybe pcie 3.0 version nvme ssd should be okay.

      性能肯定会有损失,从目前群控那边的情况来看,没什么太大问题。

      @admin 这个问题之前在另外一款INTEL的相机上没有复现到现象。目前你用的这款暂时没有。

      Meanwhile one can pin PPA to prevent upgrades:

      $ cat /etc/apt/preferences.d/coolpi-ppa-priority Package: * Pin: release o=LP-PPA-george-coolpi-mali-g610 Pin-Priority: 2000 Package: * Pin: release o=LP-PPA-george-coolpi-multimedia Pin-Priority: 2000 Package: * Pin: release o=LP-PPA-george-coolpi-rknpu Pin-Priority: 2000
