      @george Never mind. It just started working. No clue why, but I'll monitor it and let you know if it starts to get flaky.

      @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?

      @george
      Many thanks for your reply. Is there any guide about how to compile mpp/rknpu module with cool pi kernel?

      And is it possible to compile cool pi kernel 6.1 with panfork?

      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。

      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.
