      @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?

      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。
