An assertion error occurred in the kernel. Does it affect normal use?

另外也請你調高power mode進行測試

Hi，WayneWWW：
我这里现在没有4K的显示器，我使用p3509重新刷了一次程序，现在xrandr查询显示是hdmi了

nvidia@nvidia-desktop:~$ sudo xrandr 
[sudo] password for nvidia:

10W已经是orin nano最高的模式了：

现在查询hdmi显示正常后，还是有assert异常：

我发现使用p3509烧写完后，用作烧写的usb口在设备启动后无法被正常识别为usb网口了，不知道是否是需要配置。

  1. 那請無視那個assertion. 對功能不會有影響

  2. 我发现使用p3509烧写完后，用作烧写的usb口在设备启动后无法被正常识别为usb网口了，不知道是否是需要配置。

是的, 我前面已經說過了, 請嘗試去理解device tree怎麼寫. 不是一股腦的就燒board config. 你這樣燒當然會有device tree設定不符合預期. 3509跟3768又不是同樣的硬體.
