This method has been tried before, and as you said, the actual effect can be seen in the Ubuntu system. However, if it is a system with kylin and uos, it must always run in performance mode to run smoothly. We will re evaluate whether to update to the existing kernel configuration. Thank you for your suggestion.

The testing before AX210 was problematic. The most basic BT cannot recognize it, it seems that the firmware version of WIFI is incorrect.

FFmpeg can be changed to a native package. Or using the Chromium browser, the decoding issue of this player has been bothering us for a long time. Take some time later to focus on solving it.

The battery of the RTC connector has a spacing of 0.8mm. From the current phenomenon, it is not that the hardware RTC cannot save time, but rather that the hardware RTC time has not been synchronized with the system. So adding this battery won't make any changes.

对，就是这个地方，自行修改就好了。
