使用TF卡的话不需要进入UMS模式，直接用读卡器通过etcher软件写就好了。不要用RKD工具。

RE: 刷了系统不启动，怎么回事？posted in Pi 4B
@emtohere
机器默认刷机是使用etcher来刷。不是用RK官方工具，上电多次按开机按键，机器就会进入UMS模式，然后使用etcher软件加载固件，选择设备刷机即可。 -
RE: COOLPI notebook GPU accelerationposted in PI CM5 Laptop
@zehui
The image package we released has already installed the GPU driver by default. Regarding the issue of video playback lag, it has nothing to do with the GPU driver, mainly the VPU. Our image has integrated ffmpeg hardware decoding driver, which can support local video hardware decoding. If it is a network video, due to the system's default browser using snap mode, the hardware decoder cannot be called and can only be decoded through CPU software, resulting in lower smoothness and power consumption. -

I don't have a direct understanding of what happened to this computer, why does it seem to have so many impurities inside.

Hardware versions after V20 can support TYPEC PD charging, but it can only be used when turned on, and only supports adapter charging when turned off.
