Many schemes have been referred to, but nothing has been achieved. Is there a problem with the hardware

Hi,


Please reboot the Raspberry Pi and reset the OpenCR, then try the bringup.

You may also try the timesync for both Raspberry Pi and the Remote PC.

Thanks!

I tried, but it didn't work. We also used the way that the robot is master to start without eliminating the warning. Does this represent a hardware failure
