First of all, connect the computer to the device that can access the Internet with a network cable (the router I am directly connected to, the current PC uses wireless), so that in order to solve the situation that the wireless network card used by the computer to surf the Internet does not work, the development board is also connected to the router with a network cable.

Now my situation is:

First, the virtual machine is set in bridging mode, bridging to the wireless network card, surfing the Internet is normal.

Second, the IP of the virtual machine is 192.168.1.105.

Third, uboot ipaddr=192.168.1.104,serverip=192.168.1.105 (Note: this IP is the IP of the virtual machine, because the tftp download image is downloaded from the tftp built on the virtual machine).

At this time, in the uboot command mode, the development board can ping the virtual machine and download the image file with tftp.

As for the mutual ping between the development board, virtual machine, and PC:

First, the development board can ping PC and virtual machine.

Second, the virtual function ping can communicate with PC, but ping can not communicate with the development board.

Third, PC can ping the virtual machine, but ping does not have access to the development board. (I guess it is because the computer's wired network card is not working properly that the ping is not verified.)

Note: the premise of the above mutual ping is that the firewall is turned off, otherwise the ping may be blocked, and the IP should be set in the same network segment.

The above are the records of the results of individuals who encounter such problems and solve them, and there are still problems, for reference only.
