Installing Bridge Tool (bridge-utils) in Buildroot

Navigate to the /OK3568-linux-source/buildroot/output/OK3568 directory and execute the make menuconfig command.

Press the / key to open the search box. Enter the keyword bridge_utils, select OK, and press Enter.

Once the result appears, press 1 to jump to the configuration page.

Select bridge-utils by marking it with y.

Continuously select Exit until you leave the graphical configuration interface. When prompted to save the configuration upon exiting, choose yes.

Switch to the /OK3568-linux-source directory and execute the ./build.sh buildroot command.

You will be prompted that a .config file already exists and asked if you want to regenerate it. Enter n (no); otherwise, your previous configuration will be overwritten.

After compilation completes, a rootfs.ext2 file will be generated in the OK3568-linux-source/buildroot/output/OK3568/images directory. Flash this file individually to the development board.

If the above steps result in an error, your kernel might have been compiled with CONFIG_BRIDGE = n)
