Usage Guidelines
The ping and ping4 commands are the same.
The ping command is a very common method for troubleshooting the accessibility of devices
A timeout is implemented at the bootloader device prompt, that allows the bootloader to poll the TCP stack
every 200 ms. As a result, the bootloader may take up to 200 ms to respond to pings. However, when the
bootloader is downloading a file, and thus actively polling for new packets, it responds to ping quickly.
Examples
