on, the 5V Power On LED should light up.
Now to Development
Proceed to Get Started, where Sec

on Step by Step will quickly help you set up the
development environment and then flash an example project onto your board.
Move on to the next sec

on only if you have successfully completed all the above steps.
Configure and Load the Ethernet Example
A er se ng up the development environment and tes ng the board, you can configure and flash
the ethernet/ethernet example. This example has been created for tes ng Ethernet func
