2 Getting started
2.1 Prerequisites
Before you power up your EDB boards for the first time you need the following：
Edge Development Board(EDB)
A 96Boards compliant power supply
2.2 Starting the board for the first time
To start the bard, follow these steps:
Step1. Make sure that the boot switches SW1 is configured as “110”(boot from USB)
Step2. Connector USB cable to UART port (Micro USB)
Step3. Connector power adaptor to DC JACK
Once the board power up, the boot information will be printed on the UART terminal.
Please note that the first boot will take few minutes due to intializaiton.
