Initial setup to allow boot from USB pendrive

This step is needed in order to enable the HERMES installer to run from a USB pendrive.

First connect a USB keyboard to the radio, and then connect the radio to the network (RJ45) cable with appropriate Internet connection. Then click in the Terminal icon shown in Figure 2.3.

After opening the terminal window, type:

• sudo su
• apt-get update
• apt-get install rpi-eeprom
• raspi-config

At this point the screen shown in Figure 2.4 should appear.

Choose the options of the menu in the following order using the keyboard arrow and Tab keys (as shows in Figures):

• Step 1: Option 6 (Advanced Options)
• Step 2: Option A6 (Boot Order)
• Step 3: Option B2 (USB Boot)
• Step 4: Finish

Then just accept the option to reboot the radio. Now the radio is ready to run the HERMES installer. If needed, in order to turn off the radio, type the following in the terminal window (just after raspi-config):

• halt

And after some seconds, when the screen goes black, turn off the radio (using the power key below the power socket).
