RB3gen2

The RB3gen2 DUT can be automated using the RPi and 96 boards MIB.

Components

The following components are required to fully automate the board:

RPi and 96 boards MIB
Short RJ45 network cable
USB-C male to USB-C male cable
USB-A male to MicroUSB male cable
For the OTG USB-C to MicroUSB connection:
- USB-A male to USB-C male cable
- Micro USB OTG to USB-A Adapter

In order to automate recovery, the DUT hardware should be modified.

Hardware modification

The DUT will not be automatizable without this modification.

Set the DIP switches as in the picture below.

A two-wires cable should be soldered around the F_DL button. This will be used to drive the value high or low to trigger recovery.

The following picture shows how to connect the RB3gen2 board to the MIB.

Connections

Set the voltage level switch on the top of the MIB to 1v8.

Connect the recovery wires cable to the RPi-96 MIB header labeled VBTN_A.

Connect the RB3gen2 network interface to the LAA private network interface.

The RB3gen2 gets power directly from the 96boards header interface.

Connect a USB cable from the carrier board MicroUSB port to USB Port 4 on the SIB as shown above.

Connect the LAA USB OTG port (front facing) to the RB3gen2 MicroUSB port shown in the picture above.

Connect a USB-C cable from LAA Port 1 (facing upward) to the RB3gen2 USB-C port shown in the picture above.
