RB3gen2

Enablement

LAVA by default is configured to work with this DUT + LAA setup. If you opt for a different setup you’ll have to change your DUT + LAA device configuration on LAVA.

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

Hardware modification

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

Hardware modification

The DUT will not be automatizable without this modification.

DIP switches

Set the DIP switches as in the picture below.

EDL button

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.

MIB

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

Connections

Configuration

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

Recovery

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

Network

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

Power

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

Serial

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

USB

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

Flashing

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