Update USB and Ethernet controller firmware

​

Introduction

A firmware update to the USB controller may solve USB or Ethernet connectivity issues on the Dragonwing RB3 Gen 2 device.

​

Prerequisites

• Ensure that you upgrade the software as described in Update the software before updating the Renesas firmware.
• Ensure that you install the ADB tool. Fastboot comes installed along with it.
• Connect the device to the Ubuntu host computer using a USB Type-C cable.

​

Procedure

• Register and sign in to Renesas.
• Download the firmware from Renesas.
• Rename the downloaded firmware file to renesas_usb_fw.mem.
• Connect the device to the host computer using ADB.
• Push the firmware to the device using one of the following commands:
  adb push renesas_usb_fw.mem /lib/firmware
  
  OR
  scp renesas_usb_fw.mem root@<ip-address-of-device>:/lib/firmware
  
  Sample command

  scp renesas_usb_fw.mem root@10.92.175.138:/lib/firmware
  
• Activate the firmware using either of the following options:
  • Reboot target for USB type A ports.
  • Manually bind the Renesas xHCI driver:
  echo "0001:04:00.0" > /sys/bus/pci/drivers/xhci-pci-renesas/bind
  
• Retrieve the device ID:
  sh-5.3# lspci
  
  In the following sample output, 0001:04:00.0 is the device ID:
