debug and upgrade firmware


This article will describe how to debug and upgrade the firmware of NEO V2 pro.

This tutorial is based on SLCAN, the protocol is already supported in Ardupilot firmware; PX4 firmware is not supported at this time.

  • Please connect NEO V2 pro to flight control CAN1 interface.
  • Open mission planner and connect flight controller.

Modify the following parameters in all parameter tables of the mission planner

for CUAV V5+/nano:

  • CAN_SLCAN_CPORT set to 1
  • Serial7_protocol set to 22
  • Reboot flight control

CUAVV5 / NANO / FMUV5 flight control AP4.0 / AP4.0 firmware will have two usb driver ports, one is flight control mavlink output port and one is slcan port; if there are no two ports, please uninstall the driver and reinstall)

For Pixhack series / FMUv2 / FMU V3 / FMU V4 flight control

  • CAN_SLCAN_CPORTSet to 1
  • CAN_SLCAN_TIMEOUTSet to 130000
  • CAN_SLCAN_SERNUM Set to 0
  • Please do not reboot the flight control until your operation is complete.

STM32F4 does not support dual virtual USB ports, so the flight control using STM32F4 processor can only be used for SLCAN after MAVlink transmission is closed; after the above settings, USB becomes SCLAN port; MAVlink transmission will resume after restart.

Debug

Ardupilot supports setting UAVCAN settings through Slcan, such as modifying node ID; enabling / disabling barometer, etc.

MP set

Enable barometer

  • Baro_enable=1(0:disable
  • Reboot

Modify device ID

  • Modify the CAN_NODE parameter

Upgrade firmware

method one:

Firmware upgrade using Mission planner

Firmware download

slcan

  • Click "slcan mode CAN1" on the UAVCAN interface.
  • Click "Update", select NO in the pop-up prompt box (yes is to select online firmware; No select local firmware)
  • Select firmware file

slcan

  • Wait for the writer to complete

method two:

Upgrade with UAVCAN GUI TOOL software

UAVCAN GUI TOOL download

  • Select the device port corresponding to slcan and click "ok"

slcan

  • Click "√"; then double-click on the device information (marked in Figure 2 below)

slcan

  • Click "update firmware", the message box will pop up "yes"
