Avenger96 interfaces with Bosch Sensor Mezzanine

Overview

TBD

Requirement

Hardware

• Avenger96 - link
• Bosch Sensor Mezzanine - link
• UART Serial - link or any other USB-to-Serial supporting 1.8V
• 2 micro USB cables
• SD card, minimum 8GB
• Power supply: recommended 12V/2A

Software

• PC with Linux operating system
• STM32CubeMX
• STM32 System Workbench
• Terminal program

Bring up the application

• Power up the board
• Connect the board to the PC with USB-to-Serial interface and start the terminal program

Building the ethernet interface between the board and PC (execute only once)

• On the linux machine, type:

> sudo gedit /etc/network/interfaces 

• Add the Ethernet interface:

allow-hotplug ens35u1
iface ens35u1 inet static
address 192.168.7.1
netmask 255.255.255.0
network 192.168.7.0
gateway 192.168.7.1

• Disable networkManager for all Ethernet-to-USB:

> sudo gedit /etc/NetworkManager/conf.d/stm32mp-otg-eth.conf 

• Add those lines below:

[keyfile]
unmanaged-devices=interface-name:ens35*;
interface-name:usb*

• Reboot linux machine
• After rebooting, on the linux machine we can verify the connetion by:

> ping 192.169.0.2

• On the Avenger board, we can also verify the connection by:

> ping 192.168.0.1

Flashing the application

• Clone the repository
• Import the project into system workbench and rebuld it. There should be no error and some minor warnings
• Flash the application into the Avenger96
• If the application have not started yet, please go to:

> cd /usr/local/projects/Avenger_Bosch_Mezz/
> ./fw_cortex_m4.sh start

• Activate the co-proc messaging:

> stty -onlcr -echo -F /dev/ttyRPMSG0
> cat /dev/ttyRPMSG0 &

• The sensor data can be read by using this command:

> echo "read data" > /dev/ttyRPMSG0

• The response message follows:

> W: 0.999  X:-0.025  Y:-0.027  Z: 0.021

• You can also test the LED by issueing the command:

> echo "LED ON" > /dev/ttyRPMSG0
> echo "LED OFF" > /dev/ttyRPMSG0

• Application can be stopped by:

> ./fw_cortex_m4.sh stop

Starting from scratch
