Flashing SensorIO

SensorIO offers several methods of flashing. Example commands assume that binary is built with Mbed OS, however most of these methods work with any binary built for SensorIO MCU. For all methods SensorIO has to be connected to computer with a USB cable.

Drag & Drop

An easy way to flash new firmware to SensorIO is to drag the binary from build folder (for Mbed OS it is usually located in ./BUILD/SENSORIO/GCC_ARM-DEBUG/ directory) and drop it to SENSORIO removable drive.

Once the copy is complete removable drive will disappear and LD1 LED will blink red and green. After a few seconds removable drive should reappear and SensorIO will start executing new firmware.

Copy from terminal

Of course, Drag & drop can be executed directly from terminal:

cp /path/to/firmware.bin /path/to/SENSORIO

After this command, SensorIO should behave the same way as in Drag & drop. On some operating systems syncing (via sync) and/or explicit SENSORIO removal might be required.

OpenOCD

With a correctly installed OpenOCD binary can be flash from command line:

openocd -f stlink-v2.cfg -f stm32f4x_stlink.cfg -c "program ./path/to/firmware.elf verify reset exit"

This command assumes that SensorIO is connected only via USB cable and flashing is done with on-board ST-Link V2 debugger. For other debuggers (like Segger JLink) configuration files have to be adjusted.

Segger JLink

SensorIO has a separate 10-pin JTAG/SWD header that allows connecting external debuggers to the board. Once Segger JLink debugger is connected to this header and Segger tools are installed, binary can be quickly flashed from terminal:

1. Create a sensorio.jlink command file with following contents (needed only once):

   si 1
   speed 1000
   device STM32F413ZH
   halt
   loadfile path/to/firmware.hex
   r
   g
   q
   

2. Flash new binary with JLink application:

   JLinkExe -commanderscript sensorio.jlink
   

GDB

Binaries can also be flash from GDB prompt. Instructions are on Debugging with GDB page.

Mbed CLI

Mbed CLI

This method will work only for binaries built with Mbed OS and will be available once SensorIO Mbed Enabled certification is complete.

To compile and flash new Mbed OS based firmware to SensorIO execute this command (after proper Code setup):

mbed compile --flash --profile debug.json
