Firmware for Arduino Nicla Voice board
This project uses the arduino-cli compiler to build & flash new firmware. Windows users also need Arduino IDE (tested with v1.8.15).
The script will verify if all needed libraries and the samd core is installed and install them if needed. If you prefer to do this step manually, follow the step in the next chapter.
For building the project:
- For audio support, use:
./arduino-build.sh --build
- For IMU sensor support, use:
./arduino-build.sh --build --with-imu
For flashing use:
./arduino-build.sh --flash
You can also do both by using:
./arduino-build.sh --all [--with-imu]
- Run
update_libraries_windows.batscript to install Arduino libraries. - Note: the firwmare shall be located in a folder named
firmware-syntiant-nicla-internal - Note: Install version 0.21.0 of the
arduino-cli. Newer version are not supported yet. Download the arduino-cli. For further instructions, see Arduino cli installation
For building the project:
- For audio support, use:
./arduino-win-build.bat --build
- For IMU sensor support, use:
./arduino-win-build.bat --build --with-imu
For flashing use:
./arduino-win-build.bat --flash
You can also do both by using:
./arduino-win-build.bat --all [--with-imu]
In order to be fully operative, the external flash of the board should be populated with:
- mcu_fw_120_v91.synpkg
- dsp_firmware_v91.synpkg
- ei_model.synpkg
There are 4 scripts for each supported OS:
- flash_ runs the mcu and the model flash script.
- flash__mcu flash just the firmware for the mcu.
- flash__model flash, if they are not present on the board, the NDP fw and the NDP dsp fw, and update the model.
- format__ext_flash erase the external flash.
where os can be linux, mac or windows.
To install the required dependencies, run the install_lib script for your os; you need to run isntall_lib just once.
The script to update the model uses one python package:
