Getting Started
Before getting started, make sure you have a proper nRF Connect SDK development environment. Follow the official Getting started guide.
Initialization
Before initializing, start the toolchain environment:
nrfutil toolchain-manager launch --
To initialize the workspace folder (hello-nrfcloud) where the firmware project and all nRF Connect SDK modules will be cloned, run the following commands:
# Initialize hello-nrfcloud workspace
west init -m https://github.com/hello-nrfcloud/firmware --mr main hello-nrfcloud
cd hello-nrfcloud
# Enable Bosch environmental sensor driver
west config manifest.group-filter +bsec
# Update nRF Connect SDK modules
west update
# Use sysbuild by default
west config build.sysbuild True
Building and running
Complete the following steps for building and running:
Navigate to the project folder:
cd project
To build the application, run the following command:
west build -b thingy91x/nrf9151/ns app
When using the serial bootloader, you can update the application using the following command:
west thingy91x-dfu
When using an external debugger, you can program using the following command:
west flash --erase
Experimental: You can also use pyOCD to flash the nRF9151 SiP using the CMSIS-DAP interface provided by the connectivity bridge firmware.
Important
Do not use pyOCD with JLink probes. Use nRF Util or the West Runner instead.
Note
Sometimes, the nRF9151 SiP is detected as protected and is mass-erased automatically. In that case, simply program the bootloader as well.
Programming
Complete the following steps for programming:
To program the app, run the following command:
pyocd flash build/app/zephyr/zephyr.signed.hex
To program the bootloader, run the following command:
pyocd flash nrf91-bl-v2.hex
To erase the chip including UICR:
pyocd erase --mass
Experimental: You can update the modem firmware using pyOCD.
To do this, use the included nrf91_flasher script as follows:
python3 scripts/nrf91_flasher.py -m mfw_nrf91x1_2.0.1.zip
