We decided to update in-tree drivers and Modules, which in hindsight will be nice for upstreaming, but a pain for develpoing (need to keep 3 repos)

You will need the updated HAL module from here And the updated zephyr repo with the I2C driver: here.

We are using an external module (hal_quicklogic), which is linked and built with the flag -DEXTRA_ZEPHYR_MODULES. However although docs mention this module will take precedence above the module intree. However, when building it tries building both and gives errors of redefinition, so you will need to remove the quicklogic hal old module from:

rm -rf zephyrproject/modules/hal/quicklogic

then build it with:

west build -p always -b quick_feather app/ -- -DCMAKE_EXPORT_COMPILE_COMMANDS=1 -DEXTRA_ZEPHYR_MODULES=/path/to/cloned/hal_quicklogic/

This repository contains a Zephyr example application. The main purpose of this repository is to serve as a reference on how to structure Zephyr-based applications. Some of the features demonstrated in this example are:

• Basic Zephyr application skeleton
• Zephyr workspace applications
• Zephyr modules
• West T2 topology
• Custom boards
• Custom devicetree bindings
• Out-of-tree drivers
• Out-of-tree libraries
• Example CI configuration (using Github Actions)
• Custom west extension

This repository is versioned together with the Zephyr main tree. This means that every time that Zephyr is tagged, this repository is tagged as well with the same version number, and the manifest entry for zephyr will point to the corresponding Zephyr tag. For example, the example-application v2.6.0 will point to Zephyr v2.6.0. Note that the main branch always points to the development branch of Zephyr, also main.

Before getting started, make sure you have a proper Zephyr development environment. Follow the official Zephyr Getting Started Guide.

The first step is to initialize the workspace folder (my-workspace) where the example-application and all Zephyr modules will be cloned. Run the following command:

# initialize my-workspace for the example-application (main branch)
west init -m https://github.com/zephyrproject-rtos/example-application --mr main my-workspace
# update Zephyr modules
cd my-workspace
west update

To build the application, run the following command:

west build -b $BOARD app

where $BOARD is the target board.

You can use the custom_plank board found in this repository. Note that Zephyr sample boards may be used if an appropriate overlay is provided (see app/boards).

A sample debug configuration is also provided. To apply it, run the following command:

west build -b $BOARD app -- -DOVERLAY_CONFIG=debug.conf

Once you have built the application, run the following command to flash it:

west flash
