This directory contains an implementation of the dependency functions needed to integrate the Memfault SDK into the Zephyr RTOS.
The instructions below assume you have an environment already setup for building and flashing a Zephyr application. If you do not, see the official getting started guide.
The subdirectories within the folder are titled to align with the Zephyr release the porting files were tested against. If no breaking API changes have been made within Zephyr and a different release, the port may work there as well
- Depending on Zephyr version, apply .patch in release directory to Zephyr Kernel. Be sure to use the patch matching the Zephyr version in use.
$ cd $ZEPHYR_ROOT_DIR/
$ git apply $MEMFAULT_SDK_ROOT/ports/zephyr/[v2.0]/zephyr-integration.patch
Note that v2.2_v2.3/coredump-support.patch should be applied for Zephyr 2.2
and 2.3 only.
- Clone (or symlink) memfault-firmware-sdk in Zephyr Project
$ cd $ZEPHYR_ROOT_DIR/ext/lib/memfault
$ git clone https://github.com/memfault/memfault-firmware-sdk.git
- Implement device-specific dependencies.
