da1469x

Memfault for the DA1469x Family of Wireless Microcontrollers

This example application shows an integration with Dialog Semiconductors SDK10 for the DA1469x family of Wireless Microcontrollers.

Getting Started

We assume you have a working setup for firmware development on the Dialog DA1469x family of devices:

• have Dialogs SmartSnippets Studio installed
• have installed the latest version of the DA1469x SDK (this example was tested with version 10.0.10.118)

Adding Memfault to the Dialog SDK

Create a directory called memfault in the middleware folder of the Dialog SDK and then clone the memfault-firmware-sdk repository into this folder. The resulting directory structure should look like the following:

<DIALOG_SDK_ROOT>
├── binaries
├── config
├── doc
├── projects
├── sdk
│   ├── bsp
│   ├── free_rtos
│   ├── interfaces
│   └── middleware
│       ├── adapters

└── utilities

Using the demo app

The demo app is compatible with the following DA1469x Development Kit boards:

DA14695 Development Kit USB

DA14695 Development Kit PRO

Building the demo app

The demo application can be built using the Eclipse/GCC (SmartSnippets Studio) toolchain.

First, a few small changes must be made to the Dialog SDK to enable integration of Memfault support. To make these changes navigate to the root of the Dialog SDK and apply the following patches:

git apply --ignore-whitespace ./sdk/middleware/memfault/memfault-firmware-sdk/ports/dialog/da1469x/gnu-build-id.patch

git apply --ignore-whitespace ./sdk/middleware/memfault/memfault-firmware-sdk/ports/dialog/da1469x/freertos-config.patch

git apply --ignore-whitespace ./sdk/middleware/memfault/memfault-firmware-sdk/ports/dialog/da1469x/fault-handlers.patch

Next, open SmartSnippet Studio and import the demo application project, which can be found in the following location:

<DIALOG_SDK_ROOT>/sdk/middleware/memfault/memfault-firmware-sdk/examples/dialog/da1469x/apps/memfault_demo_app

Build the application and then program into the flash memory contained on the Development Kit board.

Running the demo app

The demo app is a simple console based app that has commands to cause a crash in several ways. Once a coredump is captured, it can be sent to Memfault's web services to get analyzed.

Once the DA1469x Development Kit has been programmed, connect to it using a Terminal emulator (such as TeraTerm etc.) at 115200-8-N-1.

NOTE: The DA1469x will enumerate two COM ports when connected to a PC, select the lowest numbered of the two ports when connecting via a terminal emulator.

The following commands are supported by the demo app and can be initiated by sending the command listed:

• crash: Generate different types of crashes with crash [0..3]
• trace: Generate a trace event
• get_core: Get coredump
• clear_core: Clear coredump
• test_storage: Test coredump storage
• get_device_info: Display device information
• reboot: Reboot & record event
• export: Export chunk
• help: show list of available commands
