Develop

This section will introduce the relevant content in development.

Build

Visual Studio 2019 or later version is recommended for building. Currently, you can only build the elaphure.Wpf project, and other dependencies will be built automatically.

Architecture

The following diagram shows the system architecture of elaphureLink.

elaphureLink consists of the following 5 main components:

• AGDI elaphureLinkAGDI is application generic debug interface of elaphureLink. It is the bridge between Arm Keil µVision and RDDI connection. It performs the interface to all basic debugger features, allows complex breakpoints, flash programming or access to system memory. Some of the debug settings and GUI in µVision are also provided by it.

• RDDI elaphureLinkRDDI is remote device debug interface of elaphureLink that allow remote DAP device communicate with the debug interface. It converts the requests into standard CMSIS-DAP commands and communicates with the proxy.

• Proxy elaphureLinkProxy play the role of communicating with the debug unit. It exports some API for connection management. Developers can use these API to build specific applications.

• Wpf elaphureLink.Wpf is a simple GUI wrapper of elaphureLinkProxy. It provides a number of utilities for managing drivers and connection control.

• Server Providers It may be the various devices containing the CMSIS-DAP implementation to provide debugging capabilities. For more examples, see Application case.

Server Providers Document

The most common development requirement is to build your own server provider. A server provider is often a DAP probe. Specific information can be found in the Server Providers Document.

Proxy Document

During each connection, a specific protocol needs to be followed between elaphureLinkProxy and debug unit. For more information about the protocol, see proxy_protocol.

You may want to build your own application using elaphureLinkProxy, in this case please refer to the Proxy API, available at Proxy API.
