Blinky Ensemble E8 Project

This Blinky project is a simple example that helps you checking basic tools and hardware setup.

Project Structure

The project is generated using the CMSIS-Toolbox and is defined in csolution format:

• M55_HE/M55_HE.cproject.yml defines the source files and the software components for the M55_HE core.

Hardware Setup

For initial development, use the PRG USB port to power the board and to have access to the Secure Enclave using the SETOOLS and a user UART.

J-Link

When using the J-Link debug adapter (connected to PRG USB), ensure that J-Link version 8.44 or higher is installed.

Note: Currently, the J-Link drivers do not support the E8 family. For support, copy the files from Alif's VS Code template to the JLinkDevices folder.

Building the project

In the CMSIS view, use the build button (hammer icon) to build the project.

Programming with SETOOLS

Go to the Alif Software & Tools page and download the appropriate SETOOLS V1.107.000 archive for your platform to a directory on your local machine.

To program the application on the DK-E8 board, run the Program with Security Toolkit (select COM port) VS Code task: go to Terminal - Run Task - Program with Security Toolkit (select COM port). Select the appropriate COM port. This needs to be done only once. Subsequent times, you can run the Program with Security Toolkit VSCode task instead.

Debugging

In the CMSIS view, use the debug button to start a debug session.

Operation

The M55 High Efficiency core toggles D4 and D6 RGB LEDs in a 500 ms interval (red/green/blue).

Note: For STDOUT (printf output) set switch SW4 to position U4 (UART4). Use VS Code's SERIAL MONITOR to see the printf debug output (set ot 115200 baud).
