Overview

The Alif Ensemble E8 Development Kit is a single-board development platform that can be configured to operate with the E4, E6, or E8 series devices in the Alif Ensemble family.

The Ensemble family of devices can contain up to two Cortex-M55 cores available as two separate CPU clusters.

RTSS-HP (High Performance): Cortex-M55 running at up to 400 MHz
RTSS-HE (High Efficiency): Cortex-M55 running at up to 160 MHz

Board Identifiers

The following board identifiers are supported:

Configuring a Console

Connect a USB cable from your PC to the USB-to-UART bridge connector, and use the serial terminal of your choice (minicom, putty, etc.) with the following settings:

Speed: 115200
Data: 8 bits
Parity: None
Stop bits: 1

The default UART consoles are:

RTSS-HP: UART4
RTSS-HE: UART2

Flashing

Alif Ensemble E8 Development Kit can be programmed using the Alif Security Toolkit (SETOOLS). Refer to the Ensemble E8 DevKit Product Page_ for detailed instructions on using SETOOLS to program the board.

Alternatively, the board can be flashed using a SEGGER J-Link debug probe with west flash. Connect the board to your host computer using the J-Link debug interface. The sample application :zephyr:code-sample:hello_world is used for this example.

Building and flashing for the High Performance core (RTSS-HP):

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: ensemble_e8_dk/ae822fa0e5597ls0/rtss_hp :goals: build flash

On the serial terminal, you should see the following message:

.. code-block:: console

Hello World! ensemble_e8_dk/ae822fa0e5597ls0/rtss_hp

Building and flashing for the High Efficiency core (RTSS-HE):

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: ensemble_e8_dk/ae822fa0e5597ls0/rtss_he :goals: build flash

On the serial terminal, you should see the following message:

.. code-block:: console

Hello World! ensemble_e8_dk/ae822fa0e5597ls0/rtss_he

Debugging

You can debug an application using west debug:

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: ensemble_e8_dk/ae822fa0e5597ls0/rtss_hp :maybe-skip-config: :goals: debug

This will start a GDB server and connect to the target.
