The Alif Semiconductor Ensemble (E8/E7/E6/E5/E4/E3/E1) MCUs create a scalable and compatible continuum of highly integrated embedded processor devices for use in low-end to high-end intelligent IoT end-point applications. Architected for power efficiency and long battery life, these devices deliver high computation and ML/AI capability, multi-layered security, computer vision, and highly interactive human-machine interface.

Flash Banks

Flash Bank Base address J-Link Support Loader
Name Size
Internal flash 0x80000000 YES.png Default Up to 5.75 MB
OSPI 0xC0000000 YES.png Default Up to 256 MB


Note:
  • OSPI flash programming is supported for octa flashes IS25WX128M/IS25WX256M/IS25WX512M/IS25WX01G/IS25WX02G only

Watchdog Handling

  • The watchdog is fed during flash programming.

Multi-Core Support

Before proceeding with this article, please check out the generic article regarding Multi-Core debugging here.
The AlifSemi Ensemble family comes with a variety of multi-core options.
Some devices from this family feature a secondary core which is disabled after reset / by default.
Some of the are available with enabled lockstep mode, only.
In below, the debug related multi-core behavior of the J-Link is described for each core:

The J-Link support for the Ensemble devices includes both Cortex-M55 cores, and both Cortex-A32 cores. The user can configure the accessibility of the cores with the Alif Security Toolkit.

Example Application

The following example project was created with the SEGGER Embedded Studio project wizard and runs out-of-the-box on the Hilscher NetX90 evalboard. It is a simple Hello World sample linked into the internal flash. SETUP

Tracing on Alif Semi Ensemble E7

This section describes how to get started with trace on the Alif Semi Ensemble E7 MCUs. This section assumes that there is already a basic knowledge about trace in general (what is trace, what different implementations of trace are there, etc.). If this is not the case, we recommend to read Trace chapter in the J-Link User Manual (UM08001).

Note:

Some of the examples are shipped with a compiled .JLinkScriptfile (extension .pex), should you need the original source, please get in touch with SEGGER directly via our support system: https://www.segger.com/ticket/.

To create your own .JLinkScriptfile you can use the following guide as reference: How_to_configure_JLinkScript_files_to_enable_tracing

Minimum requirements

In order to use trace on the Alif Semi Ensemble E7 MCU devices, the following minimum requirements have to be met:

  • J-Link software version V8.88 or later
  • Ozone V3.40d or later (if streaming trace and / or the sample project from below shall be used)
  • J-Trace PRO version V3.0 or later for streaming trace

To rebuild the project our IDE Embedded Studio can be used. The recommended version to rebuild the projects is V8.24. But the examples are all prebuild and work out-of-the box with Ozone, so rebuilding is not necessary.
