While Arm continue to supply older (Armv7-A based) Fixed Virtual Platforms, the Arm Platforms deliverables no longer provide updated sources, binary artefacts, or instructions for them.
Most of these platforms will actually work with a more recent release…
Hi all,
We have created a new forum for any questions or comments regarding virtual platforms based on Arm Fast Models or Arm Cycle Models, including Fixed Virtual Platforms.

I am using ARM DS5 v5.20. I could not understand how to profile my code using FVP. My expectation is to profile it completely in my local PC without any HW i.e., to see list of functions and the amount of CPU consumed by those functions. To my understanding…
Hi,
I am trying to profile Mali GPU counters on Odroid XU3 using Streamline. I have downloaded DS-5 Ultimate Edition trial for this purpose and built and run the gator daemon on the board ( using the steps from https://github.com/ARM-software/gator )
1…
Hi,
I've installed Ds5 development tools with streamline, I use gator to grab execution informations and I loaded vmlinux file in order to display kernel function call path. Streamline is a very powerfull tool but I'm wondering that I can't filter…
Why should we call secure function in handler mode? What is the design purpose for this? As we know, none-secure side can also call secure function in thread mode.
The Iris Debug and Trace interface represents a major step forward in functionality for virtual prototypes incorporating Arm Fast Model. Iris complements and will, in time, replace the existing debug (CADI – Component Architecture Debug Interface) and…
Accurate and efficient tests are essential when developing software for embedded systems, particularly in continuous integration and functional safety flows. Quick pass/fail results from a comprehensive regression test suite enable teams to develop quality…
Developing software involving DSP, control systems, and complex algorithms running on embedded targets is a humbling task. To streamline this often complex and tedious process, Arm has several offerings to help verify & optimize code under development…
There are a few common questions that we get from customers when talking about virtual prototypes for software development which we will address in this blog.
Virtual prototypes (VPs) help developers…
The Scale Vector Extension (SVE) is an optional extension to the Armv8-A architecture. A scalable vector length enables multiple processor performance and cost points. Prior to silicon availability, one way to learn SVE is to use the Arm HPC Compiler

To develop, port and debug the Linux kernel on a platform, you will need to be able to set breakpoints, view registers, view memory, single-step at source level and so on - all the normal facilities provided by a debugger. You may also need to do these…
In a previous blog I wrote about the Fastline plugin developed for Arm Fast Models, and how it can be used with the Streamline performance analyzer. With the recent release of DS-5 5.28, we have enhanced this experience, including all necessary files…
Hi,
I'm starting to explore this technology by running the TrustZone example application in Linux using GNU ARM Toolchain. This example is provided by a CMSIS software pack containing this example called "TrustZone for ARMv8-M No RTOS" which I was…
If you have ever experienced the London Underground rail system you will no doubt have heard the voice intoning the phrase “mind the gap” at many stations. Every time I hear that, I feel like shouting “fix the gap”! When I joined…
Hello,
I would be interested to try the new features of the ARMv8-M architecture, in particular v8-M TrustZone, but I can't find necessary tools in order to do so.
1. I need a toolchain that supports the new instructions introduced with v8-M (SG, BXNS…
