After setting my new 16” M1Max Macbook Pro, I found some surprising results for the kernel compile time. The Ubuntu Virtual Machine on my M1 MBP compiled the i.MX Linux kernel faster than an Intel i9 3650 Dell Precision workstation running native Ubuntu. Since the comparison is a bit like apple to oranges, I tried to minimize the variables, and, I also compared an older i7 Dell Precision M4700 and a Xeon.

PyeIQ is written on top of eIQ™ ML Software Development Environment and provides a set of Python classes allowing the user to run Machine Learning applications in a simplified and efficiently way without spending time on cross-compilations, deployments or reading extensive guides.

Now PyeIQ 3.0.x release is announced. This release is based on i.MX Linux BSP 5.4.70_2.3.0 & 5.4.70_2.3.2(8QM, 8M Plus) and can also work on i.MX Linux BSP 5.10.9_1.0.0 & 5.10.35_2.0.0 & 5.10.52_2.1.0. And also, in latest PyeIQ 3.1.0 release, BSP 5.10.72_2.2.0 is also added into supported list.

This article is a simple guide for users. For further questions, please post a comment on eIQ Community or just below this article.

This demo introduces the secondary boot of i.MX8QXP. 

This feature is very useful for such as OTA, rolling back. 

Some customer cases need hardware partition and the GPIO need to be allocated by bank.

It causes resource tensive. And some time, one GPIO bank assigned to the M4 side 32 bits of one bank are more than enough. And some customer cases need to use 1 or 2 bit to as board identification for the A core side. Because of the hardware partition, A core could not directly access the M4 partition resource.

The example is to change the i.MX8QXP MEK debug uart(lpuart0) to the base board(lpuart2).

The lpuart2 is J37 on base board.

uart2-linux-uart2_L5.4.70_2.3.0.diff, uart2-u-boot-method1_L5.4.70_2.3.0.diff and uart2-u-boot-method2_L5.4.70_2.3.0.diff are the patches. 

The NPU capability lies in the “sweet spot” for performance to enable real time response for common AI/ML problems. Combined with the video and vision co-processing capabilities, the i.MX 8M Plus will be the standard bearer for Edge ML/AI implementations

Switch i.MX8MM debug port is not simple like i.MX6. Just change the bootargs.The changes include atf(Key changes), u-boot, Linux and systemd.

We are pleased to announce that Config Tools for i.MX Application Processors v9 are now available.

We are pleased to announce that MCUXpresso Secure Provisioning Tool v2 is now available.

Have you recently been sceptical of using a contact-based access system in your office or a public place? This trait is a major concern in most places for a valid reason. An access surface in a public place is used by many individuals, which makes it a potential source for contracting the deadly Covid 19 virus. Taking this into account, iWave Systems, a leading embedded solutions provider, has successfully demonstrated an alternative solution using facial recognition technology. The solution helps customers with a zero-contact access application by using individuals' faces to authorize access to a commercial/industrial space, home/office, transportation, banking, and Government sites.

iWave Systems and Crank Software partnered up to support rich graphics on the powerful NXP i.MX 8 series system on modules and SBC boards. Powered by NXP i.MX8 application processors, the SOM and SBC are optimized for sophisticated real-time computing in embedded applications, and Crank Software’s UI development software, Storyboard, complements the high-performing modules with an out-of-the-box GUI experience.

The Debian based open-source Linux distribution Ubuntu finds its wide use across Desktop, Servers, Containers, and now in IoT and cloud applications. Being very secure and its OpenStack support, it is further getting adapted widely in high end embedded computing applications as well.

iWave systems rich i.MX8 System on Module and SBC product portfolio is supported with Yocto Linux, Android, and QNX BSP. Now iWave Systems is enabling the Bionic Beaver Ubuntu 18.04 LTS support to its latest i.MX8 Quad Max, Quad Plus, and i.MX8M, i.MX8M mini system on Modules and SBC products.

Wayland support in the BSP brings better performance, code maintainability, and security compare to X server. In Wayland, compositing is passive, which means the compositor receives pixel data directly from clients, and hence it reduces the latency compared to the X server. The GUI with the Wayland Compositor on the iWave i.MX8 board is shown below;

Hello everyone,

Greetings of the day...

      we are doing the flat design with imx6ul with 2 RAMs(MT41K512M8DA-107P). So how can i configure this in barebox source. is any reference is available with 2 RAMs?

Oftentimes, developing an end application is like a scary game of maze. One can easily get lost in its winding paths lined with unseen twists and obstacles. A wrong choice can lead you to start all over again, making the journey grim, and the goal out of reach.

For developers, the challenges are real and huge, turning the development process into a difficult chase to fulfill performance and time to market objectives while achieving customer expectations as well.

From prototype, integration to development, there are a multitude of bottlenecks lurking in every path. With so many design challenges to overcome, developers often find it hard to integrate cutting edge technologies in their end applications and optimize their designs with the best performance and features.

QNX is a Unix-like Real Time Operating System primarily developed for safety and mission critical embedded systems and includes the following unique features;
