MCUXpresso IDE V10.1.0 with i.MX RT1052 Crossover Processor

In “Eclipse MCUXpresso IDE 10.1 with integrated MCUXpresso Configuration Tools” I mentioned that I wanted to try the i.MX RT1050 processor. Well, finally my ordered board from Mouser arrived, right on time for the week-end, so I had a chance to use that ARM Cortex-M7 running at 600 MHz :-).

Eclipse MCUXpresso IDE 10.1 with integrated MCUXpresso Configuration Tools

Back in March 2017, NXP had rolled the MCUXpresso IDE starting with Version 10.0.0. With the intent to unify the SDK, LPCXpresso, CodeWarrior, Kinetis Design Studio and Processor Expert into one unified and integrated set of tools. V10.0.0 was a good start. The MCUXpresso IDE V10.0.2 in July was more of a smaller update, and the Pin and Clock configuration tools were not integrated, no added tool for peripheral configuration.

A week ago the MCUXpresso V10.1.0 has been released which shows where the journey is going: an free-of-charge and code size unlimited Eclipse based integrated set of tools to configure, build and debug Cortex-M (Kinetis, LPC and i.MX RT) microcontroller/processor based applications.

I have used it for a week, and although many things are still new, I thought I’m able to give an overview about what is new.

Compiler Explorer

If you are like me – someone who always wants to know what the compiler generates for a piece of source code – then have a look at the Compiler Explorer: A web-based compiler code comparison tool:

Compiler Comparison

Thanks to Matt Godbolt, I can select different compilers and compare their output for a given source code. Very useful to see the impact of a compiler optimization or to compare different GCC compiler versions.

Happy Comparing 🙂

First Steps with the Variscite DART-6UL i.MX6 UltraLite Development Kit

For a next-gen course I’m evaluating different platforms, and one of it are modules based on the NXP i.MX ARM architectures. In this article I have a look a the Variscite DART-6UL development kit which includes the NXP i.MX6Ultralite ARM Cortex-A7 plus a 7″ capacitive touch LCD:

eSOMiMX6-micro: NXP i.MX6 System on Module

An interesting trend in the industry are SOM (System on Module): a high performance processor typically running Linux, Windows or Android with all the memory and necessary power logic gets put on a small module. The key benefit is that I don’t need to worry about the complex ball grid routing and the DDR memory connections/lines: all these problems are solved on a small module which then I can use in my design. It seems that NXP i.MX application processors are getting popular in this domain, and after looking at the Toradex Colibri modules, I have an i.MX6 module on my desk from e-con Systems:

Tutorial: Building FreeRTOS Applications for ARM Cortex-M4 on i.MX7 with Eclipse

Command line tools to build applications are great. But productivity goes up if I can use the standard Eclipse environment with GNU tools. This tutorial is about how to use standard and free GNU and Eclipse tools to build my FreeRTOS application for the ARM Cortex-M4 on i.MX7 🙂 :

Tutorial: Updating Embedded Linux on Toradex i.MX7 Colibri Module using SD Card

My Toradex i.MX7Dual module comes with a preflashed Linux distribution (see “Tutorial: First Steps with NXP i.MX7 and Toradex Colibri Board“). As with any other things, Linux gets updated from time to time, and Toradex publishes new firmware. In this article I’m documenting how I can update Linux in the external FLASH on that module.
