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 🙂 :
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.
In my previous article (see “Tutorial: First Steps with NXP i.MX7 and Toradex Colibri Board“) I have booted the i.MX7 on a Toradex CPU module. In this post I’m showing how to run a FreeRTOS application on that board.
I’m using in several projects different variants of Raspberry Pi boards: they are great and providing a lot of processing power. However, they are not suitable for any hard realtime systems. For a different class of projects I’m currently evaluating the NXP i.MX7 processors: the cool thing with these is that they have up to two ARM Cortex-A7 running at 1 GHz, plus a Cortex-M4 running at 200 MHz. And here things get really interesting: I can run a realtime application and FreeRTOS on that M4, while running Linux on the A7 :-).
