After the ‘blue‘ series, here is yet another hicking flower color collection: Lilac!

Blue Gentian

After the ‘green‘ one, here is another impression from my recent hiking tours in the Alps: this time a combination of brown, green and blue.
The one below is the Gentiana Verna (or Spring Gentian). It is rather small and widespread, found on sunny alpine meadows.

Composition of Green with Algae

Impression from one of my recent mountain hiking tours: Mountain spring water flowing slowly through grass meadows, building a symbiosis with green algae. Maybe a camera cannot reflect the number of green colors the human eye is able to see?

Happy Greening 🙂
SWO with NXP i.MX RT1064-EVK Board
With the cost of an single pin, many ARM Cortex-M boards including the NXP i.MX RT1064 can produde SWO data: think about a pin able to stream data out of the chip in realtime. For example interrupt activity which otherwise might be hard to capture:

Steampunk Lasercut Enclosure for Raspberry Pi
Having access to a laser cutter makes it possible to design custom enclosures. This one is for a Raspberry Pi in a Steampunk design:

Reverse Engineering of a Not-so-Secure IoT Device
The ‘Internet of Things’ is coming! It started as an overused marketing hype with no real use case (who needs internet connected fridges? Who wants the internet connected toilet paper?).
New ‘things’ start to pop up, useful or not: From smart bulbs (Philips Hue), thermostats (Nest), smart TV (Samsung and others) up to voice assistants (Alexa, Cortana, Google). You might even have installed one of these, right? What about temperature and humidity sensors? Probably there is nothing wrong with that?
But what would you think if one morning you find a strange unknown device installed under your working desk, connected to the cloud and internet?
MCUXpresso Eclipse IDE Mouse Tips & Tricks
In a modern development workflow both command-line and a graphical user interface has its place. On the GUI side, Eclipse is famous that it offers many different ways to accomplish something which is great. But sometimes I continue to use an old habit or way because I have missed that there is a newer and better way, and the MCUXpresso Eclipse IDE is no exception to that. In this article I show a few ways how to use the mouse even more productive.

Weissdorn/Hawthorn (Crataegus monogyna)

I like the Crataegus or ‘Hawthorn’. The small white flowers of the white variant are not really spectacular alone, but together they build a beautiful ensemble:

The Hawthorn provides food and shelter for many birds. And according to legends, they are associated with fairies.
Happy Flowering 🙂
Tutorial: MCUXpresso SDK with Linux, Part 3: RAM and XiP Code on i.MX RT1064
In my previous articles I have used the command line on Linux to build and debug NXP MCUXpresso SDK applications. In this article I’m running code on NXP i.MX RT1064 in RAM or FLASH.

Internal and External Debug Options for the NXP LPC55S69-EVK Board
The LPC55S69-EVK board comes on-board debug probe. The board includes the LPC4322JET100 device which acts like NXP LPC-Link2 debug probe:

But it is easily possible to use the board with an external debug probe or re-program the onboard one as a SEGGER J-Link debug probe.
