Seeed Studio Arch Mix NXP i.MX RT1052 Board

The Seeed Studio ‘Arch Mix’ board is a small and versatile development board with an NXP i.MX RT1052 on it, and it costs only $29.90. So I was not able to resist and just have ordered one so I can explore it.

Visualizing Global Variables while Target is Running with Eclipse and MCUXpresso IDE

By default, Eclipse provides ‘stop-mode-debugging’: in order to inspect the target code and data, I have to stop the target. But with the right extensions as present in the Eclipse based MCUXpresso IDE, it is possible to inspect the target even while it is running.

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:

LPC4322JET100 on LPC55S69-EVK

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.

Tutorial: Using external Debug Probes with NXP LPC845-BRK Board

One great thing with that new NXP LPC845-BRK board is that it is possible to use it with any standard SWD/JTAG debugger, as it has the 10pin debug header present on the board. It is not populated by default, because the LPC845-BRK includes a CMSIS-DAP debug probe already. But if I want to use a SEGGER J-Link, a P&E Multilink or the NXP LPCLink2, this is certainly something to consider:

First Steps with the NXP i.MX RT1064-EVK Board

I always reserve time between Christmas and New Year to get my hands on technology pieces which I might not have any time otherwise. Among different things I ordered the NXP i.MX RT1064-EVK board from Mouser.com, and it arrived right before Christmas. Time to have it unboxed and started….

Tutorial: First Steps with Embedded Artists NXP i.MX RT1052 OEM Module

Not ready for the complexity of a full blown Embedded Linux, but need that extra compute performance? Need an ARM Cortex-M7 running at 600 MHz module on a half-sized business card, ready to be integrated? Here we go: the Embedded Artists i.MX RT1052 OEM module:

Embedded Artists NXP i.MX RT1052 OEM Module

Embedded Artists NXP i.MX RT1052 OEM Module

Compute modules are very common in the Embedded Linux space, for example see this Toradex module. The reason is simple: these high-performance boards simplify the design, as I don’t have to care about the BGA packages and the external SDRAM and FLASH devices: everything is on a module I can easily integrate into my base board.

MCUXpresso IDE 10.2.1

NXP has just released the 10.2.1 update of their flagship Eclipse based IDE. While the number increase from 10.2.0 to 10.2.1 indicates a minor release, there are a several things which make me move over to that new release.

Adding a Rocktech Capacitive Touch LCD to the NXP i.MX RT1052 EVK

It is never too early to start thinking about Halloween projects :-).

When I ordered originally the MIMXRT1050-EVK from Mouser, it was without the LCD display (see “MCUXpresso IDE V10.1.0 with i.MX RT1052 Crossover Processor“. I ordered the LCD for the board soon after writing that article, but I was too busy with the university lectures and exams to get a hand on it. Finally I have spent a few hours at night and I proudly can say: the display is working 🙂

Debugging the Teensy 3.6 with Eclipse MCUXpresso IDE and CMSIS-DAP LPC-Link2

The Teensy boards are great, but as they are they are not really useful for real development, as they lack proper SWD debugging. In “Modifying the Teensy 3.5 and 3.6 for ARM SWD Debugging” I have found a way to get SWD debugging working, at that time with Kinetis Design Studio and the Segger J-Link. This article is about how debug the Teensy with free MCUXpresso IDE and the $20 NXP LPC-Link2 debug probe:

Custom 3D Printed Enclosure for NXP LPC-Link2 Debug Probes

I love 3D printing as it enables me to create custom enclosures for all kind of projects. The NXP LPC-Link2 probe is great, but it lacks a protective enclosure. So I decided to create a custom enclosure. And as 3D filaments are available in different colors, I experimented with red and black and custom painting:

MCUXpresso IDE: Blinky the NXP LPC800-DIP Board

During Embedded World 2017 in Nürnberg I was lucky to get a handful LPC800-DIP boards. To get all students who were lucky to get one, here is a tutorial to make that very exciting ‘blinky’ application on that board:

MCUXpresso IDE: Terminate and Disconnect a Debug Session

Eclipse for C/C++ (CDT) offers two different ways to get out of a debug session: Terminate and Disconnect:

The terminate and disconnect behaviour is not standardized, and varies between Eclipse distributions and debug connection. This article is about how things are handled in MCUXpresso IDE, and how I can influence the behaviour.

Using Eclipse to Program Binary Files to an Embedded Target

I’m using Eclipse based IDE’s to develop and debug my embedded applications. This works great, as Eclipse has all the necessary tools to edit, build and debug it. But when it comes just to download/flash a binary to the board, then things are pretty much specific to the tools used. With the advent of the new MCUXpresso IDE, here is how that Eclipse IDE can be used for this.

Using the LPCXpresso V2/V3 Boards to Debug an external Board

The MCUXpresso IDE (see “MCUXpresso IDE: Unified Eclipse IDE for NXPs ARM Cortex-M Microcontrollers“) has one great feature: it includes debug support for the popular LPC-Link2 debug probes. That way I have yet another powerful debug probe with extra features for ARM based boards. That LPC-Link2 circuit is present on many LPCXpresso boards from NXP. So why not using it to debug it my custom hardware?
