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:
The NXP LPC845-BRK board is a tiny an inexpensive (sub $6) breakout board. The board includes a CMSIS-DAP (LPC11U35) on-board debug probe which can be used as a debug probe to debug any NXP LPC, Kinetis or i.MX RT device 🙂
It is a common thing to boot a Linux system (see the Raspberry Pi) from a micro SD card. It is not that common for a microcontroller. The NXP i.MX RT ARM Cortex-M7 fills that gap between these two worlds. No surprise that it features a ROM bootloader which can boot from a micro SD card.
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….
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.
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 🙂
