One of the major benefits of Processor Expert is that I can easily switch the device or processor used in a project. For example I can do my concept with a larger device with more FLASH and RAM, and then at the end easily switch to a smaller or even completely different device very quickly. For example I have a project working with the 64KByte FLASH version of the KE02Z (KE02Z68VLH2):

For a university research project I need a fast microcontroller with lots of RAM and FLASH memory. I have ordered a TWR-KV58F220M board from NXP which arrived yesterday. The special thing is that it has on of these new ARM Cortex-M7F on it:

The AMZ Formula Student Team did it again: they accomplished a new the world record today: accelerating with an electrical vehicle from 0 to 100 km/h in only 1.513 seconds!
A bootloader shall be small and concise. I very much like bootloaders which do not need a ‘special’ program on the host, so I prefer a simple terminal for this. While porting my serial bootloader to the NXP FRDM-K64F board, I have found RealTerm which offers a lot of cool features:

Sometimes it is very convenient to load a new firmware to a board without the need for a hardware debugger. This is usually done with a bootloader. The NXP Freedom and Tower evaluation boards have on-board debug device/microcontroller (OpenSDA) which can load different firmware implementations like CMSIS-DAP/mbed, P&E Multilink or a Segger J-Link OpenSDA applications. Both mbed and P&E implemenations support to program the board with drag&drop: simply send a file to a virtual MSD (Mass Storage Device) to get it programmed. The latest Segger OpenSDA firmware has this ability added now too: Programming the board with a virtual MSD device:

So this is my current week-end BBQ project: Pulled Pork out of the BBQ smoker :-). As a teaser, this is how the result looks like: tender, juicy slow-cooking smoked pork meat out of the smoker:

3.5″ Diskette Drives are not widely used any more: CDs, DVDs, memory/thumb drives and downloads from the web are the usual distribution method these days for software. Back a few years ago, software was distributed on one or many 3.5″ diskettes, and even before that time on 5 1/4″ floppy disk drives. So what to do with all these not-used-anymore hardware? Play music with it 🙂

My wife tells me that I have too many boards on my desk. That is only *partially* correct: there are many, but not *too* many. But I’m working on too many tasks, but that’s a different aspect :-). I’m using more and more the Kinetis SDK V2.0, and as a result of this I have multiple SDKs installed on my machine. Because with the SDK V2.0 I get a download for each device/board installed (see “First NXP Kinetis SDK Release: SDK V2.0 with Online On-Demand Package Builder“). So my list of SDK folders is growing, as shown with the ‘New SDK 2.x’ wizard in Kinetis Design Studio:
Multiple Kinetis SDKs
The same time, the amount of free disk space is reducing. What if I could combine all these SDK’s?
Sometimes it is all about knowing the simple tricks in Eclipse which make life easier. Like this one: how to have a split editor view so I can edit multiple different sections of a source file:
