Constructing a Classroom IDE with Eclipse for ARM

Posted on by

For the next semester I will do things differently in my advanced embedded systems programming course (INTRO) at the University of Lucerne: Instead of using the Freescale provided CodeWarrior, we will use a DIY tool chain for ARM with Eclipse Kepler.

That way we we can offer students an open and convenient tool chain for their lab work, course assignments and own projects both at work and at home. So this post is about spending about 30 minutes to build your own tool chain which then can passed to students and coworkers so they have a complete toolchain installed in a few minutes.

With the Joystick shield I have a convenient way to drive and control a Zumo Robot without a wired connection:

While things started promising, there was a power supply problem at the end to be solved…

Enhanced RNet Wireless Components and Communication Stack

I’m using both the Freescale MC1320x and Nordic Semiconductor nRF24L01+ 2.4GHz in many projects. To make it even easier to use these transceivers in the RNet stack, I have updated it with several new functions.

GNU ARM Eclipse & Segger J-Link Device Name Settings

Thanks to the GNU ARM Eclipse plugins from Liviu it is easy to build and debug projects for all the different ARM cores. But I need to specify the device name in the debug configuration:

Device Name for Segger GDB Configuration

There must be an easier way for this? Yes, indeed, there is 🙂

Segger J-Link Firmware for OpenSDAv2

Posted on by

Segger just has released their OpenSDAv2 firmware. The OpenSDAv2 firmware is different from the OpenSDAv1 as it is using a different memory map and bootloader. The OpenSDAv2 e.g. is present on the new FRDM-K64F board. The availability of the Segger firmware is definitely good news for any owner of the FRDM-K64F board: so far only the CMSIS-DAP firmware was available (on top of the mbed bootloader). With this, it was not possible to use the board with CodeWarrior, except with using an external P&E Multilink or Segger J-Link. With that new Segger J-Link OpenSDAv2 firmware, I can now use the FRDM-K64F with any IDE which supports the Segger J-Link :-).

Binary (and S19) Files for the mbed Bootloader with Eclipse and GNU ARM Eclipse Plugins

Posted on by

The existing OpenSDAv1 (see “OpenSDA on the Freedom KL25Z Board“) bootloader is using the industry standard Motorola S-Record (S19) Files. However, new FRDM-K64F board (see “FTF: FRDM-K64F, Kinetis Design Studio and Kinetis SDK“) has OpenSDAv2 on it, which is an mbed bootloader. So how to create files with an IDE other than mbed for that bootloader which is present on the FRDM-K64F board by default? Well, creating binary files is one thing, but to have it working with the mbed bootloader is another challenge :-(.

Using the FRDM-K64F with CodeWarrior

The new flagship of FRDM boards is the FRDM-K64F board. After FTF I have explored different ways debugging the board, and received many comments and questions about it (thanks!). Freescale announced the supports with the new Eclipse based Kinetis Design Studio (KDS). But until KDS is out, how can I use the FRDM-K64F board with CodeWarrior?

Tutorial: User Interrupts with Processor Expert

I have been asked this question several times:

“How can I define my own interrupt vector with Processor Expert?”

So I think it deserves a short tutorial, if more than one person is asking this ;-).

There has been a lot of new Freescale releases recently around FTF, and I’m trying to catch up. For me as a Processor Expert Lover, it is good news that there is now the new version 10.4 available. And it comes in different ways:
