Many tool chains and linker are able to produce S19 files, such as with the GNU tools it is the ‘objcopy‘ which does this job (see “Binary (and S19) Files for the mbed Bootloader with Eclipse and GNU ARM Eclipse Plugins“). But these tools usually cannot handle the special cases. For example on the Freescale Kinetis K64F my serial bootloader (see “Serial Bootloader for the Freedom Board with Processor Expert“) had a problem with these lines in the S19 file:
Not aligned S19 file entries
In “How to Add Register Details View in Eclipse” I showed how to add the Register detail support in Eclipse using the EmbSysRegView plugin. This was for Luna/Mars, and for the version v0.2.4 of the plugins.
Since then, there is a new version of Eclipse (MARS, see “Going to Mars: Building a DIY Eclipse IDE for ARM Embedded Microcontrollers“) and the EmbSysRegView plugin has been updated to v2.0.5. Makes everything much simple, so here is an updated post with the details how to add register detail view to Eclipse Mars.

Given all the posts I already have published on a similar topic, this one will be a short one: how to use the Freescale FRDM-K64F board with OpenSDAv2 to debug another board:

In “Going to Mars: Building a DIY Eclipse IDE for ARM Embedded Microcontrollers” I described how to install an Eclipse based IDE for ARM, based on Eclipse Mars (4.5) and CTD (8.7). There are many great new features in Eclipse Mars which makes that switch worthwhile: the Launchbar:

A dream is are now a reality: a really, really easy way to build, run/debug an application!
It has been a while since I published my ‘build my own DIY IDE’ (see “DIY Free Toolchain for Kinetis: Part 1 – GNU ARM Build Tools“). I have used that approaches in my classes successfully. Now a new semester is coming up, so time to update the instructions using the latest Eclipse IDE (Mars) and tools (GCC ARM Embedded (launchpad) with GNU ARM Eclipse).

Some might say that Eclipse is too powerful and has too many features. But to me, the many small and somehow hidden gems can make a big difference in my daily life. One of these features is ‘Step Into Selection’ while debugging.
Very often I have a source line with nested function calls like this:

In “CodeWarrior Flash Programming from a DOS Shell” I showed how to program a device from the DOS shell. Because that example was for ColdFire and CodeWarrior for MCU10.2, here is the same for a Kinetis (FRDM-KL25Z) and CodeWarrior for MCU10.6. In my workspace (c:\tmp\wsp_10.6) I have a project folder (FRDM-KL25Z).
I’m using the ‘Flash Programmer’ to sneak the needed commands:

Segger releases often new application and firmware updates. If I install an IDE like the Freescale Kinetis Design Studio, it comes with that firmware version available at that time. How to take advantage of a new Segger release?

I need to program several boards with a firmware: a number too small for serious batch/factory programming, but a number too high doing this with the debugger. I want this:
Need to program a few boards…
The STMicroelectronics STM32F103 (ARM Cortex-M3) Nucleo boards include the on-board ST-Link v2 circuit which allows to debug the board. This circuit is similar to the OpenSDA circuit found on Freescale boards. Unlike the Freescale OpenSDA, the ST-Link is only the ST-Link: it is not possible to load a P&E Multilink or Segger J-Link or firmware on it. Luckily, the ST-Link has a SWD connector, but this connector is a non-standard one. So how can I debug that board with an Eclipse based environment with GNU ARM Eclipse plugins and a Segger J-Link?
