By default I’m programming the Elf/Dwarf (.elf) file present in the GNU ARM Eclipse debug configuration:
Elf File to be Downloaded
But how to program the board with something different from the .elf file?
With Processor Expert projects it is very easy to change the heap and stack size: There is a setting for this in the Cpu component settings, under the ‘Build options’ tab:
Heap and Stack Size with Processor Expert
As there is no Processor Expert in the NXP Kinetis SDK V2.0 (see “First NXP Kinetis SDK Release: SDK V2.0 with Online On-Demand Package Builder“), how to do the same in a SDK V2.0 project?
The bad thing with Eclipse and GDB is: if something is failing, then all what I get is a very cryptic error message when I launch the debugger:
The system tried to join a drive to a directory on a joined drive
In “Debug Multiple Boards with GDB at the Same Time” I have used the Segger J-Link to debug multiple boards, from the same IDE, at the same time. The remaining question in that article was: how to do the same the P&E Multilink/OpenSDA?

The world is changing, and the say is “change is good” :-). In the software and API world, change very often means that a change results into something broken. So I had battled with semihosting working on the NXP Kinetis parts, only to find out that it does not work any more with using the latest version 2.0. The semihosting output e.g. with P&E debug connection remains empty:
No Semihosting output
So how to fix this?
Related to my earlier article about using OpenOCD, I want to share something I have learned (again) with OpenOCD v0.10.0:
I was running often into the following error:
Warn : Cannot communicate... target not halted. Error: auto_probe failed Error: Connect failed. Consider setting up a gdb-attach event for the target to prepare target for GDB connect, or use 'gdb_memory_map disable'. Error: attempted 'gdb' connection rejected
OpenOCD cannot communicate
FreeRTOS is probably the number one RTOS used, and Eclipse is likely the most popular IDE I can think of. But debugging FreeRTOS applications with Eclipse and GDB is somewhat limited? What I would like to get at the minimum is this: ability to see all the different threads in the Eclipse debug view like this:
FreeRTOS Threads in Eclipse with OpenOCD
As you might guess from that screenshot: this post is about how to make FreeRTOS tread debugging possible with Eclipse and GDB :-).
These days, everyone is using USB memory sticks to transfer data from one machine to another. Or we are using CDs or DVD’s to install software. Well, sometimes at least.
Still remember the ‘old’ days where 3.5″ Diskettes were commonly used? Seems like these days are gone. So what to do with that hardware? Play music!

It has been already two months after the Feb 2016 release, and so much things are going on, so a new release was overdue. Today I have released a new version of the McuOnEclipse components on SourceForge with the following main changes and features:
See readme on SourceForge for the full history.

The Primula is a flowers in my region which announces the spring time. Captured that beautiful one today with a bug on it 🙂
