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:
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:

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
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 :-).
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:
Kinetis SDK v2 with Processor Expert: Now many components can be used even with the Kinetis SDK v2.0 even with the Kinetis SDK not having Processor Expert included.
Updated Segger SystemViewer to v2.32a with post-mortem and static buffer support
Updated Segger RTT to v5.10u and fixed an issue with interrupts on Cortex-M4
