Mother of Components: Processor Expert with NXP Kinetis SDK V2.0 Projects

Posted on by

Unfortunately, now the NXP Kinetis SDK V2.0 does not include Processor Expert support (see “First NXP Kinetis SDK Release: SDK V2.0 with Online On-Demand Package Builder“). But at the Lucerne University we are using more than 150 different custom Processor Expert components we would like to use with that new SDK. So how to make them working with the Kinetis SDK V2.0? Using a Processor Expert as “the mother of all components”:

Processor Expert Component Repositories

Processor Expert for Kinetis v3.0.0 (which is part of Freescale Kinetis Design Studio v3.0.0, KDS) has now the concept of ‘repositories’ for the components.

Previously, Processor Expert was able to use two paths for its components (e.g. in KDS v2.0.0):

  1. The ‘System‘ directory inside the Eclipse installation
  2. The ‘User‘ directory: a fixed path, global for all installations

These directories are listed in the workspace settings (menu Window > Preferences > Processor Expert > Paths):

USB CDC with the FRDM-K64F, finally!

Posted on by

Sometimes I think that a problem should be solvable in a few minutes, and then it turns out that it lingers around for months. Very, very frustrating! Such a thing is getting the USB 4.1.1 stack running on the FRDM-K64F board. I have that board since April 2014, and it took me 7 months to get the FSL USB stack running on it :-(.

McuOnEclipse Releases on SourceForge

When I started the McuOnEclipse project back in 2012, I did not expect that it would create that much of attention :-). So far I’m sharing the project files on GitHub (see “McuOnEclipse goes Git“). GitHub is excellent for sharing sources, but not a good way to share release (binary) files. It is somewhat ok for small/few files, and initially that worked well for the few Processor Expert files (see “Processor Expert Component *.PEupd Files on GitHub“). However, with the amount of components and binary releases, the GitHub repository gets bloated. So I’m performing some maintenance work, and so I’m moving binary releases to a new McuOnEclipse SourceForge site.
