Thanks, I installed a new, separate instance and it looks like it will work for me.

Almost fully featured Keil MDK-ARM Lite with a main limitation of 32 kB of code (in ROM) can be downloaded for free from Keil website. However, I don't know if you will need a separate installation of Keil or it will be possible to unlock it in your Freescale enabled installation.

Anyway, you can see the full list of limitations here: www.keil.com/.../limits.asp

And since 2010, it is allowed to use MDK-Lite for commercial purposes: www.keil.com/.../3595.htm

The stack does not count in the 32kB limit as it is a completely separate and non-changeable part uploaded to a different part of memory. The programs themselves are not very space-consuming. Even one of the more complicated examples, which is ble_ant_app_hrm, consumes only 11kB of ROM. My most complicated project with Nordic chip so far was a design of some-kind-of proprietary smartwatches with a OLED display, accelerometer, 868 Mhz transceiver, GPS chip and two or three more peripherals. I didn't get over 20 kB of code. The Keil does a great job in optimizing the code.

Thus, for most projects, you are fine with Keil MDK-Lite.
