TWR-K21D50M tower module

Is there a way to re-program the TWR-K21D50M tower module with its initial demo firmware to get it back into its "out of the box" state?

I'm trying to diagnose why I can't see any "hello world" output via the OSJTAG interface (USB to serial bridge).

Hi Peter,

If you goto http://www.freescale.com/tower and then drill down to the Tower System Boards->Kinetis MCU Modules->TWR-K21D50M link.

The new web page has several methods to get the OOB (Out Of Box) code:

1) click on the Jump Start Your Design->Get started out of the box with TWR-K21D50M link. Then click on the TWR-K21D50M Sample Code.

2) click the Downloads tab, expand the Lab and Test Software (2) field to click on the TWR-K21D50M_SC_LAB code.

Both methods should download the same code (assumption...).

Once un-zipped you should be able to navigate to:

TWR-K21D50M Sample Code\TWR-K21D50M_SC\build\cw\TWR-K21D50M-OOBE

Regards,

David
