MCU initialization for K20 series

evgenik — Wed, 22 Feb 2012 18:15:29 GMT

Hi.

I worked with CW 10.2 IDE. I received from Freescale example boards for K20 but Processor Expert haven't initialization package for K20 MCU. Where I can download update for Processor Expert or Code example for K20 MCU series initialization?

Thanks.

Hello,

are you using the final 10.2 (or the beta?).

At least my final 10.2 shows Processor Expert support for K20D and K20F.

I correct my question.

We are develop project with Freescale K20 MCU with 64 and 32 pins, but in CW 10.2 Processor Expert haven’t these configurations. Are you have any updates for CW 10.2 or MCU initialization examples for these packages?

Evgeni.

Hello,

hmm, I see now your point. I have the PK20X128VLH (64pin) on the TWR-K20D50M board.

But Processor Expert only shows the MX20DX128ZVLQ10 package :smileysad:.

Hello,

I have verified it in the CW V10.2 final version and I have not encountered a problem with selection of K20 MCU in 64 and 32 pin packages.

It seems that the problem was originally caused by providing incomplete ID of the selected MCU. TWR-K20D50M means that the user has 50 MHz variant of the MCU, so the user must select a MCU from the "K20D (50 MHz) Family" group.

After correct MCU selection in project wizard, the requested pin variant will be available, for details please see the attached screen-shots.
