I/O with Host via OpenSDA

shauldorf — Thu, 02 Jul 2015 20:36:56 GMT

Hello all;

I’m newer to Kinetis and KDS.

I use KDS3.0 & KSDK1.2 with FRDM-K64F and FRDM-KL25Z.

This is my KDS Installation

I try to reproduce I/O demos based on two Erich Styger posts:

printf() and scanf() with GNU ARM Libraries, using ConsoleIO component.
Using a Terminal Input and Output; *without* printf() and scanf(), using Term component

The posts are old, Erich have used different tools chain.

Maybe not everything there is relevant, but they are excellent reference for beginners like me.

I’m looking for some reasonable explanation for:

FRDM-KL25Z

Project build:

Device page: processor to be used Board,
FRDM-KL25Z
Rapid Application Page: KSDK-none,
PE-selected

Generates following error:

FRDM-K64F

Project build:

Device page: processor to be used Board, FRDM-K64F
Rapid Application Page: KSDK-none, PE-selected

I ran into two problems without logical explanation

1. "ConsoleIO" - post

“printf/scanf” post I/O is working. The only unexplained obstacle is speed limit to 1200 baud.

If in “Component Inspector” for IO1:Serial_LDD:

Select folder “CPU clock/configuration selection”

Change the “Clock configuration 3” to disabled

There is no speed limit (tested in 115200 baud)

(String and Char) - post

SendStr method work but no response to ReadChar or ReadLine methods.

In both cases the UART pin configuration is the same.

But if during project build I use MK64FN1M0VLQ12 processor (instead FRDM-K64F board),

everything is working fine for the same configuration.

For the Project that is build:

Device page: processor to be used Board, FRDM-K64F
Rapid Application Page: KSDK and PE-selected
Using fsl_debug_console component

Every thing is working fine (strings, chars, put/get)

Hi Shaul,

the error message "Target processor is not selected" is a bug of the wizard if you select a non-SDK project with Processor Expert, and if you select a board (e.g. FRDM-KL25Z) instead of the microcontroller (KL25Z128M). This should have been fixed with an update, or simple create the project with the microcontroller on it selected, instead of the board name.

Hi Erich;

Thanks;

If you take a look on my “Installation details” you can see that there is “Processor Expert Patch 1”.

This patch doesn’t solve the wizard bug.

Yes I create the project with the microcontroller instead the board and it is working.

My question is if it is equivalent to board installation?

I thought that board installation is supporting all the board hardware and processor is supporting only the controller.

Hi Shaul,

yes, indeed, I have that patch installed too, but still have that issue. I thought it had been fixed, but it looks I was wrong about that.

The difference between the 'microcontroller' or the 'board' version: in the board version the pin muxing in the PinSettings component of the project is already set up to wire up the components of the board (e.g. LED, etc). So the pins already have the correct names. Apart of that, no difference.

Hello Erich;

Thanks, at least KL25Z I understand my problem. Let’s hope that Freescale will solve it
sometime before the merge with NXP.

Related to second part FRDM-K64F, I think it belongs to KSDK
forum or it doesn’t matter where it has posted.
