using CDC with usb stack v4.0.2 on FRDM board

steve_fae — Mon, 18 Feb 2013 19:56:16 GMT

I imported USB_CDC_DEVICE_MKL25Z128_PEx into CW 10.3 and when I try to build the project I get a lot of path error issues. What is the best way to fix this?

Steven,

Just tested the same project in 4.0.3 version and works fine. Please download and try that version.

Regards,

Luis

Hi,

I don't remember if I had that issue. Please, backup your proyect and unzip the attached. I assume you have imported the PE Device stack into CW10.3.

Best Regards,

Luis

Hi,

Did you import the PE package from 4.0.3?

Steven,

You missed to read the "Freescale Processor Expert USB Components Quick Start Guide" doc.

Processor Expert -> Import Package - > Select C:\Freescale\Freescale USB Stack v4.0.3\ProcessorExpert\Components\USB_DEVICE_STACK.PEupd -> Open

Rebuild the project

Getting closer, I imported usb device stack but now missing some include files such as usb_cdc.h and usb_framework.h

I added usb_cdc.h and now it can't find descriptor.h

As you imported first the project without the PE component. I would close the project and remove from workspace. Restart CW and import again, even in a new workspace. It should work without any modification

did you mean to say import usb_cdc_class instead of usb_device_stack? thanks for your help btw

Re: using CDC with usb stack v4.0.2 on FRDM board

LuisCasado — Tue, 19 Feb 2013 02:07:02 GMT

No, I mean the CW project. You only need the device stack PE component and you already have imported it. Try to remove the project from workspace or just switch to different workspace and import again the application project

Luis, have a nice cold one on me. I created a new workspace, re-imported the project and it compiles with only 27 warnings! hehe

Goal is to help customer so that when they attach a PC to their product through USB it tells them a value over CDC. Now I need to figure out how to implement this project in their working KL25 project. Thanks again.

steve_fae — Tue, 19 Feb 2013 02:42:27 GMT

ok, now running project on FRDM board using Open SDA interface. As you can see from my Device Manager

Open SDA enumerates to CDC on com2 but the other usb connection that connects directly to the KL25 doesn't enumerate properly. Any ideas how to get it to enumerate to CDC? Is the OpenSDA connection going to be a problem?

In case anyone else wants to read this:

USBPEXQSG.pdf = USB Processor Expert Components Quick Start Guide

It is include in the 4.0.3 package here:

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MEDICALUSB

A question. The document says:

"On Component Wizard, chose File-> Import-> Import components form package… as the

following figure."

I can't find any "Component Wizard" in 10.3 ? What do mean by "On Component Wizard" ?

What "form" am I supposed to use? Do I fill out a form? I

Hi Jim,

Component wizard allows you to create custom PE components. Now is integrated in CW10.3

Luis,

Except you must have a special license to use that, so I do no think that is the correct answer.

I get "A Valid Component Development Environment License was not found". when I try that.

Freescale has released a free Community license for the CDE (Component Development Environment), see this wiki.

The USB stack was tested with previous versions of CW10.3. Please try this:

Add #pragma pack() at the end of the file usb_devapi.h in /Generated_Code folder, after final #endif

Rebuild without generate the PE code.

Thanks for the tip Erich. I could use that!

However the correct answer is:

Use Processor Expert/Import Package browse to the PEupd file and import it.

The document "Freescale Processor Expert USB Components Quick Start Guide" is out of date and misleading.
