using CDC with usb stack v4.0.2 on FRDM board

[steve_fae]

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?

Hi everybody, I did this example and It worked very well on Freedom Board (tested in Win7 and WinXP). Then I did the same on a board with Kinetis K60 and I faced a problem. The example in this new board worked fine in WinXP but in Win7 the driver is not recognized. Do you have some tip?

Thanks!

Hi Diego,

did it not enumerate properly? Which .inf file did you use? I know that there might be some issues with incompatible .inf files. I have attached mine which works fine with XP, Win7 and Win8.

I hope this helps.

[diego_augustus]

Thank you for your attention Erich.

Yes, I didn't enumerate properly only in Win7. I tried your .inf file without success.

Now, I tried the same example in a Tower Module with Kinetis K60 (TWR-K60D100M and TWR-SER) and it worked well (at Win7 and WinXP).

Probably the problem is with my board. The difference between my board and the tower is the Kinetis package, but the weird thing is working at WinXP and not at Win7.

I will keeping trying.

I found the problem with the help of Freescale Support.

I missed a capacitor in the VOUT33 signal.@

"This capacitor is a requirement and its typical value is 2.2uF. When this capacitor is missing or its value is out of spec, sometimes the USB applications do not work and work in a different PCs. Becuase this cap is used to filter the D+ and D- signals."

Steven,

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

Luis

Hey Luis, so I tried 4.0.3 and still get compile issues after importing project

[LuisCasado]

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

[steve_fae]

I imported your project and did a clean and build.  same problem.

[LuisCasado]

Hi,

Did you import the PE package from 4.0.3?

Best Regards,

Luis

[steve_fae]

I just imported the .project into CW.  nothing else.

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

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

[LuisCasado]

Hi Jim,

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

Best Regards,

Luis

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.

[BlackNight]

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

[JimDon]

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.

[steve_fae]

Also, it seems that this demo has a bug as well.

In PE_LDD.h, in front of the line 967 “typedef struct LDD_USB_Device_TTD_Head_Struct“ add “#pragma pack(1) “ and after the line “} LDD_USB_Device_TTD_Head; “ add “#pragma pack()“. I’ll attach a screenshot too. Make sure that, in project properties, under Processor Expert tab, set “Generate code before build automatically” to No. Make sure that after any regeneration of the project you add the lines stated above.

[JimDon]

Steven,

When you say demo, do you mean the one in the 4.0.3 package, or the one Luis posted?

Really??? You have to change it after each regen???

That is not good.... that file must be some where.

Erich, could you permanently fix this by changing the file that is copied?

Wow, have no idea how I posted my contact info.  Anyways, with the changes Freescale recommended my colleague got the FRDM board to enumerate correctly with both the OpenSDA connection and the KL25 connection being CDC.  I still can't get the KL25 CDC to enumerate correctly.
