MSC & CDC Descriptor file conflict

Hello everybody,

i'd need some help with a the USB Interface of the MSP430F6636

Goal is to achieve a MSC + CDC.

After reading the Programmer's guide, successfully tryied both MSC SD Card & Simple CDC LED example on my custom board.

i just tried to merge both applications, using the descriptor tool as help

SO here is what I've done.

Created a new project

- Copied USB_API Folder from the devpack

- Copied CDC's USB_Config folder, deleted the files inside, replaced with the descriptor's output

- Copied the CDC's USB_App folder

- Added FatFs folder, msc.c & .h into the USB_App folder

- Copied CDC's hal.c & .h main.c & system_pre_init.c into the project

- Added these Include lines from the MSC example into the main.

#include "USB_API/USB_MSC_API/UsbMscScsi.h"
#include "USB_API/USB_MSC_API/UsbMsc.h"
#include "USB_API/USB_MSC_API/UsbMscStateMachine.h"
#include "USB_app/msc.h" // FatFs #includes

Now when i build the project, i become these errors (see Pic)

If needed I'll upload the complete list.

I think all starts here #145 ....

Any ideas ?

Regards

First start to solve the problems you can solve, as the ‘undefined’ one’s (add the proper header file), most of the time other problems will be disappearing/solved by this.

Thanks for advice, but one shouldnt mess with the USB_API / App & Config files.....

I Found out that there is a version collision between the examples.

I tried to build an MSC interface upon the files of the CDC Example, fixed one conflict ,but I've reached the 16 KB limit, I'm waiting to get the whole license to continue next week.

It would be easier if you use

15.26 Example #CHM1: Composite CDC+HID+MSC Device; Communicate Between
Communicate Between Terminal and HID Demo App, with Two Storage Volumes............. 177

from the usb developer package and remove the HID part.

Very good idea!

How do i reduce down to 1 storage volume ?

And how should i remove the HID?

Thanks

You just use the same workspace and create a new descriptor file using device descriptor tool. while creating usb descriptor select 1 cdc and 1 msc (there is a drop down to select number of partition). It you are planning to support XP for later firmware upgrades and other operations better not to use composite device (select option for No Composite Dev in the device view).

so even if the workspace contains the HID thread it will not going to call it as you have not included it in the device descriptor.

Thanks for the proposition,

but when I replace the descriptor files, I get a whole bunch of errors.

Is there some version conflict between Descriptor files and the examples in resources explorer ?

Cheers

I think a version conflict,

i updated all my tools to the latest versions and it works now.

Thanks for the hint, I'll go play around with the software now :-)
