C6747 High Speed USB

Hi,

Is there any example code showing how to build up a USB 2.0 High Speed communication with the PC for a Mass Storage Application, Audio Application or similar?

The examples folder of the L137 Evaluation Kit is a joke :-(

 I don't need the Linux  or ARM part of the L137.

Thanks in advance,

Udo

    Udo,

    There are plans already in place to release support for L137 USB on the BIOS platform.  I recommend that you wait for the same.  I assume you are looking for DSP side access to USB Hi-Speed peripheral.

    When you mention that the examples folder is not meeting your requirement can you pl. elaborate ?  It would help us to improve it /fix the drawbacks.  The feedback will be helpful to get the right examples to customers like you in future.

    regards

    When will the USB BIOS driver be released?  It would help us much if we could show a running application (with no Linux code) downloading a file from the PC to the DSP or doing a loopback and speedtest over USB. 

    Some feedback:

    In the past an evaluation kit would not have been released without working demonstration code doing at least an audio loopback or similar.  Unfortunately USB is not a simple think like RS232 was, and not everyone has the deep knowledge to write a DSP side USB driver in a manageable time.  Therefore software driver support from TI is even more important today.

    Perhaps my problem comes from the fact that i want to do straightforward DSP development and that the L137 development board seems to be more a gadget for Linux enthusiasts to me (it's only my first impression after playing with the development kit for a day, so please forgive me if i am wrong).  We need to verify our products at the FDA, how can we do this with 10e6 lines of Linux code in it which were never written with medical devices in mind?

    I am not sure if the new way of doing things "on the fly" is an improvement.   In my opinion the documentation and software support should have a more mature status before being released.  Nevertheless the C6747 line seems promising.

    Regards,

    Udo

    Thanks for sharing your inputs.  Can you contact your TI FAE w.r.t USBBIOS release schedules.  I am not aware of the exact schedule of availablility but expect to see it happen very soon.  What sort of application are you interested in demonstrating? The stock USB package would support MSC (Mass Storge Class) and HID (Human Interface Device) class functionalities.  If your application is not satisfied by these two classes perhaps you would have to write your own custom application on top of the BIOSUSB stack.

    regards
