Other Parts Discussed in Thread: DM3730

TI Team,

I was wondering if I could get the complete register map for the USB OTG module on the DM3730. Also, would it be possible to get obtain the source code for the bootloader?

    TI Team,

    To clarify, I'm interested in getting the source code for the Boot ROM, not the bootloader. I plan on developing my own boot loader, but I need to understand how the USB initialization works.

    David,

    You'll not get the BOOT ROM code from anywhere. It is internal to TI. You can refer to x-loader or u-boot code if required. There is USB enough code available in u-boot which initialized USB. Also you can refer to an Android boot loader where Android fast boot is used. It uses USB gadget drivers for fast boot.

    TI Team,

    I don't know, what information is covered in the "non-public" version of the TRM for the DM3730. Is it possible to see the complete non-public version ?

    If I have the be very specific, then I have an immediate need for the for the complete register map and description for the USB OTG module including the "Mentor" registers. The TRM gives only the "TI specific" registers. Also, if there is any chance to get access to the source code of the bootloader, that would be very helpful. I'm especially interested in the USB portion of the bootloader.

    David,

    Eventhough I'm not a TI employee, I may be able to answer your questions.

    Since the USB controller is from Mentor Graphics, I don't think you'll be able to get the MUSB controller documents easily. There is not TI document available for the MUSB IP. The document is basically available from Mentor. Please refer the below links for more info.
