Other Parts Discussed in Thread: TMS320C6747

Dear Sir:

 Pls help me to answer below question. Thanks~

1. I want to run USB2.0 High speed slave mode at C6747. The software of USB2.0 (EX: USB stack....) is ready at C6747? Or I need to codeing USB 2.0?

2. When USB2.0 High speed slave mode at  C6747 is running, C6747' performance will be hold and system can't run other code? How many performance will be reduced?

3. SDRAM is needed to mount at board? Can I mount DDR2? Can I just mount one 32bit SDRAMat board?

4. About Boot mode,  Can I mount 2M bits SPI EEPROM where all code is inside?

5.  What code size of USB 2.0 High speed slave mode  is ? 2Mbit SPI EEPROM is enough?

6. The spec is shown GPIO, the GPIO can be input and output?

7.Pin USB_REFCLKIN is needed to connect to clock source? What frequence of clocj source is ?

8.The USB PHY  needs 1.8V?

9.Pin number H4 and F3 is NC at spec, but they are VSS at circuit. Which name is right?

10. In instruction, is there instruction about Matrix rotate?

11. The code of SD/MMC is ready?

12. What security protection of user code  can user use?

    Ted,

    Welcome to the TI E2E Forums!

    You will want to access the online information and documentation that we have created for your benefit. On the TI Wiki Pages, you can search for C6747 Getting Started Guide to find helpful information for downloading and installing the support software for the C6747. The PSP and DSP/BIOS packages include drivers that will help you with your questions above and your requirements; many of your questions will be answered by seeing the components in there for which drivers are available.

    Also, the TMS320C6747 (<-- click there) Product Folder has the technical documentation including the datasheet (which you have already) plus other User's Guides and Application Notes. Whenever there is a discrepancy between the datasheet and the other documentation, including the EVM schematics, the datasheet is the one to follow for best results.

    After you have looked at the software and software documentation, and the User's Guides for the various peripherals, such as the SPI peripheral, please let us know your remaining questions.

    Regards,
    RandyP
