dra7xx-evm board docs about dra752.pdf

Other Parts Discussed in Thread: DRA746, DRA752

Hi experts,


Based on logs on boot process, I noticed this board has been equipped with dra752 and ES 1.0. But I can find only dra746.pdf in the following website:

http://processors.wiki.ti.com/index.php/DRA7xx

http://www.ti.com/lsds/ti/apps/automotive/products.page


So here is the question:

Can I start the board from the website about its docs? Is that a right way to go?

If there is a docs dra752.pdf existed? like dra746.pdf in TI's website

Or dra746.pdf is exactly right for dra7xx-evm?

Cheers,

Zumeng

    Hello,

    The cited web sites:

    http://processors.wiki.ti.com/index.php/DRA7xx

    http://www.ti.com/lsds/ti/apps/automotive/products.page


    Contain technical briefs, that describe the functionalities of DRA7xx SoCs. They are not guides for dra7xx evm startup or TRMs.

    The appropriate guides for board bring up are the GLSDK Software Developers Guide & DRA7xx Quick Start Guide:
    http://processors.wiki.ti.com/index.php/DRA7xx_GLSDK_Software_Developers_Guide

    http://downloads.ti.com/dsps/dsps_public_sw/glsdk/6_03_00_01/exports/DRA7xx_ES_1_0_Quick_Start_Guide.pdf

    Other useful information can be found on bellow links:

    http://processors.wiki.ti.com/index.php/DRA7xx_GLSDK_6.03.00.01_Release_Notes

    http://processors.wiki.ti.com/index.php/GLSDK_Datasheet_DRA7xx_6.03.00.01

    Hi Yordan,

    Yes, I didn't want to find start guide, I just exactly want to get technical briefs, and more which describe the functionalities and detail about DRA7xx SoCs.

    So can you confirm DRA74x is exactly for DRA752 for me? Thanks in advance.

    And is there any docs to describe how the work coherency among 2xCortexA15, 2xQuadCortexM4, SGX544, C66x DSP, which I ever knew a little about them ;-)

     

    Cheers,

    Zumeng

    Hello Zumeng,

    I confirm that DRA74x & DRA75x devices are identical.

    For information about C66x DSP you can check: http://processors.wiki.ti.com/index.php/Multicore

    For Cortex A15 & Cortex M4 you should refer to arm infocenter: http://infocenter.arm.com/help/index.jsp

    Also you can go through the respective chapters in OMAP5432 TRM.

    Best Regards,

    Yordan

    Hi Zumeng,

    DRA7xx SoC is based on enhanced OMAP5 architecutre. It is used for automotive infotainment applications.

    As you can see in Section 1.3 DRA74x Functional Block Diagram from http://www.ti.com/lit/ds/symlink/dra746.pdf, the DRA7xx SoC has CAN interface, Radio Coprocessor & PWM moudles added &  Video in Ports instead of ISS.

    Additional information about Jacinto 6 devices is available under NDA agreement.

    Best Regards,

    Yordan

    OK, thanks Yordan for your tips to get these docs under NDA.

    Cheers,
