    Hi Bivin,

    You can find Desktop version of the pinmux tool for AM574x device at below link:

    Latest is v4.0.1532 16-May-2019

    AM574x device has been added from version 4.0.1528 - Dec 4, 2018, refer to the release notes below:

    Hi Pavel

    In the link provided, pinmux option is not available for AM5749, it is only showing options for AM5748 and AM5746.  Please clarify.

    Bivin,

    From what I understand, you can use AM5748 option, as AM5749 and AM5748 devices are pin compatible. The only difference is that AM5749 has 2x Embedded Vision Engine (EVE) subsystems in addition. EVE is internal analytic processor without any pins.

    Hi Pavel

    Thanks for the support. I tried using AM574x Industrial Development Kit PinMux given in link below. But when i opened it in pinmux tool, it is showing 14 warnings (voltage conflict). Can i still use the same for custom board development. Please confirm.

    Hi Bivin,

    Yes, you can use idkAM574x.pinmux file as reference. It is based on TMDSIDK574 TI board, which has AM5749ABZXEA device on it.

    Regarding voltage conflicts, you can refer to the below user guide and e2e threads:

    Hi Pavel

    I modified the pinmux file as per requirement and still i'm getting error/warning which i'm not able to fix. I'm attaching pinmux file generated.

    1) Here USB DM and DP pins are having voltage conflicts.

    2) Here RTCSS OSC Xi, OSC Xo pins are having  voltage conflict.

    Do i need to consider level translators for the same. Please comment.

    Thanks

    Bivin

    Hello Bivin,

    Could you re-attach the file? Looks like it didn't get uploaded. Upload it again and we will check and get back to you shortly. 

    Thanks,

    Alex

    Hello again Bivin,

    Bivin George said:
    1) Here USB DM and DP pins are having voltage conflicts.

    For USB1, you may ignore the warning, it's there to give the designer an acknowledgment that the preferred voltage is 1V8, while some of the power rails (i.e. vdda33v_usb1) only work at 3V3 (you can see they are read-only in the configuration menu). Which is fine.

    For USB2 however, you have the option to configure the vddshv6 rail. That is, it can be working at both voltages. Right now it is set to 1V8, while your preferred voltage is set to 3V3. If you want to make this warning disappear, go in the power domain configuration menu, and set it according to your preferred voltage. If your designer wants to leave

    Bivin George said:
    2) Here RTCSS OSC Xi, OSC Xo pins are having  voltage conflict.

    The absolute maximum rating for vdda_rtc power rail is 2.0 volts. That is, it should be even less than that. See datasheet for details. Currently, the preferred voltage for the entire RTC is set to 3V3, thus the warning. Make sure you switch to 1V8 here. 

     

    Hope it helps,

    thanks,

    Alex

    Hi Alex

    Thanks for the reply. I'm having few queries.

    1) For RTCSS, if Vdda_rtc = 1.8V and Vddshv5 = 3.3V, will this create any problem. In tool, i'm not able to select Vdda_rtc to avoid warning.

    2) For USB1, you mentioned it is OK to have Vdda33V_USB1, Vdda33V_USB2 as 3.3V . Please confirm i can use Vdda33V_USB1 = Vdda33V_USB2 = 3.3V with Vddshv6 = 1.8V (as in pinmux file). In tool, Vdda33V_USB1 as well as Vdda33V_USB2 are 3.3V but why still warning is shown ?

    3) For USB2, please confirm selecting preferred voltage as 1.8V is fine (here i will get warning for DM/DP pins for not being 1.8V).

    4) Vddshv3 is 1.8V but in eval-board it is 3.3V. JTAG is connected to the same. Is this fine ?

    5) Do you have any recommendation for standard voltage to be used for any peripheral ? Is my pinmux configuration OK for normal booting , please confirm.

    Thanks

    Hello Bivin,

    I will answer all these more generally, please refer to the Data Manual/datasheet for particular electrical characteristics of each module. There each pin is said to have particular voltage requirements. From pinmux tool perspective, this configuration seems good. But I cannot confirm these, again read the Data Manual and in addition, your design should go through schematic review. 

    Thanks,

    Alex
