Hi TI Experts,

I see some of the processor pins named RSVD.

Are there some recommendations to be followed during custom board design.

    Hi Board designers, 

    Refer below section of the processor specific recommendations for connecting the Reserved RSVD pins.

    Signal Descriptions 

    Reserved Signal Descriptions

    The customer should never purposely connect anything including Test Points TPs to these pins or allow them to be connected to anything accidentally during assembly. There characteristics of these pins are not defined because the customer should never connect anything to them. 
    The device may not work as expected and may be damaged if they connected to power or ground.  The customer must ensure this never happens.

    Regards,

    Hi Sreenivasa - To clarify on your comment above. If the RSVD pin calls for a GND connection, then the RSVD pin should be connected to GND. Is that correct?

    As an example, the RSVD_t4 and RSVD_U1 pins from the AM2633-Q1 datasheet (shown below) state they should be connected to GND.

    Hello Jacob Wytick, 

    Thank you for the inputs.

    Please review the title of the FAQ. The FAQ is specific to the Sitara AM62x family of processors.

    We do not have any of the AM62x device RSVD pins that has recommendation to connect to ground.

    Regards,
