Part Number: AM625
Other Parts Discussed in Thread: AM62A7,

Tool/software:

Hi TI Experts,

I have the below query

AM62A7: How can we change the drive strength of the SPI interface
AM625: How to change the drive strength of the ethernet interface IOs
AM625: How to change the drive strength of the OSPI interface IOs

In general can i configure the drive strength for the SOC IOs or peripherals.

    Hi Board designers, 

    The only supported drive strength is the default drive strength.
    We do not currently support changing the drive strength.
    The SOC was designed for proper operation when using the default drive strength.
    Changing the drive strength may cause functional issues. Therefore, we currently do not support changing drive strengths.
    The drive strength must remain in the default state since this is the only condition used during timing closure of the peripherals.

    We only support the default drive strength, and customer should use the device IBIS models to understand the actual output buffer drive strength.

    Regards,

    Hi TI Experts,

    Do you have plans to support other drive strengths other than the default drive strength?

    Hi Board designers, 

    We do not currently support changing the drive strength.

    We have received similar requests. The Systems/Design team is reviewing, analyzing the requests.

    I have no additional inputs or timeline for inputs.

    I will update the FAQ when i hear from the team.
