AM625: Pin Muxing: Voltage conflict error in SysCoinfig tool

AM625: AM625: Pin Muxing: Resource conflict error in SysConfig tool

Part Number: AM625
Other Parts Discussed in Thread: SYSCONFIG

HI TI Team,

We are going to use AM6254 processor in our custom design and we were performing pin muxing in the SysConfig tool.

We are not going to use the GPMC interface in our design, so we have some of the pins of the GPMC as GPIOs and few of the pins as PRU GPI/O pins. While doing this in the Sysconfig tool, we are seeing this warning "Ignore resource conflict with MyGPIO1."

FYI, MyGPIO1 is the label name for GPIO0 peripheral.

Please let us know if we can ignore this warning or not. Is this pin muxing okay to proceed further?

Thanks & Regards,
Sahil Nayak

    Resource conflicts such as this usually indicate two functions are assigned to the same pin and should not be ignored. I am actually surprised to see the ignore option.  

    Did you start with a 'new' configuration or with an existing .sysconfig file?

    Are you using the online tool (dev.ti.com) or downloaded.  If downloaded, which version? 

    I assume you are also using GPIO0_16?

    At what point did the resource conflict appear? 

    Can you share your .sysconfig file?

    I also notice that all the signals and peripheral are 'locked', at least in what you show.  Are you locking at the end, or as you select/configure each peripheral?

    Hi Paul,

    Thank you for your response.

    I was able to resolve the conflict.

    I had unticked the box from MyGPIO1, but didn't change the pin name to Any, which led to a conflict.
