Pin config warnings

[jasonedn]

When the SAI pins were configured, the "Arrow" warnings were reported on some pins as shown below. Actually these pins were configured for SAI and they couldn't be edited. It worked but I wanted to remove these warnings. Your help are appreciated.

Hi @jasonedn, 

For this error you will need to change the routed pin/signal for GPIO to the correct SAI pin, because for GPIO there are two directions input/output but for SAI the direction is input and is set automatically. 

If you have any questions or concerns, don't hesitate to let me know. 

Have a great day!
