AM5728 Pin Mux Tool won't allow RX check box to be unchecked

I want to use GPIO4_0 on pin G6 as an output but the pin mux tool won't let me deselect the RX check box. What does that mean?

Please post your pinmux file.

Disabled RX box means signal can only be used as input. There is a restriction on GPIO1_0 through GPIO1_3 which can be only inputs. There is no restriction for other GPIOs. So looks like it's a bug in the other GPIOs (GPIO4_0 for example) where this box should enabled for clicking. Internal bug report has been filed and tentative target is to get it fixed in next version.

Thanks.

I zipped the pinmux file. Here it is. I also found that GPIO8_3 would not let me uncheck the RX box.

Yes, like I said above it's a bug and we are looking into it. Should be fixed in next version.

Thanks,
Alex
