i.MX Config Tools 24.12

[Bela1]

 Ladies and Gentlemen,

as You see on the picture above, I'm trying to configure an MCIMX7DxxVM processor's pins.

In case a pin belongs to a UART, the RxD pin is labeled as Txd, while the Txd pin is also labeled Txd.

Is this correct?

Hello @Bela1,

yes this seems correct to me.
This setting is dependent on your UART configuration. You can use DCE mode or DTE mode. Depending on which mode you use, these pins are swaped. Please look it up in the CPUs reference manual. The search for DCE only delivers few results so you should find the explanation quite quickly.

Best regards.
