Device Tree • Re: CM4 failed to enable uart3 + 485 mode

I think all you need is this - drop fragment 2:

Code:

fragment@1 {target = <&uart3_pins>;__overlay__ {brcm,pins = <4 5 6 7>;brcm,pull = <0 2 2 0>;};};

Hi PhilE, thank you, it works! But is there a way to enable only gpio 4, 5 and 7, to spare gpio 6 to other use (I not need CTS signal) ?
