Hi Ziyang,

So this change will have the effect of changing the console on ipq5018-rdp432 from gpio31-gpio34 to gpio28, gpio29.

Have you verified that change on hardware or the schematic ?

This has the wrong UART pinout ?

Is this change something that should be expressed for a particular board ?

 Infact again checked it, the correct pins are "gpio20", "gpio21".
 It works so far because u-boot has configured it.
