Hi i am new to this,

                                 I have two custom imx6DL boards.But only one difference between two boards(i.e board A is configured with SD1 and board B is configured with SD3).

So in uboot i changed for board B SD1 to SD3 and inmachine driver itself i changed to SD3.

Both boards are configured with same UART pins.(

MX6Q_PAD_SD3_DAT4__GPIO_7_1,

MX6Q_PAD_SD3_DAT5__UART2_TXD,)

My problem is Board A receive datas from microcontroller properly through UART.

But Board B is not at all receiving datas through UART from microcontroller.

I probe the receiver pin.But its toggle.

So whats the issue?how can i solve?

please help me to identify the issue..

With regards,

R.Giritharan

Why do you configure the SD3_DAT4 pin for GPIO function? To make it work as UART RX pin, you have to configure it as UART2_RXD.


Have a great day,
