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.(
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..
