Redefining UART ALT Modes For Pinmuxing IMX6Q

Hello guys;

 

I am working on to enable Wandboard Quad Uart 2 features for to get data from GPIO3_26 and GPIO3_27 I enabled Uart2 from dts and recompiled imx6q-wandboard.dtb file ,it seems its working but

 

when I send the "hello" to ttymxc1 I m seeing the senseless charachters , even if I adjust same baudrate ttymxc1 and my machıne ttyUSB0 (I m using usb to rs232 converter ). I think I need to close some features but I dont know what is it or I need to make some configuration pinmuxing and ALT modes .
Is there any way to change the ALT modes of the features or when we choose the UART or another features it is enabling the dependent ALT Mode ?

 

Can you give me a suggestion or what Am I doing wrong ?

 

Thanks for all ...

 

Best Regards
