Hello Yuri,


I have successfully get access of gpio from user space and also from C Files.


now i have get a new problem while access uart2. Normal receive transmit i have performed successfully.

I want to connected Blue-tooth with uart2 and for that i have to worked uart2 with RTS-CTS  hardware flow control which is not working for me .


Port_setting.c_cflag |= CRTSCTS;        // Enable  RTS-CTS Hardware Flow Control


In code after enable the flow control the RTS pin goes high and no data will transfer from serial.
