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.
