Chris,
I've modified the Control B register to switch on RTSTX from
netarm_ser_module.h:
// before
//#define NETARM_SER_CTLB_UART_MODE (0x00000000)
// now (RTSTX = 1)
#define NETARM_SER_CTLB_UART_MODE (0x00008000)
I'm also verifying from my application that RTSTX is set everytime
that a serial message is sent but RTS doesn't go low inmediately after
completing the send. In fact I'm seeing the same behaviour than
before. What's the particular setup in your Netarm processor?
1- I'm enabling the hardware handshake in xconfig
2- Among the rest of serial config parmeters, CRTSCTS is set in c_cflag:
newtio.c_cflag |= CRTSCTS;
Am I missing any step Chris?
Thank you very much for your help.
Daniel
