Hi ,
I am working on M5329EVBE board running on uClinux(2.6.22).
When I configured UART baud rate as 460800 and tested, the number of bytes
received is same as number of bytes sent.
But I find data received is not proper.
But when I tested with baud rate 115200, everything is working fine.
Do we have to take care of any configuration item when using baud rate 460800.
Any suggestion would be highly appreciated.
Find the UART initialization code below
// UART initialization code
((unsigned int *)(options.c_cc))[0] = 0x157F1C03;
((unsigned int *)(options.c_cc))[1] = 0x10504;
((unsigned int *)(options.c_cc))[2] = 0x1A1311;
((unsigned int *)(options.c_cc))[3] = 0x16170F12;
((unsigned int *)(options.c_cc))[4] = 0;
((unsigned int *)(options.c_cc))[5] = 0;
((unsigned int *)(options.c_cc))[6] = 0;
((unsigned int *)(options.c_cc))[7] = 0;
tcsetattr(PziggyUartFd, TCSANOW, &options);
tcgetattr(PziggyUartFd, &options);
/*
* Set the baud rates to 460800...
*/
cfsetispeed(&options, B460800);
cfsetospeed(&options, B460800);
/*
* Enable the receiver and set local mode...
*/
options.c_cflag |= (CLOCAL | CREAD);
/*
* Enable the RTS and CTS
*/
options.c_cflag |= CRTSCTS;
options.c_lflag &= ~(ICANON | ECHO | ECHOE );
tcsetattr(PziggyUartFd, TCSANOW, &options);
Thanks and Regards
Sankar
