Hi All,
We have a serial port driver for general pc mother board, where we define as:
#define POR1 0x3f8
We access this port in the char driver using:
c = inb (POR1);
outb(0x13,POR1);
In the application we open /dev/SERIAL, then use
write (fd, &ch, 1) for writing to the port.
This driver is working fine with the pc motherboard, which we use to send
characters from pc to another, both running linux.
Can any clue, how to read/write serial ports in hawkboard. In the application
(on hawkboard), the call write (fd, &ch, 1), produces oops.
Thanks & Regards,
D.Giriprasad
