Hello, I am working with the AT91EB40A board and i want to read a byte
from a host PC connected to the serial B port from the board and then
send it to a Linux Host connected to the Serial A and display it in the
screen with a simply printf and vice versa.
I am using POSIX functions ( termios structure, read, write,fcntl,
threads etc). What i don't know is how i have to configure the serial
driver in the configuration tool to say my program to read from the
serial B and send it to the serial A:
should i configure this? CYGPKG_IO_SERIAL_TERMIOS;
and this? CYGPKG_IO_SERIAL_DEVICES CYGPKG_IO_SERIAL_ARM_AT91_SERIAL0
Yes :-). You want to enable all these, and also the same for the SERIAL1
stuff. CYGPKG_IO_SERIAL_TERMIOS_TERMIOS0_DEV can stay at its current setting.
Then when opening the termios devices, use /dev/termios0 and /dev/termios1.
