Re: Serial Port Configuration

Thank you very much, i have made the following configuration:

CYGPKG_IO_SERIAL_TERMIOS=enable CYGPKG_IO_SERIAL_TERMIOS_TERMIOS0=enable
CYGPKG_IO_SERIAL_TERMIOS_TERMIOS1=enable GYGDAT_IO_SERIAL_TERMIOS_TERMIOS1_DEV="/dev/ser1" GYGDAT_IO_SERIAL_TERMIOS_TERMIOS0_DEV="/dev/ser0"



CYGPKG_IO_SERIAL_DEVICE=enable CYGPKG_IO_SERIAL_ARM_AT91_SERIAL1_NAME="/dev/ser1" CYGPKG_IO_SERIAL_ARM_AT91_SERIAL0_NAME="/dev/ser0"


and the code you can see in the file serial.c. When compiling i receive
two errors in the open function:undefined reference to "open".

open() should come from the FILEIO package which CYGPKG_IO_SERIAL_TERMIOS requires. Are you sure your configuration is consistent?


I f i want to make a printf should now open the device(SERIAL A)
"/dev/termios0" and call the write function or call easy the printf
function as before(/dev/ttydiag)

Assuming you aren't running GDB on the same port, it's probably best to use /dev/termios0, or /dev/tty0 should work too.


You can't use /dev/ttydiag on the same port as you're running the "full" serial driver on.
