[ECOS] /dev/serx device driver

["Ricardo Andrino" <ricardo_andrino at web dot de>]

Hello,
after several temptations i couldn't see the output of printf (hello.c) function without using Redboot. I don't  know if that can be really made. My actual configuration is as follow:

*AT91EB40A
*Serial A, port 0
*COM of Pc to download the programs and connects to Angel Monitor:/dev/ttyS0

*CYGDAT_IO_SERIAL_TTY_CONSOLE = /dev/tty1 (my actual console)
*CYGDAT_IO_SERIAL_TTY_TTY1 = enable
*CYGDAT_IO_SERIAL_TTY_TTY1_DEV = /dev/ttyS0 or /dev/ser0 ?

*CYGPKG_IO_SERIAL_DEVICE = enable
*CYGPKG_IO_SERIAL_ARM_AT91_SERIAL0 = enable
*CYGPKG_IO_SERIAL_ARM_AT91_SERIAL0_NAME = /dev/ser0

*CYGDAT_LIBC_STDIO_DEFAULT_CONSOLE = /dev/ser0 or /dev/tty1?

When i type this command ls -lisa in the /dev directory no /dev/serx appear.I don't know if ecos make it or should i./dev/ser0 is the physical driver for port 0 isn't it?

I think that when the program running on the board finds a printf function must write the strings in the serial device output buffer and then send them to the /dev/ser0 (port 0 for the board?).The Pc must read them in /dev/ttyS0 and finally send them to a terminal, in my case /dev/tty1.is something wrong in all of this? Are all connection describing above correct? Why my program hangs up when runnig but is downloaded correct?

I do aprreciate any kind of help because i have tried to make it for 2 days without success.

Thanks a lot
