RE: [ECOS] LIBC and STDIO

Thanks for replying.  Sorry I forgot to mention that I'm using AEB-1 rev. C


I do have the serial package enabled.. some of the defines are here:

#define CYGPKG_IO_SERIAL_TTY

#define CYGPKG_IO_SERIAL_TTY_TTYDIAG
#undef  CYGPKG_IO_SERIAL_TTY_TTY0
#define CYGDAT_IO_SERIAL_TTY_TTY0_DEV "/dev/ser0"
#define CYGPKG_IO_SERIAL_TTY_TTY1
#define CYGDAT_IO_SERIAL_TTY_TTY1_DEV "/dev/ser1"
#undef  CYGPKG_IO_SERIAL_TTY_TTY2
#define CYGDAT_IO_SERIAL_TTY_TTY2_DEV "/dev/ser2"

#define  CYGPKG_IO_SERIAL_ARM_AEB
#define  CYGPKG_IO_SERIAL_ARM_AEB_SERIAL0
#define CYGDAT_IO_SERIAL_ARM_AEB_SERIAL0_NAME "/dev/ser0"
#define CYGNUM_IO_SERIAL_ARM_AEB_SERIAL0_BAUD 38400
#define CYGNUM_IO_SERIAL_ARM_AEB_SERIAL0_BUFSIZE 128
#define  CYGPKG_IO_SERIAL_ARM_AEB_SERIAL1
#define CYGDAT_IO_SERIAL_ARM_AEB_SERIAL1_NAME "/dev/ser1"
#define CYGNUM_IO_SERIAL_ARM_AEB_SERIAL1_BAUD 38400
#define CYGNUM_IO_SERIAL_ARM_AEB_SERIAL1_BUFSIZE 128

io write to /dev/tty1 or /dev/ser1 directly works fine.  However the libc
printf doesn't like it.  I guess I'm still missing something.  Changing
CYGDAT_LIBC_STDIO_DEFAULT_CONSOLE back to "/dev/haldiag" will work, but it
prints out some garbage only GDB will understand.

thanks again
