Thanks a lot Jonathan, but could you give me a little detail how I can use
the diag_printf(). I changed it to following:
void cyg_user_start(void)
{
diag_printf("Hello everyone\n");
}
but still no output from the console window (in Insight)
but when I load the program via hyperterminal as:
load -m xmodem
go 0x040000
then I can see the output from the hyperterminal. Did I miss anything for
the mangler?

You forgot the trailing \n. The GDB 'O' packet (in the remote protocol)
output is line oriented.

load -m srec and then send the file using hyperterminal's send file
functionality. There's a timeout so don't hang around though! However we
did sometimes find hyperterminal to be unreliable in the past.
