Thanks Mr.Jifl.

In i386 pc target i used hal_diag_init() and hal_diag_read() to get input
from target keyboard.
MBX starter kit also has a keyboard interface support. If i try to use the
hal_diag_read() system call it reports unreferenced symbol error. What is
the option which i need to enable to get input from target keyboard.

Thanks,
mekala

Do a

#include <cyg/hal/hal_diag.h>

and then use the macro

HAL_DIAG_READ_CHAR(x)

where x is a char to read into, e.g.

char foo;

HAL_DIAG_READ_CHAR( foo );

I believe this should work.

[ECOS] Reg::input from keyboard

[Natarajan, Mekala (CTS)]

Hi,
	i am using MBX starter kit with MPC860 50MHZ processor. This kit
has two serial ports and keyboard interface too. I am using ecos latest cvs
version.
How do i use the serial port 2 for getting input or for diagnostic output.

Regards,
mekala

Diagnostic output can go there by using the options in the MBX platform HAL
such as "Diagnostic serial port"
(CYGNUM_HAL_VIRTUAL_VECTOR_CONSOLE_CHANNEL) and switching it from 0 to 1.

Input is something best done with a proper interrupt-driven serial driver.
If they are included in your configuration the port 2 driver is enabled by
going into the I/O serial configuration and enabling "HArdware serial
device drivers" (CYGPKG_IO_SERIAL_DEVICES) and selecting it under there.

You could then do I/O using the more native cyg_io_read/cyg_io_write
commands described in the documentation, or by using /dev/tty2 (probably)
with stdio for tty-like access.
