[ECOS] Problem in Serial Driver

[Tathagata Das <tathagata at alumnux dot com>]

Hi,
    Currently I am trying to write a serial driver for a new platform 
on Mips.
This driver is working fine in Polled Mode but not working in Interrupt 
mode.

Printf and scanf are not working but diag_printf is working fine.
I am getting TX interrupt continously. Even when I am not using any 
printf or scanf at that time also I am getting TX interrupt.
I think, I am doing some silly mistake. I have noticed that TX buffer is 
always full.

I have done the following things :

     1. Enable CYGPKG_IO_SERIAL_DEVICES
     2.  CYGDAT_IO_SERIAL_TTY_CONSOLE  is "/dev/ser0"

  DEVTAB_ENTRY(   test,
                                      "/dev/ser0",
                                      0,
                                      0,
                                      test_serial_tx_init,
                                      test_serial_tx_lookup,
                                      &test_serial_channel
          );

Please do some help.

Thanks in advance.

Regards,
Tathagata
