2008-05-28 09:23:44     SPORT emulate UART on BF561

I am trying to use SPORT0 on BF561 as a UART. I followed the instructions in

 

http://docs.blackfin.uclinux.org/doku.php?id=sport_uart

 

to enable sport -emulation -of- UART and built the kernel.

 

I am using 2007R1 release of the uClinux distribution, but I have updated the bfin_sport_uart.c from 2008R1 for the latest bug-fixes.

 

Now when I try to test the sport-uart by

 

echo "Hello" > /dev/ttySS0,  I get '/dev/ttySS0 : Cannot create'

 

If I try to open this device from an application , I get the error 'Failed to open /dev/ttySS0: No such device or address'

 

I also found that the probe function of this driver is not being called.  Does this mean that the device has not been properly installed ? If so, then how do I make sure that the probe functon gets called correctly?

 

Regards,

 

Aparna
