ADSP21161 EZ-kit SPORT problems...

Started by Unknown July 3, 2003
Hi,

I've recently started up my 'ADSP21161N EZ-LITE' development kit. When I try
to use the serial port the serial port interrupt is continously triggered
and the program gets into a locked state.
Why is the port triggering, there is nothing connected to it?
The serial clock and the frame is generated internally.
Whatever SPORT (0,1,2,3) i use I get the same result. As soon as I enable
it, it locks up with incoming interrupts. Regards,
Ulf Ohgren



Try do disable the interrupt source inside
the service routine and see which one helps.
Had something like that when I forgot
to serve the second half of the port.
For example SPORT0 channel A+B active,
you get an interrupt for transmit and only fill
channel A with data, after I filled both it went away.
