Sport communication

Started by ashr...@rediffmail.com June 3, 2009
hi everybody,
I tried to establish sport comm between adsp2181 and BF533.
could not succeed.
I tested separately both 2181 and BF and are working fine.
I tried using loopback mode ( DT connected to DR of same processor)
and it worked but when it comes to interfacing its not working.

what could have gone wrong?
First of all are the 2 processors compatible ( i mean can i really
establish sport comm between the two.voltage levels of both must be compatible)

Is the SIC_IMASK interrupt config necessary even when not used in DMA mode? because when i tested loop back config for BF i had not configured
interrupt registers and still it worked.
