hello all,
can any one tell me how to do loop back programing and how to set hardware for
this in ADSP 21262.
i tried to configure SPORT0 for tx. and SPORT 1 to rx. but i am geting error
saying: "core access to SPORT/LINK port is hung at PC:0x080286"
Please tell me solution for this.
Thanks
Abhi

Sounds like an attempt to read or write is locking up the processor.
This will happen if you try to read an empty input register or write to a
full transmit register. Disassemble location 80286 (strange, reminds me
of a very old processor...) and see which it is. Most likely you have to
check a status register first, then do the operation only if data is
available for a read.
You probably want to put in a time out as well - if you don't get any data
after x milliseconds, figure there's no more coming.
Patience, persistence, truth,
