SPI Transmit in slave mode

Hi guys,

 

I have my 21489 EZ Kit hooked up to an ARM micro, trying to get them talking over SPI with the Sharc configured as a slave. I can read in data from the ARM, but having difficulty transmitting data from Sharc to ARM. I'm pretty sure I have it configured correctly, so I'll save posting code for now, just a general question. If I have a local buffer of data, is it possible to chain SPI DMA the full buffer (say 20 ints) out to the MISO line? I tried, but only ever see the first int in my buffer being transmitted on a scope.

 

Thanks

Brian
