Forum Post: DMA with eZdsp 5535 help!

$

Hi,

I need to use DMA in eZdsp c5535 to get audio from I2S while i process previous data.

I tried using the DMA examples on C5505 but they don't work, this is the example:

 http://c5505-ezdsp.googlecode.com/files/USB_Stick_AudioFilter1.zip

when i run it i get this error while compiling: 

Error connecting to the target:
(Error -1063 @ 0x0)
Device ID is not recognized or is not supported by driver. Confirm device and emulator configuration is correct, or update device driver.
(Release 5.0.429.0)

I just need to use one DMA channel, since i'm using just one channel input, and i only need it to 
copy from the i2S to buffer while i process. As i understand it's about the simplest case possible.

Can someone upload an example on how to do this on the C5535?

Since none of the example codes worked, i basically have no idea where to begin, any help on how to get 
DMA working will be much appreciated.

Thanks in advance!
