hello

I have a module which has a digital audio connection (PCM) and I deal with this audio Coldfire under linux, currently working with MCF5249. Can any driver or hardware to deal with the audio in this device under linux? Another device that if you support?. I am new to Coldfire and not as well put it. thanks.

Freescale does not have a bsp specific to the 5249, but according to the appnote below, it looks like there is support for this in the uclinux kernel already.

The uclinux kernel can be obtained from the uclinux site.

hello

Thanks for responding. Already aware of this application note, thank you very much. I have a module with digital audio interface and I have never used digital audio, so you know this and embrace it as I see it as a linux device. The module consists of the following pins:

REF_CLK         output Clock
NC (FS_OUT)   input (Output) RX
REF_CLK         output TX
BITCLK           Input Reset
FS_IN             Input
RXDAI            Input
TXDAI            Output

Thanks.

Greetings
