OMAP1710 - Accessing audio codec from arm cpu

Hi all,

I'm a newbie in omap architectures, so I beg your pardon If my question has an obvious answer.

I'd like to know if it's possible read/write audio samples in omap1710 (it's a Nokia N80) directly from arm cpu, "bypassing" C55xx DSP. I'm developing a custom application for such a device but cannot modify DSP code.

Thanks in advance for your replies,

Best Regards,

Are you talking about N80 or N800? N80 is not running Linux - out of the box
- and more likely doesn't expose API to talk with the DSP or control the hardware. However, there is plenty of API to take advantage of the multimedia peripheral of the device.

Maybe you can elaborate a bit.

If you are able to bypass DSP, then write your own code to access DSP Mcbsp in the armside to send the audio samples. HW supports it.
