Can I use the device sai in the user space?

[delauratfrançoi]

Hello,

My name is françois. I work with imxd7. In my personnal board I have Bluetooth module. The bluetooth module is conneted with imxd7 by uart and sai port. I do not know how to use the sai port with the bluetooth module. I saw the example with sound card but it's not the same thing.

Have you got an example.

Can I use the device sai in the user space.

What should I write in device tree.

Thanks for All Help.

Best regards,

François.

Hi François

I am not aware of such ways and think that it is necessary to

write application based on sai driver, please refer to attached Linux

Manual sect.28.4.1 ASoC Driver Source Architecture. As example one

can look at Chapter 55 Bluetooth driver.

Best regards

igor
