The problem is: the driver take control of the device (The device is marked UU in i2cdetect command) and do not allow to communicate in the userspace with it via I2C. The device results to be always busy. I need to send some commands to the audio chip. Is there a way to use I2C in the userspace?</P><P></P><P>Thanks in advance.</P></BODY></HTML> Tue, 21 Aug 2018 15:07:43 GMT https://community.nxp.com/t5/i-MX-Processors/ASOC-driver-I2C-communication/m-p/812302#M125258 claudiocasagran 2018-08-21T15:07:43Z Re: ASOC driver I2C communication https://community.nxp.com/t5/i-MX-Processors/ASOC-driver-I2C-communication/m-p/812303#M125259 <HTML><HEAD></HEAD><BODY><P>Hi Claudio,</P><P></P><P>You can take the following as sample for user space:</P><P><A href="https://community.nxp.com/thread/438995">Access PMIC with I2C on user space</A>&nbsp;</P><P><A href="https://community.nxp.com/docs/DOC-335597">https://community.nxp.com/docs/DOC-335597</A>&nbsp;</P><P></P><P>Regards</P></BODY></HTML> Wed, 22 Aug 2018 14:13:38 GMT https://community.nxp.com/t5/i-MX-Processors/ASOC-driver-I2C-communication/m-p/812303#M125259 Bio_TICFSL 2018-08-22T14:13:38Z
