How to interace K81 with i.MX6?

[shree97]

I want to interface K81 with i.MX6 solo/dualite over SPI interface.

I want to know whether the driver for this is already available or not?

If I need to develop the driver in which register of K81 I should write/read the data?

Please guide me regarding this issue.

Thanks & Regards,

Shree

Hi,

Yes, we do has the K81 QSPI driver ready. But I am not sure if it will work with I.MX6. Because I.MX use a different IDE(Linux or Android.)  You may make reference this thread for the IMX related:https://community.nxp.com/message/837810

Hello Fang Li,

I referred that thread but its giving example of accessing the spi device from user space.

But I want  to develop the  SPI protocol driver by treating K81 as slave device.

Kindly guide me.

Thanks & Regards,
