Hello

 

We have a custom board with imx6 and a peripheral which communicates via SPI. The problem is the peripheral needs to be able to send data to imx whenever it wants, however since the clock and CS is not active when imx is not doing anything SPI related, slave cant send the data.

 

How do I fix this issue in Linux?

 

Regards,

Mete
