Hi,

 

Could you suggest how to improve SPI speed?

We are connecting LCD(320x240) device to IMX6Q SPI interface, but its data transfer speed is slow. detail as attached

 

Free for 9.5 us per 8 bytes during transferring 320*240*2 bytes data size.

Free for 245 ns per 8 bits during transferring 320*240*2 bytes data size.

How can i reduce these free time?

 

Thanks!

Br Li
