3 SPI Interfaces - Synchronized

Hi.

I want to use three SPI interfaces available in Jetson TX2 to send data to a peripheral.

Is there a way to synchronize these three interface? I want to use the SCK signal from one of the SPI controllers as the master clock, and the data in all three SPIs to be aligned in time.
(something like QSPI, but with three data lines).

Thanks for your help.

If you are talking about all the 3 controllers to be in sync then it’s not possible. Can you clarify what’s your mean by three ports here ?

Hi

Yes I mean 3 SPI controllers in Jetson TX2.

Is it possible at all to synchronize the data packets in 3 SPI interfaces?
