Jetson Nano SPI Interface to STM32

Hi Everyone,

I’m currently facing a problem with SPI Communication of Jetson Nano with STM32F767. Somehow the speed of the interface is Limited to 2.4Mhz and I can not find a reason why.

To verify the issue I connected a Logic Analyzer directly to the header Pins (MISO, MOSI, CLK and CS). The same problem: LA can only recept data correctly up to 2.4Mhz.

Has anyone a idea what could be the problem? What am I missing?

Hi abem1,

Are you using the devkit or custom board for Jetson Nano?
What’s your Jetpack version in use?

May I know what’s your use case?
What’s the speed of SPI you want to use?
