Master-Slave Communication Between Two Jetson Nano over SPI

Hii @ShaneCCC ,

How to set to spi slave mode

Hello I want to run spi test by connecting spi1 and spi3 of jetson xavier nx board. Before connecting spi1-spi3, I connected spi1’s MOSI-MISO (spi3’s MOSI-MISO) and tested with the spidev_test.c example to confirm that tx rx works well for both spi1 and spi3. (Currently jetson xavier nx board has jetpack4.4 version installed.) Here I have some questions. How to set the master mode and slave mode when connecting spi1 and spi3? (Should I update pinmux? or https://www.jetsonhacks.com/2020/0…

Board used in above link is Jetson Xavier NX and I’m using Jetson nano after going through datasheet it seems all pins are same, so I want to ask that will it support for Jetson nano?
Also want to ask that does it work for 2 jetson nano connected via SPI?

Thank You.
