SPI on Jetson - Using Jetson-IO - JetsonHacks
May 4, 2020 · The introduction of JetPack 4.3 brings with it a new tool, Jetson-IO. All of the Jetson developer kits include a 40-pin GPIO expansion header. Many of the pins can be used either as General Purpose I/O (GPIO) or Special Function I/O (SFIO). SFIO are functions such as I2C, I2S, SPI, and so on.
Jetson Nano - Using I2C - JetsonHacks
Jul 22, 2019 · There are also provisions for Serial Peripheral Interface (SPI) ports. In the default Nano Image configuration, the Jetson Nano does not have SPI port access. However, the device tree can be reconfigured for accessing SPI through the J41 Expansion Header. In the Jetson Nano J41 Pinout, NVIDIA recommends placement for two SPI ports.

I2C pins to GPIO on Jetson Orin Nano Dev Kit - Jetson Orin Nano ...
Oct 9, 2024 · I have a simple task to use I2C pins as GPIO due to their high current drive strength. But I am unable to do so as Jetson-io does not give control over i2c. My question is can I do it by defining device overlay or it is essential to change main the device tree file?
Master-Slave Communication Between Two Jetson Nano over SPI
Jul 19, 2022 · For the master, I have put pin 24 (SPI_1_CS0) to pin 2 (5.0 VDC). I intended to set it high for it to become the master. I have used /opt/nvidia/jetson-io/jetson-io.py to configure the pins. After running sudo modprobe spidev the pins were configured. Output of ls /dev/spi* is.
