I have paired a micro controller to the Jetson TX2 using I2C. The micro controller’s I2C bus can reach speeds of 6MHz (3MHz without overclocking the CPU). The Jetson’s I2C speed is set to 400 KHz.
According to “Jetson TX2 System-on-Module Data Sheet” page 38 section 4.7 the Jetson has Standard-mode (up to 100Kbit/s), Fast-mode (up to 400 Kbit/s), and Fast-mode plus (Fm+, up to 1Mbit/s).
I would need to activate Fast-mode plus to receive the data transfer speeds I need.
