I have a Jetson NANO 2GB devkit. I want to understand how I can communicate between the CPU and GPU. I do not want to use any IDE. I want to understand what the physical medium is and protocol, and how I would address the GPU.
e.g. in some systems I might use I2C or SPI. But I have no idea where to find this detail for the Jetson NANO 2GB devkit.
Any help appreciated.
