I would like establish a serial communication protocol between Raspberry Pi 4 board and Jetson Orin AGX. I am restricted to use USB type-c port of jetson as other USB ports are occupied with other sensors. Even TTL pins are occupied. Can you support me regarding the data reception through USB type-c port of Jetson ? I am using regular USB port in Raspberry Pi. Hence it is USB to USB-C communication.
Also please let me know which tty port is linked with which USB port. How can I check the list ? Are there any commands for such list or is there some documentation available ?
Hi,
If you use AGX Orin developer kit, it is not possible since the micro-B port is connected through debug MCU to the UART pins. Please check 2.1.3 section in
https://developer.nvidia.com/assets/embedded/secure/jetson/agx_orin/jetson_agx_orin_devkit_carrier_board_specification_sp
You may refer to the micro-B port on developer kit to design the type-C port on custom board.
And generally we connect to x86 host PC like
micro-B port in AGX Orin developer kit ↔ micro-B to type-A cable ↔ x86 host PC
We would suggest try
micro-B port in AGX Orin developer kit ↔ micro-B to type-A cable ↔ Raspberry pi 4
To ensure this setup works.
