40-pin Samtec / USB-C to USB-C (HSSTP) Switch
|
Through this hardware switch, you can conveniently connect:
•ARM HSSTP II Active Probe
•and a host PC via a standard USB-C connection
to NVIDIA Orin device (connection marked as ORIN USB-C) at the same time. This switch is optional and must be ordered separately.
A use case is that an application is programmed by the PC-based flash programming utility through the USB-C connection, and later, the application is debugged using the ARM HSSTP II Active Probe. Refer to the Technical Note NVIDIA Orin: USB port functionality switching for a use case where the switching can be automated.
Switch configuration
MODE SELECT jumper defines which connection is active.

HOST USB-C pinout
Signal Direction is described from the BlueBox perspective.
|
When initially connecting the BlueBox to a target, ensure the debug adapter pinout matches the Target connector to avoid potential hardware failure. |
Orientation
When connecting the switch ORIN USB-C connector to NVIDIA Orin target, make sure the connector is oriented correctly. Pay attention to the ORIENTATION LED indicator located on the Switch. The green LED lits when ORIN USB-C connector is properly connected to the NVIDIA target. If the red LED lits, rotate the ORIN USB-C connection.
• Red – Wrong
• Green – OK
