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 or Thor device (connection marked as TARGET 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 Switch NVIDIA Orin or Thor USB port functionality with mDIO port for a use case where the switching can be automated.

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 TARGET USB-C connector to NVIDIA Orin or Thor 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
