HSTCU (USB-C) to Samtec22 Converter
The converter is used to connect the Infineon SGBT (HSTCU) Active Probe with the USB-C connector to a target featuring Samtec 22-pin ERF8 debug connector. The 22-pin converter must be ordered separately.
Used physical USB-C type connector doesn’t feature the USB interface as someone could presume (there is no way to incorrectly insert it), but rather the Infineon AGBT (Aurora GigaBit Trace) interface whose signals are connected to the connector in a way that USB-C connector orientation matters.
When attaching this converter to the Active Probe, make sure its marking A and marking B is aligned and matches with the markings on the Active Probe connector. |

Revision A2: Samtec 22-pin ERF8 pinout
Blue colored signals are trace signals.
*Current TriCore devices feature only one AGBT line while the Active Probe hardware is ready for future devices with more AGBT lines.
