Device overview
A – DEBUG TOOL connector.
B – TARGET connector.
C – LED lights indicate power supply status.
If LEDs on the GI Adapter are OFF, immediately turn everything OFF! |
D – USB PD Power supply socket (PWR).
Use only original USB PD Power supply for powering and connecting with the GI Adapter, otherwise the primary functionality of the GI Adapter would be counteracted. |
E – Debug interface (SWD, JTAG) selection.
Both jumpers (SW1, SW2) should be in the same position to achieve the desired debug interface. The legend is printed on the housing.
