Alternatively, connect the debug cable to an additional converter PCB, which splits debug and trace signals. The converter PCB needs to be ordered separately at Lauterbach. Connect the Serial Port 0 to your target’s trace port by using the flex extension cable delivered with your accessory set.

Page 49: Debug
The 34pin debug connector should be seen as extension to Serial Port 0. The ARM-HSSTP standard defines a target connector which includes debug signals and trace signals. The debug signals are not used by the PowerTrace Serial, but they can be accessed via the MIPI-conform 34pin connector on the top of the module.
