I am currently trying to figure out if it is possible to use a Lauterbach (Powertrace 3, Power Debug Pro and Preprocessor Autofocus 2) to trace the TMS570LC4357 using a custom connector using only 4 (or 8) Data Pins. From all the public information it seems like as if this should not be any issue, however the Lauterbach Tools states:
"Warning: Trace test failed: trace control pin not working
Warning: PIN TP0 connected to GND
Warning: PIN TP1 connected to GND
Warning: PIN TP2 connected to GND
Warning: PIN TP3 connected to GND
Warning: Trace test failed: pin connection error
Trace test failed.
debug port fail"
Checking the Datapins using a multimeter they do show a voltage value on them, so they don't seem to be grounded.
Indicates, that ETM Data pins 0-7 do not need to be specifically configured which is why I am stuck at trying to figure out what I am missing.
Our goal is to build a custom in house adapter to connect our custom hardware equipped with a TMS570LC4357 to the Lauterbach Hardware using 4 or 8 Data Pins.
Connecting the TMS570LC4357 Eval Board to the Lauterbach using the MIPI-60 Port works like a charm even when configuring the Lauterbach to use only 4 Data Pins as its port size.
Thanks in advance,
