Hello,

I am trying to connect to an existing application running on a Aurix TC233 using the miniwiggler. I have a lot of problems connecting to the target.. the connection succeeds 1 out of 10 tries using memtool and Aurix Development Studio. I am using both memtool and Aurix development studio. Here is the connections I have:
Here are the connected pins:

TDI
TDO
TCK
TRST
TMS
Gnd
Vcc (3.3 V)

thanks

Hi vbergeron,

please can you tell me on which board your TC233 is running on? If you have a PCB developed by your own, it might be just an electrical problem.
Since PC-USB needs to see 5V, your Vcc might be to small. Another reason could be the board itself, where you might have used one of the JTAG pins
for other program based purposes.

Regards,

Jens
