MPC574xG : connection not available through laughterbach

Hello Sir,

 

I faced an abnormal JTAG phenomenon on Calypso 3M family when I used Laughterbach.

It's a simple phenomenon but I couldn't find the root cause.

When I tried to "sys.up" command on my Calypso 3M through Laughterbach, I can't attach to device and the message "emulation debug port fail" was printed.

But the weird thing is, I can definitely access to device through Multilink + S32DS combination.

Here is the device information and I would like to receive a feedback from whom had been solved this kind of problem.

Also Please refer to the attached waveform difference between Multilink and Laughterbach.

 

SPC5746CSMMJ6
1N06M
CTAA1616E

 

FYI, I didn't program any binary, In other words, it's a empty device.

 

Best regards,

Neo
