debug board

paolomartinelli — Thu, 04 Feb 2016 15:07:05 GMT

Hello,

I am trying to debug SW using CodeWarrior 63SE, Cyclone PRO and a board (with MC908JL16 on it).

I cannot connect to the board when running. The connection between Codewarrior and the micro is done as in attached doc.

I use IP connected Cyclone (the connection works with programming tool).

It is my first time, so I do not know how to proceed.

I start debugger from Codewarrior.

Any help ?

Regards,

Paolo Martinelli

Hi Paolo,

You are using the correct pins but you need to make sure that the connection between the board and the Cyclone Pro MON08 connector is correct, you can use as reference the following image:

Hope it helps!

Hi Carlos,

thanks for the reply. All connections are as in the picture.

I think I have understood the mistake. In fact the person who did schematic (and board) has used pin PTB0 as functional pin (reading a pulse coming back form fan, to detect its working). I will manage to modify this.

I still have a question:

I have cyclone pro configured (through switches) to provide power and clock to the board when programming it. Should I change this behaviour to debug the sw while normal working ?

I have another issue. I am not able to use USB when debugging. Only available ethernet connection. Is it correct ?

The Cyclone is connected through USB cable and this connection works with PROG08SZ tool. It does not with codewarrior.

Hi Paolo,

It is good to hear you found the problem.

If while normal working the MCU is self-clocked and has its own power supply then you need to change the jumper setting and also update the debugger settings:
