ColdFire bdm troubles

Hi folks !!

I´m using MCF5211 and its P&E bdm to debug it (with Codewarrior 6.3 , linker 6.2).

I have 2 questions I cannot solve yet ...I hope you can help me ...

When running the debugger, I have frequently a problem releted to "loss of communication" and so I need to close the debugger screen and restart it (F5) to run again ....

A second and very strange thing is..when I get close quckly to the target, the debugger screen (and the bdm..) stops and show a Vector 0 position, as it had lead to such position due to some reason.

It happens inside our lab, a very free of noisy environment...and free of ghosts (I hope...)

I have experienced it a lot in 9S12 / 08 bdm ....

To solve this last one I believe I must consult a priest ..

Could soneone help me ?

Hello Ricardo,

With respect to item a). We found this to be a problem when dealing with the 68HC12 and its BDM. Are you using a watchdog timer? If so, has it been turned off. Having a watchdog timer turned on will interfere with BDM communications.
