Hi all,

   I found that there is a possible minimum connection for the ColdFire BDM, as listed below:

 

VDD
GND
ALLPST (connected to all four PST[3:0] signals)
PSTCLK
DSI
DSO
DSCLK
/RSTI
/BKPT
If using something other than the P&E wiggler, you don't need the ALLPST and PSTCLK signals.

 

This allow the debugging but not the tracing.

 

I think that this connection allow to set software and hardware breakpoints, to dump the ram and CPU registers.

What are the not allowed features?

 

Thanks in advance
