I am wanting to run in DPM .  I use SPC5Studio to create a .wsx configuration to debug with, but I get the following failure when I try to connect to the target:

----------------------------------------------------------

Connection Failed Report from

I can connect and debug in LSM just fine.

Hello Matthew ,

I have never tested DPM Configuration  with PLS UDE 4.8

I am asking to the application team.

          Best regards

Hello Matthew ,

Itis mandatory to enable the DPM through the LSM_DPM user option bit in the shadow block of the flash

memory. For more details, please, refer to the SPC56EL Reference Manuals.

I am contacting PLS Support how to do that by PLS USB/JTAG.

In attachment, an example how to enable DPM with TRACE32

Best regards

Erwan

Hello Matthew ,

Yes , it should work , but you need P&E Debugger stuff to do that.

Is there an 'Execute Initialization Commands on reset' that would set this register?  Am I the first to use the SPC56 decoupled, with PLS?

Hello Matthew ,

There is FAQ on PLS side

Having a pretty tough time finding either a MemTool plugin for SPC5Studio, or the addin for PLS-UDE.

I think the issue is the PLS-UDE website is a bit re-arranged and I will contact them.  Erwan, please keep up the fantastic work.
