KDS3.0.0 P&E GDB server Warning 17927

Hi,

when connecting to my target hardware (KV46F) through the PE GDB and OPENSDA a warning in the console occurs several times (see below): Warning 17927. Target MCU mismatch. Download performance limited. See http://www.pemicro.com/opensda/pe_tools.cfm for information on debugging external processors.

Does anyone know what this warning means?

I could not observe any issue in download performance and my target MCU is really the right one which I selected when creating the project.

 

best regards

Guenter

Hi Guenter,

using the P&E OpenSDA, you cannot debug another processor on another board. The K20 device on your board is tight to the CPU ID on the board.

If you want to use the the OpenSDA circuit to debug a non-resident CPU, you need to use a different firmware.
