This time it's going to be really tough, so every suggestion is well appreciated.

I'm using SPC5 studio and I'd need to run some code just on a single core to avoid any kind of lockstep intervention. So, I need to configure the device in DPM.

Flashing the device with a modified pattern in the shadow memory lets me connect it with JTAG in DPM with no problem.

Then, starting from a LSM project, in the linker file i put 96 kB instead of 192 kB to handle with the DPM configuration. Now I'll need to add a different MMU initialization , as stated in http://www.st.com/st-web-ui/static/active/en/resource/technical/document/application_note/DM00168395.pdf , but I don't know where. As it is, the MCU hangs at startup and the main is never entered.

The main question is : is it feasibile, starting from a wizard project, of SPC5 studio for LSM to create a DPM working project?

Hello Stefano ,

Yes .. it is feasible (Cf SPC5-HAL)

you should inspire from

SPC56ECxx OS-Less Z0 Slave Core Test Application

SPC56ECxx OS-Less Z4 Master Core Test Application

and create 2 applications using the patch mode

SPC56ELxx OS-Less Z4 Slave Core Test Application

SPC56ELxx OS-Less Z4 Master Core Test Application

I have created a CR to support DPM in EL60.

Best regards

Erwan
