Hi,
The board I am testing is MTRCKTSPS5744P (3-Phase PMSM Motor Control Development Kit with MPC5744P MCU).
For some reason, the download process doesn't go well.
This window pops up after failure in downloading when I click debug button.
An window pops up showing this error message.
Error in services launch sequence

Console panel displays this message.

Is there any solution you know for this problem?
Thanks.
Hello,
Is there any solution you know for this problem?
As the message explains you cannot write/read registers on the fly. First stop the execution of the code in debugger and then you can modify the registers, memory, etc...
The MPC5744P is running user code and the P&E probe is unable to halt the device, therefore all memory/register accesses fail and the download operation aborts.
This looks less like a flash programming problem and more like a debugger failing to halt the MPC5744P before download.
Is there for example SW with SWT0 enabled in the microcontroller?
Or is it a fresh sample with no SW running?
Best regards,
Peter
