Hi Lisa,
Thanks for the follow-up.
i'm not sure what you mean with the "Expressions" view.
I use the "Local" and "Watch" window to read the variables. In both cases the 64-bit values always show 0.
Regarding a test case, i would say it is simply a defined 64-bit value added to "Watch expression".
I didn't test this with an empty project though.
For debugging i found a workaroud by streaming the data out on UART and interpreting with a python script.
That helps for my purpose.
Best regards,
Sven
