Soon after posting this I started having build problems (see the ‘No Symbol Table’ post)

To fix that I started a new project and copied all the .c and .h files over.

Now it works (both compiler and power saving).

I think what is happening is that I modify the project with Cube while ac6 is running. As a result the .project files will become corrupt and have these strange results.

Since then I always close ac6 when running (or at least saving) with Cube. And so far I have not seen these weird build errors.

As a side note: If anyone knows how to ‘shutdown’ FreeRTOS while sleeping I would love to hear it.
Currently I have a flag I set in the interrupt routine for any interrupt I want to break out of sleep. In the sleep code I have a do while loop looking for the flag. If not seen I just re-enter sleep mode. As a result it wakes up every 1ms (to service FreeRTOS).

I don’t really want to do Tickless because I want to force the sleep mode.

I have tried turning off the system tick and restarting it, but FreeRTOS would not operate properly when I did that (even though that’s what we do in our current products - but they are an older version of FreeRTOS).
