Hi, EW team:
In my Autosar project, I have EwProcess scheduled in a task of the lowest priority, so all other tasks can preempt it. When bitmap resource is loaded from external Norflash with EwCopy, preemption will interrupt the loading as well. To make use of the preemption time, I'd like to replace memcpy() with a DMA copy. So my questions are:
1. Is this idea applicable?
2. If yes, what should I take care of when implementing the DMA copy? Invalidating cache is my only concern now. I don't know if there is any potential violation against EW platform.
Thank you.
Best regards.
Stephen
