We are running a survey to help us improve the experience for all of our members. If you see the survey appear, please take the time to tell us about your experience if you can.
we made some simple tests with STM32F100 Value Line Eval Board:
//------------------------------------------------------------------------------ // Variables static unsigned char sDstBuf[1024]; // 1KiB static unsigned char sSrcBuf[sizeof(sDstBuf)];
printf("Copying words from misaligned src to aligned dst buffer... "); memset(sDstBuf, 0xcd, sizeof(sDstBuf));
with optimize Level 3, optimize for time this takes 120usec
with optimize Level 0 155usec
almost the same if memcpy is used: memcpy(sDstBuf, (const void *)0xcd, sizeof(sDstBuf));
It runs into hard fault, if optimize Level >=1 and optimise for time is not set.
I think this is a compiler error..
We ran into this before with MDK 4.60, now we use 4.70A

Who do you think you are directing your late response to?
And who do you think you are? Let's see: so far all you've exhibited here is
a) a knack for totally missing the topic of discussion in every single one of your three, well, "contributions", b) a total lack of understanding of the medium you're using, and c) a strangely narrow selection of targets for your insinuations: me
Here's some free advice for you: the next time you decide to launch a random campaign of throwing stuff at someone, you might want to step out of that glass house of yours, first.
And who do you think you are?
I'm one who knows how to use a search facility effectively. It's interesting going back to see historical posts.
