STM32F4 DMA Interrupt big latency :(
Hi Aditya,
What kind of slowdown do you notice? Of course unoptimized code runs slower than optimized one, but, except if you are very close to the maximum MCU load, it should not be noticeable (except, of course, if you measure it in your code)...
As for the other IDEs, I can’t say but they may not optimize like GCC. Of course it is possible you ran in a GCC bug, but that is very improbable; I would rather bet that some code is not clean enough (either ST’s or your’s) and fools the optimizer...
