STM32F4 DMA Interrupt big latency :(
Thanks for the response, Bernard.
The issue is that it is causing a slowdown of the DMA when there is *no* optimisation set. I’ve switched off GCC optimisation and experimented with different Debug levels (None to Max). If no code is being optimised then that should not be an issue, correct?
Also, I’m using code that came along with the Cube examples. I’ve only minimally modified it to use my own images; as I said I’ve tried using a different IDE and it works.
Thanks,
Aditya
