Hello.

I am working on a project in which i have to grab data from DCMI and store it to SDIO. Both of these periphirals are using DMA2. I have tested SDIO and it is perfectly working with DMA2. Now i have a bit of confusion that how data is handled; if both of the periphiral modules are using DMA2. What are the chances of losing data? If any body has done this before kindly share your experience.

DMA2 has multiple streams, your primary issue is likely to be the disparity of In Flow and Out Flow rates of your respective devices.
