Transferring large data from DCMI peripheral to SDIO peripheral.

Hello everyone,

I'm trying to make a basic camera using 5MP camera sensor and STM32H743VI (OpenMV-H7). But as I was reading through datasheet, I realized it got only 2MB of RAM. As a result I cannot wait for whole image to come to DMA/RAM and then tranfer it to memory card, I have to transfer it row by row.

So does anyone has any idea about how to do that? Or any other solution to store image data captured by 5MP image sensor to SD-Card using STM32H743VI?

Thanks,

Tejas
