I'm reading data from a UART with DMA and want to write that data to an SD card (on a F722). Since the data is much longer than my buffer, I chose circular buffer for the DMA.
The problem now is that I need to save the receive buffer to SD occasionally, but how do I know when I need to do this?
Can someone recommend the best approach here, using Cube HAL:
I'd really appreciate some ideas. The Cube examples are way too simple.

I'll have to go dig, probably talking 6-7 years ago, and 2-3 forum transitions. Looking at the Google Drive it was likely a forum attachment, a lot of that stuff got destroyed by ST in the process(es).
