I am going to use the Variscite DART6UL board for a project. It has the NXP i.MX 6 Ultralite ARM Cortex-A7 processor. I need to transfer data at 20MB/sec to a SD card.
Does anyone know if that kind of throughput rate is possible with the SD driver running and managing the file structure and writing operation to the SD FLASH memory?
I am concerned about the overhead the driver will impose on the overall data-rate.
Also, am I correct in assuming the data can be moved under DMA from a parallel input port to the SD bus
Thanks in advance,
