It has the NXP i.MX 6 Ultralite ARM Cortex-A7 processor. I need to transfer data at 20MB/sec to a SD card.</P><P>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?</P><P>I am concerned about the overhead the driver will impose on the overall data-rate.&nbsp;</P><P>Also, am I correct in assuming the data can be moved under DMA from a parallel input port to the SD bus</P><P>Thanks in advance,</P><P>Dan</P> Wed, 31 May 2023 20:15:34 GMT https://community.nxp.com/t5/i-MX-Processors/iMX6-SD-throughput-rate/m-p/1661175#M206893 dfasano 2023-05-31T20:15:34Z https://community.nxp.com/t5/i-MX-Processors/iMX6-SD-throughput-rate/m-p/1661985#M206957 <P>Hello</P> <P>Hope something of <a href="https://community.nxp.com/t5/user/viewprofilepage/user-id/44188">@variscite</a> team will help.</P> <P>Regards</P> Thu, 01 Jun 2023 15:34:33 GMT https://community.nxp.com/t5/i-MX-Processors/iMX6-SD-throughput-rate/m-p/1661985#M206957 Bio_TICFSL 2023-06-01T15:34:33Z
