    SD Card Write Speed optimization

    user_148813134

      Hi,

       

      I'm using EmFile on SPI as SD card interface. Basically this works fine but the write speed is too slow for our application. Measuring the actual throughput during a write operation (suing the FS_FWrite() function) I get approx.1kB per second, where my application needs at least 5 kB/s. How can I speed up things? My bus & master clock are already set to the maximum, so I will need another trick. Any advice? (Currently I'm using EmFile V1.20. Is there a better version of this lib or are alternative file system libs avalibale?)

       

      Thanks for your reply,

      Kris
