How do I access my SD card ? Is there a device driver for SDHC for my FRDM-K64 board ?
What file system should I be using to access the SD card ? Are there any examples ? Is there any documentation of this process ?
Hello Randy,
Download the official SDK for your Board from here:
https://mcuxpresso.nxp.com/en/select
You will find an example for fatFS in it, together with many other examples and drivers
Best Regards
Hi
Or use https://github.com/uTasker/uTasker-Kinetis
More powerful interface than FatFs, integrated into USB-MSD, works with memory sticks and directly accessible by FTP or web browser.

Most of the SDK's out there are based around Chan FatFs (http://elm-chan.org/fsw/ff/00index_e.html). Take a look in your SDK's example projects, you'll find something there.
