How do I access my SD card ?

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 ?

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.

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.

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
