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

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.

All operation (FAT, K64, Interrupts, DMA, SDHC, SD card) simulated in Visual Studio for ease of developing debugging, learning.

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.
