Read file from SD card

Ganesh Vaijudkar

Hello,

I am new to TI platform, working on TDA2x using vision SDK.

I would like to know, how we can read any file present on SD card from our application code? specially how to deal with this using FatFS API ? what are the changes required to do in order to read / write file from/to SD card?

Regards,

Ganesh

You need to write a driver that talks to the SD card. You plug the driver into FatFS. Here is an example for the TM4C devices: processors.wiki.ti.com/.../TI-RTOS_Examples_SerialFlash. The idea is the same. For example, the driver needs to do a disk_register that registers itself with the FatFS module. You can get more information on the FatFS module here: elm-chan.org/.../00index_e.html

Additional, you might post a thread to your device forum to see if anyone already has a driver.
