I'll have to recheck, because I'm getting the same error:

Hi Jan,

I'm using the RM48L952 along with HALCoGen and CCS (possibly newer versions but that should be fine) and the SanDisk EDGE 4GB microSD. Anyways, I have managed to get all the way through part 2 of your walkthrough. I can successfully connect through SCI, and I am attempting to communicate with the microSD card. However, when I run my code I get an error message returned to me in my terminal: "f_mount error: FR_NOT_READY". It's fairly obvious that the code is failing when it calls SD_Test(); because that is the only place where "f_mount" is used. FR_NOT_READY is defined by "(3) The physical drive cannot work", which brings me to my question/concern. Does this error message mean that my SD card is ruined? Or does it mean that the commands I'm trying to use are incorrect with respect to the SD card that I am using?

Any clarity that you could provided regarding this issue would be greatly appreciated!

Hi,

First, I started using TI sample code and the program worked for opening files from the SDCard.

Then, I downloaded your source.zip and it is missing some header files, such as #include "sd_defs.h"

Please, could you help me?
