TWR-K60F120M

Hello,

I could use some help getting an SD card up and running on TWR-K60F120M. I've been having a difficult time locating resources on the proper way to initialize this "module". I have enabled a memory card via the "Run-Time Environment" feature in Keil. The issue I'm now having is that finit("M0:") hangs but fmount("M0:") does not. Could someone please let me know the appropriate way of initializing the file system?

Below is an empty project I'm using to test with:

#include <stdio.h> #include "rl_fs.h" #include "cmsis_os2.h" #include "system_MK60F12.h" volatile int test = 0; int main (void) { SystemInit(); //osKernelInitialize (); volatile fsStatus test2 = finit ("M0:"); //volatile fsStatus test3 = fmount ("M0:"); //volatile fsStatus test2 = finit (""); while(1) { if(test++ > 500) { test = 0; } } return 0; } void Driver_SPI0(void) { }

I don't have any experience with the Keil SD card interface but if you license it from them you could ask them directly.

Otherwise there is professionally supported, off-the-shelf solution that also works with Keil at https://www.utasker.com/kinetis/TWR-K60F120M.html which allows you to immediately use the SD card by the application, including for USB-MSD or FTP/Web server usage.

It is also available in open source form if no support is required at https://github.com/uTasker/uTasker-Kinetis (also with Keil project) and allows you to simulate the TWR board, the K60F and SD card in Visual Studio.
