How to add SD card support in the composite msd_cdc demo[KSDK 1.3]

So far the composite msd_cdc demo from ksdk 1.3 just supports ram disk application, to have the SD card support just as the dev_msd demo, you have to go through the following steps:

  • Add platform/composite/src/sdcard/fsl_sdhc_card.c and platform\drivers\src\sdhc\fsl_sdhc_irq.c to the project.

  • Add project including path: platform\composite\inc and platform\drivers\inc.

  • Change usb\example\device\composite\msd_cdc\disk.c as attached file

     Change usb\example\device\composite\msd_cdc\disk.h as attached file

     Change usb\example\device\composite\msd_cdc\hardware_init.c as attached file.

Compile the demo and let it go, the PC would recognize the MSD and CDC device,  but might need you install the CDC driver, use the one from the folder of "C:\Freescale\KSDK_1.3.0\examples\twrk60d100m\demo_apps\usb\device\cdc\virtual_com\inf".

With SD card inserted , you may see the removable disk, and format the disk just like below:

`fsl_sdhc_card.c` is already connected to the project in the driver/ folder as is the `platform\driver\src` include path
