Forum Post: RE: MMCSD With FatFs Problems

Hi Dave,

Thanks for your post.

We do have starter ware GPIO example source for OMAPL138 LCDK for ARM core to detect the status of MMC/SD card insertion/ejection using GPIO pin configured in pinmux settings.

You shall integrate & add the GPIO source code with thirdparty FatFs files  into your project and test the status of SD card (Read/Write) by generating an GPIO interrupt. Please find the attached gpioCardDetect.c source.

You shall also able to download the complete OMAP-L138 Startwe ware package from http://www.ti.com/ and please find the path below for the CCS project for GPIO starter ware example on LCDK OMAP-L138 ARM core.

Alternatively, you shall also use the MMC/SD test code on ARM core, but for OMAPL138 experimentor kit (Zoom). Please find the attached zip file for the BSL (Board support library) test code for MMC/SD, in which you have the CCS project for windows platform.

But, you should customize the Pinmux settings for the LCDKOMAPL138 board you have & integrate with the above BSL test code for MMC/SD on ARM core and you can try testing the MMC/SD card status.
