Sample code for card detection, read/write operation on MMC or eMMC card?

Mark Utter

Where can I get a sample code for card detection, read and write operation on MMC or eMMC card? The code may be meant for any ARM Cortex-A8 platform (OMAP35x or DM816x or DM814x etc).

Thx,

Mark

Hi Mark,

The diagnostic routines for OMAP3EVM and DM814x EVM include SD/MMC test which perform detection, read and write operation.

You can find the sample snippet a2330.sdmmc.zipttached.

Hope this helps.
