Example description =================== This example provides a basic example of how to use the SDIO firmware library and an associate driver to perform read/write operations on the SD Card memory mounted on the STM3210E-EVAL board. Below is a description of the different example steps: - Configure the SDIO according to the desired SDIO_CK clock frequency. - Reset the SD Card - Identify the SD Card - Initializes the SD Card - Get the SD Card Info - Select the SD Card - Enable the Wide Bus mode (4-bit data) - Erase the correponding blocks - Read the Erased blocks - Test if the corresponding Blocks are well erased: check if the EraseStatus variable is equal to PASSED. - Set the Data Transfer Mode to DMA - Write a single Block - Read a single Block - Comapare the written Block and the read one: check if the TransferStatus1 variable is equal to PASSED. - Write multiple Blocks (2) - Read multiple Blocks (2) - Comapare the written Blocks and the read one: check if the TransferStatus2 variable is equal to PASSED.
