- 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) -
