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.

Note: make sure that the Jumper 17 (JP17) is closed and Jumper 20 (JP20) is open in STM3210E-EVAL How to use it ============= In order to make the program work, you must do the following: - Create a project and setup all your toolchain's start-up files - Compile the directory content files and required Library files: + stm32f10x_lib.c + stm32f10x_gpio.c + stm32f10x_rcc.c + stm32f10x_nvic.c + stm32f10x_flash.c + stm32f10x_sdio.c + stm32f10x_dma.c - Link all compiled files and load your image into either RAM or Flash - Run the example ******************* (C) COPYRIGHT 2008 STMicroelectronics *****END OF FILE******
