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.

Hardware environment
====================
This example runs on STMicroelectronics STM3210E-EVAL evaluation board and can be
easily tailored to any other hardware.
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
