Hi everyone,

I am trying to send some bytes of data on a sd-card (8GB) using SPI.I started with wiring the sd slot and configuring the spi but I have nothing, not even the clock...I have followed what's explained in the file spi.h and seen other post about spi but I still don't see where I am wrong.I'd really appreciate if you can help me with it ! Thank you. #spi-sd-card-stm32-discovery

Hello,

I finally found something !I had changed the ''1b'' of the bus width for ''4b'' in the error function instead of  init function...Now the ''SD_Init()'' function returns ''SD_START_BIT_ERROR''.I have followed the code and arrived at a function that returns this error if the SDIO_FLAG_STBITERR != RESET.My SDIO CLK is stuck at 400kHz even if I don't divide it... Any idea of where it comes from ?Also, should I Enable the SDIO_ClockBypass ?Thank you.

Hi 

i am using the stm32f10b eval board and i want to save a text file into a micro sd card ,i know that i should use the fatfs file system but i am not able to integrate the library in my project .so my question is there a library distinated to stm32f10b or someone who had used it.thanks

I'm not using the F1 commercially and don't have an STM3210B-EVAL. I think it uses the SPI bus to access the cards, and the V3.5.0 library looks to have SPI_SD support code, and projects for the EVAL board.
