Unable to create and save data in SD card

[ICard.2]

Hello,

I'm trying to implement a datalogger using a 32F769IDISCOVERY. I would like to be able to create a .txt file, write information on it and save this file on the SD card available on the board. The problem is, I've tried a lot of things, even followed the official ST.com step by step tutorial which is available on Youtube. The condition:

"if(f_open(&SDFile, "STM32.TXT", FA_CREATE_ALWAYS | FA_WRITE) != FR_OK)" is never executed, regardless of the code change I've already tried.

Could you help me out? Would you have an working example you could share? Thanks.

first try some search here . assuming, you are not the first and only with this problem...

search just : sdio , then sdmmc , sd card , sdcard.

after reading some of these, you get it running.

if not, come back and tell, what you tried.
