SD CARD DATA LOGGER

Sir/Ma'am,
I am trying to interface Sd card with STM32F4 using SPI protocol.
I am using HAL library.
But I am having problems in SD card initialization , read and write functions.
Hope I will get some help from here.

Thanking you.

You will probably get better results from a specialist STM32 website.
If you want to try here, please post enough of your code to demonstrate the problem.
Which compiler are you using ?

Which library or driver are you using for SD card initialization?

I am using STM32 cube MX and Atollic truestudio softwares.
I am also using HAL library.
and the FATfs I have initialized in STM32 is user defined.
