Finally I got it working properly. Reading SDcard was very awesome for me for first time, so I decided to make a library for STM32F4xx devices and post it to my website. It’s basically just communication interface between STM32F4 and FatFS library by Chan. It supports SPI or SDIO communication. Library also supports USB communication, but for that purpose you need USB stack too. USB is available here
