I have interfaced 256Mb sdcard with stm32f051 using FATFS driver, find_volume() function is giving FR_NO_FILESYSTEM response because ld_word(fs->win + BS_55AA) != 0xAA55. Please give me some solution for this issue.

Note that FatFs is 3rd-party software - nothing to do with Keil or ARM:
In particular, note the 'Resources' links at the bottom of the page.

So is there actually a File System on your card?

Really? That must be a very old card! Are you sure it's still working?

What debugging have you done to find the problem?
