SD Card mounting error- FR_DISK_ERR, disk error occurred

[KhushJain]

I am using STM32L562 microcontroller. I am unable to interface it with sdcard using sdmmc and fatfs
my sd cards are- 8gb (formatted in fat32)[old], 32gb(unused)[new]. In both sd cards I am getting the same problem- disk error occurred (FR_DISK_ERR) it means disk is not initialized properly but I have checked the hardware and it has no problem, what should I do??

Read here in forum (search sd card problem etc , my posts ...) , to see the "usual" problems and what to do.

Should solve your problem.

i have tried all the suggested solutions on different forums but it is still not working

So:

- whats your setup (in Cube) now for sdmmc  ? (show screens)

- How is your hardware now ? (What you tried/changed)?

- What you do in your software and which error you at which point? (what you tried else, to find out, why ?)

So have you stepped through the code to find exactly what is causing that error to be returned?

Have you used an oscilloscope and/or logic analyser to see what the hardware is actually doing?

Post full hardware details for others to review?

Does a standard ST example on an ST board work?

 

PS:

What SD Card driver/middleware are you using?

Failure tends to cascade. Instrument the sector IO, see which succeeds or fails and the point at which that gets reported at the top level. Usually a lot later.

Debug based on an understanding of what's actually failing
