SD Card no file system error.

[demir]

Hi,

I would like to make an application to access micro sd card via SPI from STM32F407VG-DISC1 board. I have configured the pins as seen in table below.

Main file is also attached. 

However, when I run the application I get FR_NO_FILESYSTEM error. My card is formatted as FAT32. It is class4 2GB micro SD card. 

When I remove the SD card then I received another error that is FR_NOT_READY. So, this got me thinking that, I have made proper connections, but there is problem with the code.

Could you please point me to the right direction ?

 

STM32F407VG-DISC1	HW125 SD CARD MODULE
PC2	MISO PIN
PC3	MOSI PIN
PB10	SCK PIN
PB12	GPIO_OUTPUT
GND	GND
5V	VCC

Hi,

Just a question: F407 has SDIO for sd-card access -- why you dont use it ?

 

+

Keep wires to sd-card short , < 50mm is ok; long wires will make problems....

Thanks Ascha.3.

This is the task actually.

Not necessarily.

The card present/not-present might just be detected on a switch ...

Have you tried tracing back to where the error is actually raised?

Do you mean one of these?

Do you have a link to its datasheet?

Thanks Andrew.

Yes, I use one of those. I searched but cant find the datasheet.

I ve debugged the code, please see the attachment. This is where code returns no file system.

[Andrew Neil]

If you can't find a datasheet, how can you be sure you have the correct connections?

So step into find_volume() to find what causes it to return that error

Cant mark it as the solution, there is no option to select.

[Andrew Neil]

You have to un-mark one before you can mark a different one

Clikck on the in the top-right of the post:

Then choose 'Not the solution':

#UnmarkSolution

Hi @demir 

Did you figure it out this solution yourself or you follow some examples?
I only find a kind-of-official tutorial by STM staff, which, however, uses SDIO, not SPI.
