Problem where fopen() a bitmap file returns "Not enough space"

[t-oka]

Hello community,

■Problems occurring:

When I tried to open a bitmap file with the fopen function as shown below, 

I encountered a problem that returned "Not enough space".

Do I need to change any settings on the STM32CubeID side?

Please help us solve it.

*1. It has been confirmed that the target directory and file exist.

*2. There is enough free space on C drive.

■Environment:

・Windows

・STM32CubeIDE_1.12.1

・nucleo-f207zgt6

・C language

・001.bmp (225 KB (230,538 bytes))

■Code:

char* path = "C:\\〇〇";

fileName = "C:\\〇〇\\001.bmp";

    if (access(path, F_OK) == 0) {

        struct stat st;

        if (stat(fileName, &st) == 0) {

        if ((BmpFp = fopen(filename,"rb"))==NULL) {

            // Result of the following processing: Not enough space

            char* er = strerror( errno );

            exit(1);

        }

    }

}

Hello Oskar_H

Sorry for the late confirmation.

Thank you, the problem has been resolved.
I was able to open a bitmap with an image on a microSD card inserted into a slot using FATFS.

Thank you for your help in resolving the issue.
