STM32:FatFs库-f_mount

问题描述

我正在编程STM32F0(Keil uVision 5).

我试图使用FatFs库来管理文件系统(SD卡).我已经编写了每个初始化函数，并且该项目正在编译，没有任何错误/警告.但是第一个函数f_mount无法正常工作.函数调用为:

I am programming the STM32F0 (Keil uVision 5).

I've tried to use FatFs library to manage a file system (SD card). I've writen every initialization functions and the project is compiling without any errors / warnings. But first function f_mount doesn't work properly. The function call is:

const char sciezka = '0' ;
FATFS *fs = (void *) 0;
fresult= f_mount (fs, &sciezka, 1);

函数甚至没有通过disk_initialize到达那一行.我得到了狂热的"FR_NOT_ENABLED"(f_mount-> find_volume:::::在行fs = FatFs [vol] fs指针仍然为空之后).

带有示例的FatFs库位于fatFs网站上: http://elm-chan.org/fsw/ff/en/mount.html

Function doesn't even reach the line with disk_initialize. And I get fresult "FR_NOT_ENABLED" (f_mount -> find_volume : : : : : after line fs = FatFs [vol] fs pointer is still NULL).

FatFs library with the examples is on the fatFs website :http://elm-chan.org/fsw/ff/en/mount.html

请告诉我该怎么办.

推荐答案

您的FAFTS变量为空指针.使用局部变量.这样.

Your FAFTS variable is a null pointer. Use a local variable. Like this.

FATFS fs;
f_mount(&fs, "0:", 1);
