Pic FSInit（）；CE“坏分区”；

我使用的是PIC18F26K80和XC8编译器。我正在尝试初始化SD卡并创建一个文件。我只是在Windows上格式化SD卡，使其具有“FAT32”文件系统和512字节的“分配单元大小”。SD卡的容量为2GB。我正在使用MLA遗留版本中的MDD库。我的主要意见如下：

FSFILE * file;
char sendBuffer[22] = "This is test string 1";

//**************************************************
// main function
//**************************************************

int main()
{
    initIO();
    LATBbits.LATB0 = 0;

    // Initialise SPI and SD-card
    while ( !MDD_MediaDetect() );

    // Initialize the device
    while ( !FSInit() );

    // Initialize 
#ifdef ALLOW_WRITES

    // Create a new file
    file = FSfopenpgm ( "FILE.TXT", "w" );
    if ( file == NULL )
        while(1);

    // Write 21 1-byte objects from sendBuffer into the file
    if ( FSfwrite ( (void *) sendBuffer, 1, 21, file ) != 21 )
        while(1);

    // Close the file
    if ( FSfclose ( file ) )
    while(1);

#endif

    LATBbits.LATB0 = 1;         //LED

    while(1) {}

    return (0);
} 

//==============================================================================
// void initIO( void );
//==============================================================================
// Sets the pins on the PIC to input or output and determines the speed of the
// internal oscilaltor
// input: none
// return: none
//==============================================================================
void initIO()
{
    OSCCON = 0x75;                  // Clock speed = 32MHz (4x8Mhz)

    TRISA = 0;
    TRISB = 0;
    TRISC = 0;

    TRISBbits.TRISB0 = 0;           //LED

    TRISCbits.TRISC3 = 0;           // set SCL pin as output
    TRISCbits.TRISC4 = 1;           // set RC4 pin as input
    TRISCbits.TRISC5 = 0;
    TRISAbits.TRISA5 = 0;
} 

程序卡在函数“FSInit（）”中，我从函数中得到的错误是“CE_BAD_PARTITION”，这意味着“引导记录不好”

“initIO（）”函数如下所示：

FSFILE * file;
char sendBuffer[22] = "This is test string 1";

//**************************************************
// main function
//**************************************************

int main()
{
    initIO();
    LATBbits.LATB0 = 0;

    // Initialise SPI and SD-card
    while ( !MDD_MediaDetect() );

    // Initialize the device
    while ( !FSInit() );

    // Initialize 
#ifdef ALLOW_WRITES

    // Create a new file
    file = FSfopenpgm ( "FILE.TXT", "w" );
    if ( file == NULL )
        while(1);

    // Write 21 1-byte objects from sendBuffer into the file
    if ( FSfwrite ( (void *) sendBuffer, 1, 21, file ) != 21 )
        while(1);

    // Close the file
    if ( FSfclose ( file ) )
    while(1);

#endif

    LATBbits.LATB0 = 1;         //LED

    while(1) {}

    return (0);
} 

//==============================================================================
// void initIO( void );
//==============================================================================
// Sets the pins on the PIC to input or output and determines the speed of the
// internal oscilaltor
// input: none
// return: none
//==============================================================================
void initIO()
{
    OSCCON = 0x75;                  // Clock speed = 32MHz (4x8Mhz)

    TRISA = 0;
    TRISB = 0;
    TRISC = 0;

    TRISBbits.TRISB0 = 0;           //LED

    TRISCbits.TRISC3 = 0;           // set SCL pin as output
    TRISCbits.TRISC4 = 1;           // set RC4 pin as input
    TRISCbits.TRISC5 = 0;
    TRISAbits.TRISA5 = 0;
}

尝试使用SD卡格式化程序格式化SD卡。选择选项为“完全擦除”，然后它将擦除SD卡的所有部分，这是普通格式选项无法做到的。从这个链接下载：@Amol我试过了。它确实抹掉了一切，但我仍然得到同样的错误。
