MFS_READ_FAULT error when SD card mount on K60

[vallinaths]

Platform : MQX 4.0.2

controller : K60

USing the example code of SD card drom path /mfs/examples/sd card .

dev_handle1 = fopen("sdcard:", 0);

if ( dev_handle1 == NULL ) {

printf("\nUnable to open SD card device");

_task_block();

}

/* Install MFS: */

error_code = _io_mfs_install(dev_handle1, "a:", 0);

if ((error_code != MFS_NO_ERROR) &&

(error_code != MFS_NOT_A_DOS_DISK)) {

printf("FATAL error while initializing: \n");

_mqx_exit(1);

} else {

printf("Initialized MFS1%s\n");

}

//open filse system

file_handle=fopen("a:",NULL);

The task is getting a error of MFS READ fault , checked the user guide of MFS which means low level driver is not respondin properly . so please let me know anybody faced same issue how to resolve it

is they any CLOCK issue which is going on SDHC CLK pin .

have you solved this problem? I met the same issue as you.

Hi,

Are you using a Freescale board (twrk60d100m, twrk60f120m or twrk60n512) ?

Could you please attach the complete code that you modified?

Have a great day,
Regards
Sol

Hi soledad

   We are using twrk60d100m tower kit , also we are trying on customised board using K60 with SD card support

if (last != inserted)

        {

            last = inserted;              

            if (inserted)

            {

                _time_delay (200);

                sdcard_handle = fopen("sdcard:", 0);

                if (sdcard_handle == NULL)                {

                    continue;

                }

                }

                {

                    printf("Error installing partition manager: %s\n", MFS_Error_text((uint_32)error_code));

                {

                    printf("Installing MFS over partition...\n");                   

                    /* Validate partition */

                    error_code = _io_ioctl(partition_handle, IO_IOCTL_VAL_PART, NULL);

                    if (error_code != MFS_NO_ERROR)

                    {

                        printf("Error validating partition: %s\n", MFS_Error_text((uint_32)error_code));

                    if (readonly)

                    {

                        printf ("SD card is locked (read only).\n");

                    }

                }

            }

            else

            {

                /* Close the filesystem */

            if ((filesystem_handle != NULL) && (MQX_OK != fclose(filesystem_handle)))

                {

                    printf("Error closing filesystem.\n");

                }

            filesystem_handle = NULL;

                /* Uninstall MFS  */

                error_code = _io_dev_uninstall(filesystem_name);

                if (error_code != MFS_NO_ERROR)

                {

                    printf("Error uninstalling filesystem.\n");

Actually disabled partion manager code part and  tried installing the MFS on SD card driver . when we opeen the filesystem getting an error " MFS read fault"

please let us know what need to be debugged.

please suggest further
