MFS_READ_FAULT error when SD card mount on K60

vallinaths — Sun, 27 Apr 2014 14:51:28 GMT

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 .

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);

/* Open the device which MFS will be installed on */

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

if (sdcard_handle == NULL) {

printf("Unable to open SD card device.\n");

continue;

}

/* Set read only flag as needed */

param = 0;

if (readonly)

{

param = IO_O_RDONLY;

}

if (IO_OK != ioctl(sdcard_handle, IO_IOCTL_SET_FLAGS, (char_ptr) &param))

{

printf("Setting device read only failed.\n");

continue;

}

/* Install partition manager over SD card driver */

error_code = _io_part_mgr_install(sdcard_handle, partman_name, 0);

if (error_code != MFS_NO_ERROR)

{

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

continue;

}

/* Open partition */

partition_handle = fopen(partition_name, NULL);

if (partition_handle != NULL)

{

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));

printf("Not installing MFS.\n");

continue;

}

/* Install MFS over partition */

error_code = _io_mfs_install(partition_handle, filesystem_name, 0);

if (error_code != MFS_NO_ERROR)

{

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

}

} else {

printf("Installing MFS over SD card driver...\n");

/* Install MFS over SD card driver */

error_code = _io_mfs_install(sdcard_handle, filesystem_name, (_file_size)0);

if (error_code != MFS_NO_ERROR)

{

printf("Error initializing MFS: %s\n", MFS_Error_text((uint_32)error_code));

}

/* Open file system */

if (error_code == MFS_NO_ERROR) {

filesystem_handle = fopen(filesystem_name, NULL);

error_code = ferror(filesystem_handle);

if (error_code == MFS_NOT_A_DOS_DISK)

{

printf("NOT A DOS DISK! You must format to continue.\n");

}

else if (error_code != MFS_NO_ERROR)

{

printf("Error opening filesystem: %s\n", MFS_Error_text((uint_32)error_code));

continue;

}

printf ("SD card installed to %s\n", filesystem_name);

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.
