(0x30aa) PMGR INVALID PARTITION error while mouting the SD card file system

vallinaths — Fri, 25 Apr 2014 18:49:34 GMT

Working on example program of MFS sdcard example that represents my case but it doesn't work:

Platfrom : MQX 4.0.2GA build

Controller : K60

char filesystem_name[] = "a:";

char partman_name[] = "pm:";

char partition_name[] = "pm:1";

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

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

...

/* Install partition manager over SD card driver */

error_code = _io_part_mgr_install(sdcard_handle, partman_name, 0);

/* Open partition */

partition_handle = fopen(partition_name, NULL); -->return Error

By step into debug mode i see that error is generated in

int_32 _pmgr_get_part_info

(

PART_MGR_STRUCT_PTR pm_struct_ptr, /*[IN] the partition manager information */

PMGR_PART_INFO_STRUCT_PTR host_entry /*[IN]/[OUT] the entry to read from disk */

)

............

_pmgr_disk_to_host(disk_entry + host_entry->SLOT - 1, host_entry);

if (host_entry->TYPE == 0 || host_entry->START_SECTOR == 0 || host_entry->LENGTH == 0)

{

error_code = PMGR_INVALID_PARTITION;

}

.........

}

Please folks worked on SD card example program please puit the lime light ,

could you please let me know what it the return error value?

when testing the example sdcard example from MQX V4.1 (the latest version) on your side, is this problem still remains?

another question: which board are you using?
