Hello All,


      We are working on I.mx233 processor with free scale provided BSP, As per the current requirement once O.S is come up in the device , If any Update is available (New Firmaware is stored in SD card)  , then we have copy boot loader and O.S to nand flash. But We are unable to access Flash Media Driver Functions "FMD_Init / FMD_Read"  which is implemented in the

".....\COMMON_FSL_V2_PDK1_8\NAND\FMDCOMMON\BIG_SECTOR_INTERLEAVE\fmd.cpp" . If we use this function  in one of the driver , It throws

"LNK2019: unresolved external symbol FMD_Init...." .


How to access Flash Media Driver Functions in other driver ...?

How to access particular sector in the nand flash          ...?


Please any one help me sort out this issue.
