Hi All, I am working on integrating the mmc driver on Linux and when I try to mount the device I always get the error "mounting /dev/mmc on m failed: Invalid argument" . I also see that when ever I try to mount,the drivers request function is invoked to read the first sector(MBR).Thus the driver always reads the MBR and returns to the filesystem.The moment I load the driver the drivers request function is invoked to read the first 8 sectors.The data for the block0 is as follows .The rest blocks are all 0. 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000004bc1f59e00 033d061cfcd9f90007531e000000000000000000000000000000000000000000000000055aa. Interpreting the above data I could see that the volumeID is present at the sector location 0x000000f9. After giving this information I feel the file system should interpret the MBR's partition table and issue request with the calculated sector address. he following are the instructions I have followed to mount the module. mknode /dev/mmc b 254 0. mount -t vfat /dev/mmc /mmc.(invalid argument) When ever I do the mount I could see the drivers request function is invoked to read the first sector(sector 0).What should I do to make the file system read the volume ID (0x00000f9) sector. Can any one help me in debugging this issue.
