Dear all,
I am Linux driver programmer.
I have a FAT12 issue on my SD cards. I have got these addresses from the
fs-lists as the maintainer support mail IDs for FAT-FS.
I am using the 2.6.10 kernel, X86 like systems.
I am NOT able to mount the Camera formatted FAT12 filesystem on my linux
BOX. SD card is of size 16MB. At the same time I am able to mount the SD
cards formatted in windows & linux.
I have identified fat_fill_super() in fs/fat/inode.c file as the
function that reads the super block of as MS-DOS FS.
To debug, I have rebuilt my kernel 2.6.10 inserting some debug messages
in the FS sub-system to know what data is coming into "struct
fat_boot_sector *b" structure in fs/fat/inode.c file after sb_bread()
call.
I believe that this data in the "struct fat_boot_sector *b" should be
FAT12 information.
On the camera formatted SD that is NOT mounting I have found this
structure to be all '0' till total_sectors variable (relevant till here
on - FAT12).
Will you please verify if there & tell me if the problem is in the FAT
sub-system.
Regards,
Mukund Jampala
