Hi William
[root@local xilinx_sysace]# cat /proc/partitions

I want to know wether the zeroes in the entry are due to problem in
flash file system format or due to the driver.
The zeros indicate there have been no I/O transactions. Can you write
to the device or partition it using fdisk? Any kernel messages after
loading the driver?
After doing some i/o transaction, i got the following output in
/proc/partitions. thanks william.

It looks fine now.
Am able to do fdisk and it shows the partition.
root@local xilinx_sysace]# fdisk /dev/xsysace
Command (m for help): p
Disk /dev/xsysace: 32 MB, 32112640 bytes
4 heads, 32 sectors/track, 490 cylinders
Units = cylinders of 128 * 512 = 65536 bytes
Device Boot Start End Blocks Id System
/dev/xsysace1 * 1 489 31280 4 FAT16 <32M
Command (m for help):q
root@local xilinx_sysace]#
As of now i am not able to mount the flash.
The flash is formatted to FAT16 in windows with only one partition.
Can i mount it in linux.?
Got this doubt after reading the article:
