RE: [ECOS]- fat file system (dosfs)

["Alok Singh" <aloks@broadcom.com>]

Sergei,
I need to create the partition under ecos only. I've to support
fatfs(creation, read and write) on the flash device. My boot-loader too
only supports read of fatfs. So I need to do it from my ecos
application. 
Nevertheless, the information provided by you is quite useful for me.

regards,
Alok

If you didn't mean to create it under eCos..., you can use Linux as well

32 Mb ms-dos disk

1) dd if=/dev/zero of=/tmp/msdos count=64k 	;# 512x64k room
2) mkfs.msdos /tmp/msdos, or mkmsdos /tmp/msdos ;# create ms-dos fs
3) mount /tmp/msdos /mnt/disk -oloop,rw 	;# mount, do it as root

I think that using `mtools', you can mformat it, mcopy files there, etc.
