I have not done it just copied from website. MAy be after some year will need MicroSD partitioning The bootable microSD currently provided by Acme with Debian preinstalled is organized in 4 partitions: Format type Label Size Mount point Description 1 FAT16 kernel 32MB /media/mmc_p1 Linux Kernel image and some optional file used by the bootloader at startup 2 EXT4 rootfs 800MB / Linux root filesystem 3 EXT4 data 800MB /media/data User data 4 SWAP swap 128MB Available for memory swap Brand new microSDs tipically are formatted with a unique big FAT partition so the operation to do are: * Delete the factory default big FAT partition * Create the four partition requested by the FOX Board G20 * Copy the file inside the new partitions -------------------------------------------------------------------------------------------------- microSD to tar file copy This method is useful if you want to have a snapshot of your microSD contents on your hard disk to use as master to create new copy. Insert the master microSD in your Linux PC. Three new folders will appear on your desktop: * kernel * rootfs * data Open a terminal session and type: $ cd /media/kernel $ sudo tar cvjSf ../kernel.tar.bz2 . ... $ cd /media/rootfs $ sudo tar cvjSf ../rootfs.tar.bz2 . ... $ cd /media/data $ sudo tar cvjSf ../data.tar.bz2 . ... The option meanings are: * -c create a new archive * -v verbosely list files processed * -j filter the archive through bzip2 * -S handle sparse files efficiently * -f use archive file or device ARCHIVE On the /media directory will appear the new three tarbal files: * kernel.tar.bz2 * rootfs.tar.bz2 * data.tar.bz2 usable as master for the microSD clone. tar file to microSD copy Partition and format a new microSD following the instruction on this article: How to create a bootable microSD. Be sure that the three new partitions are mounted and visible: $ ls -al /media total 170120 drwxr-xr-x 5 root root 4096 2011-08-16 12:23 . drwxr-xr-x 22 root root 4096 2011-08-16 09:12 .. drwxr-xr-x 3 root root 4096 2011-07-13 18:08 data -rw-r--r-- 1 root root 137 2011-08-16 12:23 data.tar.bz2 drwx------ 2 root root 16384 1970-01-01 01:00 kernel -rw-r--r-- 1 root root 1797040 2011-08-16 12:05 kernel.tar.bz2 drwxr-xr-x 21 root root 4096 2010-09-22 16:17 rootfs -rw-r--r-- 1 root root 172364479 2011-08-16 12:09 rootfs.tar.bz2 Be sure that kernel, rootfs and data are directory and not files.
