Preparation:
when I connect BeagleBone(Angstrom system) to computer, I can only find one partition /sdd mounted ( by command: fdisk -l ; dmesg | tail; and open computer file to see)
when I connect Fedora 17 SD card (which is not compatible for BeagleBone yet) to computer, I can find two partitions /sdb1 and /sdb2 mounted
So, I disconnect BeagleBone, and take the Angstrom SD card out, and directory connect to computer. Now, I can see two partitions /sdb1 and /sdb2.
when I use command: screen /dev/ttyUSB1 115200; to connect Angstrom on Beaglebone, it works. username: root, password: blank. exit by: ctrl a then ctrl z.
Run command: dmesg | grep FTDI | grep “now attached to” | tail -n 1 | awk ‘{ print $NF }’; to find out what /dev/ttyUSB# the BeagleBone is connected to. usually USB1
Release 0.1: Keep the partition 1 of Angstrom (boot files), and replace partition 2 with Fedora 17 userspace(“rootfs”).
Mount /dev/sdb2 and check files:
[root@Fedora17 jcqiu]# mkdir /mnt/AngRootfs
[root@Fedora17 jcqiu]# mount /dev/sdb2 /mnt/AngRootfs
[root@Fedora17 jcqiu]# ls /mnt/AngRootfs/
bin boot2 etc lib media opt proc sbin tmp var
boot dev home lost+found mnt p1 run sys usr
Delete all Angstrom root files:
[root@Fedora17 jcqiu]# rm -rf /mnt/AngRootfs/*
Download the F17 rootfs from: http://download.fedoraproject.org/pub/fedora-secondary/releases/17/Images/armhfp/Fedora-17-armhfp-console.tar.xz
yum install p7zip, and unzip the download file.
and then tar the file to /mnt/AngRootfs/
However, there is error when I tar the file:
[root@Fedora17 Downloads]# tar -xvzf ./Fedora-17-armhfp-console.tar /mnt/AngRootfs/
gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now
Find out I should not use -z here. Try again:
[root@Fedora17 Downloads]# tar -xvf Fedora-17-armhfp-console.tar /mnt/AngRootfs/
tar: /mnt/AngRootfs: Not found in archive
tar: Exiting with failure status due to previous errors
Find out use -C option to specify in which directory you want the files extracted.
[root@Fedora17 Downloads]# tar -xvf Fedora-17-armhfp-console.tar -C /mnt/AngRootfs/
Eject SD card: eject /dev/sdb;
put SD card back in BeagleBone, and connect to computer.
Nothing happen….
run command: dmesg | tail;

I will continue work on it.
