+==== Handle Read-only File System====
-When the BeagleBone Blue Board is used the first time (never used with EEROS before or a brand new BeagleBone Blue / Image), some initial setup steps are needed. The script **deploy.sh** will copy the executable and libraries to **/opt/eeros**. Therefore, this folder must be present on the target or the copy fails. To create the folder, execute the following on the BeagleBone:
+Our images for the board come in two flavors, development and release. The release image is write protected which makes it safe for powering it off without proper shutdown procedure. However, when deploying to such an image, you will get
 <code>
-debian@beaglebone:$ sudo mkdir /opt/eeros
+$ scp: /home/ost/bin/delta: Read-only file system
-debian@beaglebone:$ sudo chown debian:debian /opt/eeros/
 </code>
+Before downloading you have to make the file system writable. Connect to your target with
-Also, some links must be created. The system must find the eeros libraries to load them. The following symbolic links are needed:
+<code>
+$ ssh ost@192.168.7.2
+</code>
+then remount the file system with
+<code>
+ost@bblue:$ sudo mount / -o remount,rw
+</code>
+A system which is longer read-only should be stopped gracefully at the end with
 <code>
-debian@beaglebone:$ cd /usr/lib/
+ost@bblue:$ sudo /sbin/halt
-debian@beaglebone:$ sudo ln -s /opt/eeros/lib/libbbblueeeros.so.1.2.0.0 libbbblueeeros.so.1.2.0.0
-debian@beaglebone:$ sudo ln -s libbbblueeeros.so.1.2.0.0 libbbblueeeros.so

-debian@beaglebone:$ sudo ln -s libeeros.so.1.1.0.0 libeeros.so
 </code>
-Make sure the version information (....so.1.1.0.0) is not outdated! This can be checked by browsing the **BeagleBoneBlue/install-armhf/lib/** folder on the development computer before copying the libraries to the target.
