*******************************************************************************
*           Release Notes for EB07 software update package V2.00r0            *
*******************************************************************************

The current eb07 updaer package includes new components which provide various 
new features. This document describes the most importand changes compared to the 
last release of the eb07 updater (old release: V1.18r3)

========
CAUTION:
========
When updating a eb07 containing a older firmware make sure to update all 
components (see config.ttl). This is the default configuration of this updater 
package. 

As soon as the new components provided by this updater package are installed on 
the eb07, all former versions of the eb07 updater package will fail when trying to
install a older version of the eb07 firmware. 

If for any reason a downgrade of a eb07 from the new firmware to an older version
is required, please contact STW for assistance. A new updater package containing 
the old firmaware is required. This package has not been released yet. 



Kernel
======
Formerly, Linux kernel v2.6.27 was used. Now we upgraded to kernel v3.4.17-rt28
(STW-V1.02r1). The new kernel is full preemptible (using RT_PREEMPT patch). 


Rootfs
======
The root file system format changed from ext2 to ubifs. This format can not only
be mounted read-only but also read-write. The default mounting configuration still
is read-only. It is strongly recommended to keep this configuration for a 
production system. 
However, adding additional programs or data to the rootfs or changing configuration 
files is much easier then with the ext2 file system. The ubifs can be remounted as 
a read-write file system from user space:
# mount -n -o remount,rw /
Now the root file system is writeable. Files can be added / changed directly on 
the target. To remount it read-only again:
# mount -n -o remount,ro /


UBoot
=====
The UBoot provides a new Update mechanism. With this it is possible to update the 
eb07 firmware via  the internal data flash or a USB flash disk. See EB07 help file
for more information.
