Obtaining the Firmware Build Version
There are three ways to obtain the firmware versions of the DA-66X-CE embedded computers.
This information is particularly important for identifying features.
y Examine the welcome message after you log on to the computer.
y Log on to the web-based management system (described in a later chapter) to view the system
information.
Memory and File Systems
The 128 MB of SDRAM space is divided into two main parts. The main memory, which houses
the operating system and user applications runs, has a capacity of about 112 MB. The kernel image
occupies the remainder of the memory space.
The internal file system in the DA-661/663/663-CE embedded computer controls access to the
ROM, and also provides file storage in the object store, which is in the RAM. The ROM file
system provides persistent storage for applications and their related data even when the main
power supply is lost. It integrates the read-only files that are stored in the Flash ROM with the
read/write files of both an application and a user. A child directory named “NORFlash” under the
root indicates available ROM storage of the flash memory of size about 15.5 MB.
The root directory is a RAM file system of size 15.5 MB. It can be used for storing temporary files
for your applications and data. However, do not place persistent files or applications in the root
directory, because they will be deleted when the system is shut down. Instead, place them in the
“NORFlash” directory.
