First you have to define "Linux" because there are MANY different variants of Linux. QNX, uItron, open source, etc., etc., etc., On embedded hardware most silicon vendors provide a BSP (board support package) with drivers for their silicon on recent Linux kernel releases, and we've noticed that even though Android is gaining momentum, its still too "handset oriented" for embedded applications. Really if you don't have a GUI, you don't need Android because there is a more code out their for Linux and associated drivers. Really, until all the silicon vendors out there start releasing Android BSP's, its not worth the effort (and nobody wants to pay the NRE) to deploy with Android.

Why not? What is preventing the independent developer community taking full advantage of the
platform? Well, that could be a rather long list, but I am going to single out one very basic issue
– lack of a proper open hardware/open software development vehicle, that is, reference
hardware with a relevant processor, and of course… a MODEM!
We have seen that the best way to engage with independent developers has been through a
truly open hardware platform like the BeagleBoard, where the data sheet is not secret and the
base port is available in source code form. This had to be the starting point if we were going to
do something about modems. Having a truly open modem is still a step further; the cost of
development of the stack, including the conformance and safe for network testing makes it
nearly impossible for the weekend enthusiast. Don’t despair though, there are solutions other
than porting Symbian to the HTC ADP1 or the Nokia N900… off-the-shelf GSM/UMTS modules.
An Introduction to the Symbian System Model
My partner local German partner developed an adapter board for the 3G modem listed here on
my website here http://www.gsm-modem.de/umts-module.html . We used the Telit UC864-G.
The adapter is designed for UC864-G (3G), GC864 (2G) and for CC864 (CDMA).
On iX-day (2th. June 2010 in Stuttgart Germany) I will present it. The speech listed on my
homepage http://www.gsm-modem.de :
“Open Source in M2M. Examples with Linux, Symbian and 3G Modem”
My offer to M2M developers: Ask for personal meeting or copy of the speech in English or
German language by email now.
The BeagleBoard is open source and supports the operating systems as blow:
- Ångström Distribution
- QNX Neutrino
- ARM Linux Internet Platform
- Windows Embedded from TI BSP
The operating system of Nokia phones will move to wireless M2M. I will keep the community posted.
How many of you have strived to put android programming in your resumes? I am sure, a lot of you. If not, then my friends, I should say it’s high time; every programmer should start playing with android. If you’ve read programming blogs before, you’ll understand the term ‘playing’. In a programmer’s world, you can only play on open source platforms; this is one of the key reasons why android is one of the largest growing markets in the industry. Vital it is, that Android had 26% of the total users, beating I-phone for the first time, in the month of November, 2010. The stats come in the courtesy of comScore MobiLens. This number of users tells us about the intensity of application development in this field. All of the progress invites data theft, as more and more business purpose applications are being run on android. This data-theft can be strongly reduced by Android’s powerful connection with VPN. So, if you’re an android user, let Pure VPN help you coming up with the best VPN Android connection for your android sets.
