Recently Opened Hand announced Poky Linux for embedded devices. Currently the system runs on various Sharp Zaurus devices and there is also experimental support for Nokia N800 and OpenMoko Neo1973 devices. I tried the Poky system on qemu and also installed it on my Nokia N800.
The system contains UI component called Sato, which is corresponding component to the Hildon widget set. The system is fully open, and contains currently basic applications such as web browser and video player, a PIM suite called pimlico and some games.
Here's a capture of Poky Linux running in qemu:
And the system running on Nokia N800:
Seems that network is not supported yet on N800 so I was not able to test the browser any better. But currently the Poky Linux seems a promising option.

Lost in Berlin
On last week I was visiting Berlin. I took my Nokia N800 and a GPS receiver with me. I have installed Maemo Mapper on the device and loaded Berlin maps beforehand on it. Navigating was working nice, but I still had to buy a paper map. There's something that a digital map can't replace.
Another reason for taking the N800 with me was the WLAN connection. I succesfully connected to the hotel's WLAN. Also it was handy on the airport where I had to spend several hours. However the WLAN spots were not free so it cost some money but I can manage a few euro's cost.
I also finally ordered the Neo1973 (OpenMoko) device. I'll be waiting for it, and I will surely report first impressions on this blog. But until that I'm testing the development tools and tell more about them later...

OpenMoko finally here
So they really got first developer versions of OpenMoko device Neo1973 for sale. I'm about to purchase one of these very soon.
After reading specs and documentation I found this device even more better. The developer version of Neo1973 will include:
While waiting for the device I've been playing with OpenMoko system in QEMU. It seems quite slowish but can't yet say anything about the speed on the device. Here's a little video capture (sorry about the wrong aspect ratio):
So now waiting for getting the device on my hands to be able to tell more about it...
P.S. Nokia N800 got updated software and is running now Skype. Works fine but unfortunately it's closed software. However nice move...

GPL version 3
Recently Free Software Foundation released the final GNU General Public License version 3. What that does really mean?
First of all many software says it uses version 2 or NEWER. The key word is the later one because user may choose which version to use. Is there going to be two branches of one software, one for version 2 and one for the 3rd one? Ok, that might be a problem. However there's still some software which insist to use version 2 only. On of these are the Linux kernel. It will be version 2 unless something else is decided...
Also version 3 defines that some vendors can't any more lock their devices to use only the official binary provided by them. Vendors must now allow customized code to be flashed or uploaded to the device and not to lock it on any way. Sounds fair.
Secondly software patents are not allowed. This prevents deals which Microsoft has made lately with some Linux providers. It will be interesting to see the real affect. For now on we must only speculate.
Generally the GPL version 3 is good thing, but people should take a little bit careful with it at first. The future will tell what comes.
P.S. First developer versions of OpenMoko based phone Neo1973 will be available since 9th of July. I'll be waiting for it...

Long time indeed
First I must apologize for not writing for a long time, but have been busy and doing everything more important. And it's been silent lately.
Fortunately now the phase 1 of OpenMoko based phone Neo1973 is near. It's means that some devices will be available for developers to order. I try to be one of those lycky ones, but let's see first how many of these devices they're able to get for sale. Hopefully enough.
Meanwhile I got Nokia N800 (for the discounted price, thanks goes for Nokia) and had some time to play with it. It's quite impressive and a real improvement from 770. Now there's enough memory and CPU seems fast enough. It makes a really good tool with GPS receiver and Maemo mapper. Used it a few times to navigate while being at a car. And the media player is also a good piece of software, for example I tried playing music over UPnP from a friend's Windows XP Media center edition and it did a nice job. But again I have had a very little time to play with it more and implementing my own stuff for it.
Hopefully I have more time in future to update this blog but until then it's a bye.

The new mobile devices
Recently Apple announced the brand new iPhone. It sounds good: music device, phone and internet in same package. But wait a minute, isn't it just another phone? It has only a nice user interface and there's a new way to control the phone. And one thing I miss: iPhone is just an ordinary GSM phone. I'd like to browse the internet with high speed 3G connection, but no. And why to integrate big music player on it? I have already iPod, and my current phone has 1 GB memory card, audio player and internet access, and it supports 3G. Listening music with phone is not anything new. So the iPhone is just about a new UI design and controls? The worst part is that Apple don't want 3rd party applications for it. Yes, I can't develop any applications on it, and no way to get my favourite applications on it. It just is not open.
But lets take a look for a open phone. There's an option called OpenMoko. It's quite open, it has finger controllable touch screen, it also includes stylus for more accurate control, and the user interface looks also nice. It's based on Linux and open source software. It includes the basic operations (call, send & receive message) and allows installation of 3rd party applications. The first model, Neo1973, has quite nice touch screen (2.8"), built-in GPS and USB. However it's still GSM phone, no 3G. But sounds very nice. Unfortunately there's very little information about the platform. Is it based on Qt or GTK+ or is there some other widget set in use? Sounds like it's Debian-based, the provided presentation used apt-get. The phone is about to be on sale soon. Then we'll know better. But at least I'm excited.
Also Nokia published new internet tablet, N800, which is follower for the 770 tablet. It has improvements such like more memory, better CPU and camera. Sounds nice. It has active developer community and provides maemo platform and SDK for developing applications for the tablets. It has intenet (video) calls via VOIP (Google Talk). However it has no GSM phone at all. You still have to carry around a ordinary phone, preferably with bluetooh and fast 3G. It's kind of benefit also. You can update your phone from GSM to 3G and the internet tablet has also the speed benefit. However, the N800 is a good improvement - and it's open, at least on some level.

Playing around with a embedded box
Sorry, it's time since I last updated this blog but I've been busy with work projects. However I have had some time to play around with a nice embedded device on my spare time. I needed a wireless router so I bought a Linksys WRT54GL. It's originally a WLAN router with 200 MHz mips CPU, 16 MB RAM and 4 MB flash, with Linux based firmware.
There's lot of projects to replace the firmware, such as DD-WRT, OpenWRT and HyperWRT. I choosed to flash the DD-WRT to my box. Flashing went fine. After the flash I was able to access the router by telnet and HTTP. It was easy to set up SSH running from the web interface. So I had a Linux system running with SSH access on a embedded box. The next step was to install own software on it. I set up JFFS on the box and Samba share on a bigger server which was mounted by DD-WRT.
Next step was to install some packages with ipkg. I took the prebuilt packages from OpenWRT repositories. There was some problems installing some libraries because a Samba share does not support symbolic links. Solution is to make the proper links on the server side. It required some tweak to make the applications to run, such as set LD_LIBRARY_PATH to proper location. Some applications required some extra parameters to work properly. Generally the Samba share provided virtually unlimited amount of storage for applications. The only limitation is the box itself.
I'd like to set up a compiler environment for my desktop environment to build applications for mips and to run them on my WRT box. I have some ideas to make it run different kind of applications. However first I'd like to set up a web server on it and make my primary router to forward them to the WRT box. Which one would hit first, the power or the memory limit? How about to set up a swap over the Samba share? To be seen...
