Does someone wants Tizen development platform device?

Half year ago I got Tizen development platform device. Played a bit with it and then put in a drawer due to other things to do.

Today I looked again at Tizen. Nothing changed. Git repositories still scream “****@#$!$ *** *** you developers!” due to lack of any commits other than code drop bombs.

So if someone (from Europe) wants this device — be first to comment. Sending with DHL and you pay for posting.

Tizen: first impressions

During my stay in Oakland, CA (due to Ubuntu Developer Summit) I decided to attend also Tizen Developers Conference. Not that I have any relations with this platform — just wanted to meet some friends from Maemo times. And I did not had plans for Tuesday evening while Tizen visitors had social event planned in The California Academy of Sciences.

For those which do not know what Tizen is a bit of history. Years ago Nokia made few internet tablet devices (770, n800, n810) and phone (n900) which were running Linux distribution named Maemo. It was loosely based on Debian. In meantime Intel created Moblin which was their distribution for mobile devices. Few years passed and they joined forces and MeeGo was born. Nokia released N9 phone with it, ASUS had netbook running MeeGo and maybe few other devices appeared on market. Then history repeated: MeeGo merged with LiMo and they created Tizen project.

It is hard to tell was conference success or not because I did not attended any sessions there — just opening keynote by Jim Zemlin. On first day I also came for technical showcase and partner demos. But they were squeezed in very small room so it was hard to discuss with people showing their work. Maybe next time organizers will give at least 4m² per demo — this should be a minimum.

But today I got Tizen Developer Platform device and thumbdrive with SDK on it. So decided to play a bit with it. It was not enjoyable experience.

First ugly part was Tizen SDK “so-called” installer. 823MB shell script… I thought that those times passed long time ago. Anyway tried to run it. All I got was message that 64bits systems are not supported. Good to know that, but my x86-64 systems are able to run x86 binaries without problems. Ok, I made workaround and then got message about missing qemu, rpm, libsdl packages. No, I will not install rpm on my Ubuntu systems.

So I decided to cut that crappy shell script and take a look at tarball. Fast “tail -n+122 tizen-sdk-0423.bin >tizen-sdk.tar.gz” and I was able to extract SDK. Got 26 zip archives.

One of them contains rootfs created from packages based on Debian/Ubuntu packages. Some are from times when dinosaurs ruled the Earth (debianutils 2.17 was released in 2006), some are more fresh (like gcc-4.5 based on version from May 2011). In other words tradition started by Maemo is continued in Tizen and developers are given mix of fresh tools with long time forgotten ones. And Scratchbox 2.

To connect with device there is “sdb” tool. It introduces itself as “Smart Development Bridge” but in past it was named “Samsung Development Bridge” (run ‘strings’ on binary). And it’s father has a name “Android Development Bridge” and has some more options.

Anyway if you want to connect to device then few steps are required:

  1. On device go to settings and set USB to ‘USB debugging’ mode. This will switch it into cdc_ether gadget.
  2. On host do “sudo ifconfig usb0 192.168.129.1″ to configure networking.
  3. Connect to device: “ssh root@192.168.129.3″

And then you can enjoy system which is a mixture of few Debian/Ubuntu versions. And forget about updates — unless you know how to get to 165.213.180.233 and know password of “kb0929.kim” user there (taken from /etc/apt/sources.list file).

Device uses Linux 2.6.36 kernel with unknown patches on top including CMA and Android ones. Quite old one but works. Hope to get newer one from someone.

What I do not like is availability of sources. There is review.tizen.org website with git repositories but I want to vomit when I see commits like “let’s add 2.6.36 kernel in one commit”. Lovely lack of ideas how to help developers.

What I will do with device? Not decided yet. Waiting for instructions how to get into bootloader to boot own kernels. Then who knows… replacing Tizen with Android or Ubuntu?

UDS-Q

Another May, another Ubuntu Developers Summit. This time I am in Oakland, California, USA (even if my tweets shows Dallas, Texas as geolocation).

As usual with US trips this one took insane amount of time. But I was 3cm from not going here… Why? Because I got stuck in toilet at home. Hopefully with help from neighbour I was able to bash door out and get to the bus stop on time.

Then standard set of bus, plane, plane, train and finally arrived in hotel. As my room was not yet ready I got 30$ coupon to bar to not waste time on waiting. Free meal/beer ;)

My room is at 17th floor (which means 15th) and has a nice view in the evening:

On Sunday I went to see San Francisco centre (I saw Golden Gate on earlier visit). Chinatown was interesting experience. Lot of people speaking language which I do not understand, shops full of food which I do not recognize.

Some random photos:

After getting some souvenirs and refilling of my US T-Mobile sim card I decided to go to the cinema for ‘The Avengers’ movie. It was nice experience. Touchscreen operated ticket machines which allow to buy ticket in one minute (but people were standing in long queue to buy tickets in ‘normal way’) made it even better. As in Poland there was big amount of commercials before movie (including some in style “our Army/Navy is great, why not join us”) but what I liked was just-before-movie animation reminding about not talking/texting/tweeting during movie (made with characters from “Madagaskar” series). Have to admit that RealD 3D glasses were more comfortable than Dolby 3D ones used by Polish cinemas. Movie itself was great but I think that will have to see it in Poland due to my English ;D

During evening there was usual Canonical internal plenary and then dinner. I even managed to sleep 6 hours despite jet lag ;D

Monday started with interesting keynote and presentation of Calxeda ARM server using technology they were talking about at previous UDS. Photos:

It is 2U case with 24 Serial-ATA discs and 12 nodes with 4 quad-core EnergyCore processors per node. The only cables inside are power ones as rest of connections is on pcb. Connection with world by four Ethernet connectors.

I went to “Create filesystems for embedded devices” session where we discussed how to make Ubuntu Core even smaller. People mentioned OpenEmbedded, OpenWRT, buildroot as usual, we got some strange use cases too. What will come from it? Time will show.

Plenaries were interesting. First Chris Kenyon told about cooperation with OEMs and ODMs and how it relates with Ubuntu. Laptop in a pizza box picture was nice — reminded developer boards. Then Bdale Garbee from HP shown us that there is no way to go though life without being served by HP technologies or hardware. Both talks were great and I hope that rest of plenaries will be like that.

After plenaries I went to San Francisco to register at Tizen conference and to meet some friends from Maemo times. Technical showcase and partner demos were boring and it was hard to feel that it is something innovative. But who knows… maybe Tizen will be yet another phone/tablet/ivi/etc OS even when Moblin, Maemo, MeeGo did not succeed.

During evening (back at UDS) there was ‘Meet & greet” social event. Our Linaro group (Amber, Ricardo, Paul, me) was showing member boards and replying to misc questions from audience.

What next? Sessions, social events, discussions about my patches with other developers, some sight-seeing.
