PandaBoard.org and Early Adopter Program

Today it was finally released the new PandaBoard website, showing everything you wanted to know about the new community oriented OMAP 4 board.

If you are already used with BeagleBoard, Panda should be similar in some way, but now deploying the latest OMAP 4 SoC and tons of new stuff.

What you can find at the PandaBoard:
– Dual Core ARM Cortex™ A9 powered by OMAP4430
– 1GB LPDDR2 SDRAM
– PowerVR SGX 2D/3D Graphic Accelerator
– WLAN, BT and FM by WL1271
– DVI-D and HDMI support
– 2x USB Host + Ethernet by LAN 9514
– Mini USB with OTG support
– SD/MMC
– JTAG
– RS-232 UART
– LCD and Generic Expansion and more

Software Support:

Another good thing is that much of the software support is already available at omapzoom, like Kernel, X-Loader and U-Boot. Upstream kernel is still missing some patches, but there’s a lot of work going on linux-omap, so expect at least basic support from upstream soon. For bootloader you can already use U-Boot from upstream, as Sakoman did an awesome work doing the Pandaboard and OMAP 4 support.

Early Adopter Program:

While PandaBoard is still not out for general public you can already participate at the Early Adopter Program and luckly get a board for free (and first than everyone else)! All you need to do is go to http://www.omappedia.org/wiki/PandaBoard_Early_Adopter_Program and propose a cool open source project that could take use of it. The board is really small and powerful, think about running Ubuntu, MeeGo or any other distro and getting 3D support, 1080p video decode and more! Lots of ideas, for sure.

If you’re interested don’t waste your time and join the still small PandaBoard community, joining the mailing list and IRC channel #pandaboard at FreeNode.

Happy hacking!

Ubuntu Maverick on ARM (Beta Released!)

2010-09-08 18:11 UTC  by  rsalveti

For Maverick Meerkat we’re continuing improving the ARM support for Ubuntu. With Lucid we got the first release optimized for ARMv7 (Thumb2 and SoftFP but not NEON), and for Maverick the plan is to keep the same ARM optimizations as base, but improving board support and user experience.

Currently the main target boards are the ones based on OMAP 3 and OMAP 4, like:
BeagleBoard (C4 preferred)
BeagleBoard xM
PandaBoard (still to be released)

The main decisions to support these boards are basically the upstream support, solid community around them, easy hardware access and CPU power (standard Ubuntu is quite heavy, so we need a good and powerful machine).

At the moment we already got a good support for them, and the Beta release is somehow usable already! There are some development on-going to have a full working 3D interface (unity) for OpenGL ES much the same way we have for normal OpenGL devices. The only bad thing is that currently most of the 3D drivers for ARM (if not all) are closed source, so the development is a little bit harder than the usual.

If you just got your BeagleBoard xM, or want to try Ubuntu on your C4, please give it a try. For Maverick the idea is to give the users a pre-installed image, that you just need to ‘dd’ to your SD card, boot and adjust the environment.

Here are the instructions needed to get Ubuntu up and running at your OMAP device: https://wiki.ubuntu.com/ARM/OMAPMaverickInstall

In case you don’t have any of these boards, but want to use Ubuntu with different devices remember you can always try to build a ‘rootfs’ with RootStock. You’ll only need a working and compatible kernel and boot-loader.

And please, in case of you find any bug, want to help testing and getting Ubuntu better on your ARM device, just poke us at #ubuntu-arm (freenode). We’ll for sure be happy to assist you with any problems you may find.

Note for Beagle xM users: in case you find that your Maverick Beta image doesn’t boot with your board, please check bug https://bugs.launchpad.net/bugs/628243. This means that you have a Numonyx memory chip, and unfortunately the fix didn’t make Beta. To work around it just mount the first partition of your SD card (after giving ‘dd’) and replace your MLO with http://people.canonical.com/~rsalveti/maverick/boot/xM/MLO. After this just umount the partition, put it at your board and boot it.

New Job

It’s been a while since I don’t post anything, and the main reason is that I just got a new job and I’ve being pretty busy with it :-)

After working at INdT for more than 2 years, I decided that it was time to move on, get back to Campinas, get closer with friends and family and start looking for a new job.

I had a quite good time at Recife, working with Mamona, Maemo and MeeGo, mostly helping bring up different ARM platforms to be used by the Institute in many different projects. The work was nice, but Recife can be hard to get through over the time. I’ll for sure miss the nice work place we’ve built, and the nice people I worked with.

About the new job, I’m quite happy to announce that I’m now working as a Software Engineer at Canonical. My main objective now is to help bringing Ubuntu into different ARM platforms, like beagleboard and the new pandaboard.

Canonical is awesome, and the people from the Ubuntu Platform Team is even greater. Had the opportunity to meet most of the people at the last Ubuntu Platform Sprint that was held at Prague, and it was awesome to see so many skilled and fun guys working together to improve Ubuntu.

That’s it, now it’s time to get back to work because we have a huge pile of cool and fun things to work on :-) If you’re interested in understading, helping and participating on what we’re currently doing, get at #ubuntu-arm, freenode, and ping me (rsalveti)!

Greetings!

It’s been a long time since we released 0.1 (at that time I wasn’t even working at INdT),
so is with pleasure that I’m announcing the official Mamona 0.2-Beta release.

A lot changed since 0.1, we had a couple of goals for 0.2 release, mainly to support
Nokia N770 and to add some highly missing features, like network and virtual keyboard.

Main features already available for the beta release:

  • Glibc – 2.5
  • GCC – 4.1.2
  • Full Python 2.5 support
  • Enlightenment Window Manager
  • USB Networking
  • Bluetooth support
  • Noemu Packages
  • Mamona SDK
  • QEMU (user mode emulation) 0.9.0 for Mamona SDK

Mamona with virtual keyboard at N770

These latest weeks we’ve been working to get the virtual keyboard on Mamona. We first studied Hildon Input Method and it’s framework, but it was not exactly what we wanted.

After researching a little more, with suggestion of trickie, we decided to try matchbox-keyboard, and realized that it was almost what we wanted, it’s simple, fast and doesn’t depend on any toolkit.

Then, we got to a final solution, that’s to let matchbox-keyboard working with enlightenment, and with the same behavior as maemo with hildon-input-method.

Here it’s a demo of what you get if you build the latest version of mamona (running on N770 :-):

How to get to this:
Patches on matchbox-keyboard, mostly by Aloisio;
Enlightenment Patches, also by Aloisio;
Mamona Input Methods that works with ecore and gtk;
Mamona-IM Enlightenment Applet

We’re still working on to get matchbox-keyboard patches upstream, but, if you need them, you can get at mamona git repository.

Please, use it and test if everything is working fine, or at least as expected :-). In case you want to report any bug, please open a ticket at mamona’s trac and we’ll work on it as fast as we can :-).

Thanks Aloisio for working with Matchbox-Keyboard and Enlightenment, Lauro for working on the first draft of mamona-input-methods and Tiago Buarque for the applet icons!

Now that I’m currently working with OpenEmbedded at Mamona, I often have to edit and create new ‘bb’ files (the definition and instructions to build packages or define configurations, like ebuilds for Gentoo).

After working with ebuilds to build a few packages, I was really comfortable with the syntax highlighting and new ebuild templates that I have with Vim, but didn’t found anything like that for Bitbake and OpenEmbedded.

First searching for syntax highlighting for Bitbake, I found that Chris Larson already created a Vim syntax file that covered almost everything I need, but was a little bit different from what we have with ebuilds, so I decided to create my own syntax (based on Chris’) and template plugin.

Here’s the code, I just released the version 0.1, it’s quite easy to install, just like any other vim syntax and plugins, just copy the directories at your ~/.vim (sorry emacs users, but this is only for Vim ;-)

I’m probably not covering everything from the OpenEmbedded/Bitbake syntax, but it’s quite good for now. If you see any red text around at your code just email me and I’ll try to fix it (patches are also welcome).

It was quite fun to develop for Vim, it’s not that different from any other language and it has many good help files where you can find every allowed syntax that you can use in your script.

Here are some screenshots from bb files and the template plugin:

* Syntax Highlighting:
vim syntax

* Template for new bb files (just open a new file that ends with ‘.bb’):
vim template
The template plugin will try to find your user name and email by your global git conf.

Thanks Chris for his syntax file and for the gentoo developers, who created the gentoo-syntax package.
