One of the most important conference of the Embedded Linux community will take place at the end of this month in California: the Embedded Linux Conference will be held in San Jose from April, 29th to May, 1st, co-located with the Android Builders Summit. The schedule for both of these events has been published, and it is full of interesting talks on a wide range of embedded topics.
As usual, Bootlin will participate to this conference, but this participation will be the most important ever:
- No less than seven engineers from Bootlin will participate to the event, which is almost our entire engineering team: Alexandre Belloni, Maxime Ripard, Boris Brezillon, Antoine Ténart, Grégory Clement, Michael Opdenacker and Thomas Petazzoni. Only Ezequiel Garcia will be missing.
- Seven talks or BOFs from Bootlin engineers are part of the conference schedule:
If you are interested in embedded Linux, we highly advise you to attend this conference. And if you are interested in business or recruiting opportunities with Bootlin, it will also be the perfect time to meet us!
Late october will be a busy moment for all the embedded Linux developers meeting in Edinburgh, UK. The Linux Foundation is organizing a number of conferences here, including the Embedded Linux Conference Europe (October 24-25) and LinuxCon Europe (October 21-23), and many co-located other events.
Bootlin will be present at several of these events:
- First, three Bootlin engineers will be present at the ARM kernel summit on October 22nd and 23rd. The ARM kernel summit is an invitation-only conference, organized in relation with the Linux Kernel Summit. Gregory Clement, Maxime Ripard and Thomas Petazzoni, engineers at Bootlin have been invited due to their participation to the ARM support in the kernel, mainly on Allwinner SOCs for Maxime and on Marvell SOCs for Gregory and Thomas. Being present at this event is an excellent opportunity to be part of the discussion that shapes the future of ARM support in Linux, and strengthen our relations with other members of this growing community.
- Then, the entire technical team of Bootlin will attend the Embedded Linux Conference, on October 24th and 25th. Several talks will also be given by Bootlin engineers:
- On Thursday, 24th October at 11:40 AM, Thomas Petazzoni will give a talk titled Device Tree for dummies!, which will give an introduction to the Device Tree on ARM: what it is, how it is compiled, how it used by the kernel, how Device Tree bindings are defined, how drivers are affected by the Device Tree, etc.
- At the same time in another room, Michael Opdenacker will lead a Bird of a Feather session dedicated to Small Businesses in the embedded Linux world. Exchanging experiences, networking with other companies working in the same field, etc.
- Still on Thursday, at 3 PM, Gregory Clement will give a talk on the Linux kernel Common Clock Framework, which will be an updated version of the talk he gave at ELC earlier this year.
- On Friday, 25th October at 9:30 AM, Thomas Petazzoni will be part of the keynote panel session dedicated to a discussion on Embedded Linux build systems together with Tim Bird (Sony Mobile), Ross Burton (Intel), and Karim Yaghmour (Opersys), the panel being moderated by Jeff Osier-Mixon (Intel).
- On Saturday 26th and Sunday 27th October, the Buildroot community is organizing its traditional Developers Meeting, to which Thomas Petazzoni will participate. Some of the core Buildroot developers will join for two days of discussion and work to improve this embedded Linux build system.
As you can see, this will be a very interesting and busy week, and we’re all looking forward to meeting more embedded Linux developers and learning about the latest technologies in this field.

The success of the BeagleBoard platform, a low-cost development platform, that has greatly contributed to the success of Texas Instruments OMAP3 processor in the embedded Linux industry, seems to have inspired another processor manufacturer: ST Ericsson. They have recently unveiled Snowball, a low-cost development platform for their AP9500 processor, which features a dual Cortex A-9 ARM core and a Mali 400 GPU.
The development board is designed and produced by our partner Calao Systems, and offers the following features:
- The AP9500 processor, dual Cortex-A9 and Mali 400 GPU
- 4 to 8 GB of e-MMC storage
- 1 GB of LP-DDR2 RAM
- Micro-SD slot
- Ethernet connector, Wifi and Bluetooth
- HDMI output, composite video output
- Audio in/out
- USB On The Go
- Battery charger
- On-board battery to keep time
- Serial port connector, JTAG connector, MiPi 34 debug connector
- Builtin GPS
- 3-axis accelerometer, magnetometer and gyrometer, one pressure sensor
- Expansion connectors to access SPI, I2C, LCD, MiPi devices, GPIO, UART, etc.
- Last but not least, the board can be powered via USB (through a regular cable or through a Y one if power hungry devices like Wifi are used.)
The technical documentation page has a few more details, but at this time, they isn’t a lot of public information available about the AP9500 processor. I hope that ST Ericsson will fully understand how open source works and will soon release datasheets for the AP9500 in an open way. Interestingly, the AP9500 does not use the traditional PowerVR SGX 3D graphics core designed by Imagination Technologies and found in many other ARM processors, but instead uses the Mali graphics core, which is designed directly by ARM. It seems ARM has already open-sourced the kernel side bits of their graphic drivers, but it looks like a proprietary binary blob in userspace is still present.
The board will be available in two variants:
- A Product Development Kit variant for 241 Euros.
- A Software Development Kit variant for 165 Euros. My understanding is that the only difference between the two are the expansion connectors, present on the PDK variant but not on the SDK variant.
The board should be widely available at the end of Q2 2011, i.e around June, though at Bootlin, we will receive our first samples by the end of March thanks to our partnership with Calao Systems. The Snowball platform is supported by the Igloo Community, which hosts mailing-lists, an IRC channel, documentation and will also provide Meego and Android builds for the Snowball in the future.
Stay tuned on this blog. As soon as we get our own boards, we will write about our experiments with them.
Free seats to community contributors in our public embedded Linux training sessions
At Bootlin, we owe a lot to the Free Software community, and we’re doing our best to give back as much as we can.
For each of our public embedded Linux training sessions, we decided to offer a free seat to a deserving contributor to the community, with a commercial value of 1750 € (including materials, lunch and laptop rental).
