Hi All,
I am having experience in Omap, imx based linux platforms. How shall I involve myself into the linaro development, I am into this maillist and using the linaro distribution into beagle board, since all the participants are having linaro mail ids, Kindly advise me and use me as a resource for this development.

Thanks a lot for the offer! We don't have a very good list of things that people can grab, but since you mention you have a beagleboard, there are various things which could be done on top.
- testing our linux-linaro-2.6.35 kernel and u-boot-linaro bootloader and reporting any missing features / bugs when compared to other distros - measuring boot time of the various pieces (x-loader, u-boot, kernel, userspace) perhaps breaking each piece open and seeing where time is spent in the kernel init; how does NAND boot versus MMC boot compare with your MMC? - creating a barebox package building a beagleboard version; does it have regression over u-boot? (perhaps some fixes which went into u-boot are missing?) - trying to run MeeGo on top of Linaro - packaging linaro-media-create and other scripts into a linaro-media-utils package or something similar - insert your own idea here! You might be more of a toolchain person, or a graphical applications specialist etc. etc.
(#linaro if you need some guidance/tips on the above ideas, or followup here)
Cheers,

Note that just testing things "as they are" might not give the fanciest results :-)
For example, we have an i.MX35 @ 532 MHz booting from NAND, and it takes 336 ms from the first user-changable assembler instruction (after the ROM bootloader) up to /sbin/init is started (we toggle a GPIO in both places). However, achieving that needed some funny parallelization hacks in Barebox, plus a creative block size of the Linux kernel.
If you configure it with the off-the-shelf configuration, it will surely need longer.
- creating a barebox package building a beagleboard version; does it have regression over u-boot? (perhaps some fixes which went into u-boot are missing?)
Note that Michael Grzeschik mgr@pengutronix.de recently worked on bringing Barebox support for the beagle board up to date, the results didn't hit the Barebox mainline yet. We are working on a step-by-step documentation for the elinux.org wiki.

- trying to run MeeGo on top of Linaro
This is interesting, I'd like to do this too. What does this comprise? Do I just take the Linaro kernel (linux-linaro-2.6.35 kernel and u-boot-linaro bootloader) and try to install the packaging system / operating system from MeeGo on top of that?

There is an ongoing effort to produce a proof of concept Linaro+MeeGo image. For more information see:
http://wiki.linaro.org/Platform/UserPlatforms/Heads/Meego
and pop into the #linaro channel on freenode, Alexander Sack (asac) is the lead for the team who are looking into this.

Hi, Thanks for allowing me to start my contributions. I have downloaded 23/08/10 daily packages and put the binaries into MMC and boot the system. It was hanging in the U-Boot after I2C ready console print.
My beagle board is Rev C4.
Thanks, Hariharan.V.

Could you try holding down the USER and RESET white switches together? They are next to the EHCI USB port. That should force the board to boot from MMC.

Common problem with upgrading to X-loader 1.4.4ss and u-boot 2010-03+
Your board has an older X-loader installed (factory 1.4.2 probally), with MLO and u-boot.bin on the fat partition you need to hold down the user button to get to u-boot prompt.. Once there reflash the MLO and u-boot.bin..
