Re: boot armv7 on qemu-linaro
Hi, I've used this script (http://wiki.gumstix.org/index.php?title=Overo_qemu_script) to package binary bootloaders, kernels and a rootfs into a qemu-bootable format. I tweaked it specifically for the Cortex-A8 based Gumstix Overo but it should also work for Beagleboard and should be a good starting point for other system.

Try interrupting u-boot on boot and typing 'setenv console ttyO2,115200n8' then 'boot' A 'saveenv' would normally make this permanent but I suspect this will fail on qemu (nand flash emulation?) so a boot.scr could do the trick. -Ash On Thu, Jan 12, 2012 at 11:20 AM, Andrei Gherzan wrote: > No quiet in it but console is ttyS2. > > On Jan 12, 2012 7:05 PM, "Ash Charles" wrote: >> >> On Thu, Jan 12, 2012 at 8:30 AM, Andrei Gherzan wrote: >> > Does anybody know why these boot messages are not printed on serial in >> > qemu? >> What are the kernel boot parameters?

Re: Kernel panicking with ALIP and NANO, 12.xx prebuilt images
Yeah---I'm also seeing this on Overo. I'm confused as to what exactly is causing the kernel panic but I suspect something in user space that is exercising some less-used aspect of the kernel. Yesterday I tried using a well tested kernel with a recent linaro rootfs and saw a similar panic as the display was coming up. No solutions at this point -Ash On Fri, May 18, 2012 at 3:17 AM, Sudhangathan B S wrote: > This is link from which I downloaded the image for nano..

Re: can I read Overo's madc registers...??
Hi, It looks like the Linaro kernel config. doesn't include these two config. options: CONFIG_TWL4030_MADC CONFIG_SENSORS_TWL4030_MADC I'd suggest adding these two options manually if you feel like compiling your own kernel or perhaps using Steve Sakoman's script if you just want a working system (http://sakoman.com/category/8-gnome-daily-builds-r13.html). For the Linaro folk: what is the policy on changing config. options? What is the best way for the community to request changes?

Re: Overo stability problem/Overo hwpack support
Packaging Repository First, grab the pre-existing packaging repository. $ bzr branch lp:u-boot-linaro Next, add a changelog entry. This adds your name to the debian/changlog file so the generated packages are signed with your GPG key. $ dch -i (increment...new section) $ dch -a (append...add to existing change) $ dch -r (change to released) The release version number in the changlog should match the version number found in the name of the source tarball. Now, from within the u-boot-linaro packaging repository, build the source package. $ bzr builddeb -S This generates sources packages in the parent directory. Make a new directory and build the binary packages $ cd .. $ dpkg-source -x *.dsc $ cd $ debuild -eCROSS_COMPILE=arm-linux-gnueabi- -b -aarmel -k$GPGKEY == Kernel == The kernel is regrettably tricky as it requires two debian packages: A) a package containing the kernel. Simple enough right? B) a meta-package that depends on the the kernel package. This way, the kernel package can't be apt-get autoremoved. == Kernel Package == Note, if you just want to test a kernel image on hardware, stop here and look at this page instead: https://wiki.linaro.org/Resources/HowTo/KernelDeploy To build a kernel debian: $ dch --changelog debian.linaro/changelog --package linux-omap3 -v 2.6.38-1002.4 $ fdr clean $ fdr updateconfigs $ debuild -eCROSS_COMPILE=arm-linux-gnueabi- -k$GPGKEY -b -aarmel On the target, # dpkg -i To build a kernel normally (https://wiki.linaro.org/Resources/HowTo/KernelDeploy): 1. Get a config from an existing build e.g.: $ scp root@overo.local:/media/rootfs/boot/config-2.6.38-1002-linaro-omap .config -- OR -- $ cat debian.linaro/config/config.common.ubuntu debian.linaro/config/armel/config.common.armel debian.linaro/config/armel/config.linaro-omap > .config 2. Build $ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- uImage modules -j8 3. Install $ cp arch/arm/boot/uImage /media/boot/ $ make ARCH=arm INSTALL_MOD_PATH=/media/rootfs/ modules_install $ make ARCH=arm INSTALL_FW_PATH=/media/rootfs/ firmware_install 4. Run (at the u-boot prompt) # setenv loadbootscript '' # setenv console 'ttyO2,115200n8' # saveenv # run bootcmd 5. Generate an initramfs (from running target) # update-initramfs -c -k `uname -r` # mount /dev/mmcblk0p1 /mnt # mkimage -A arm -T ramdisk -C none -n "MY RAMDISK" -d /boot/initrd.img-`uname -r` /mnt/uInitrd (see https://wiki.linaro.org/Resources/HowTo/KernelDeviceTree for dtb) Like u-boot, you need the kernel source and some debian packaging. Fortunately, Linaro regularly packages these together: $ git clone git://git.linaro.org/ubuntu/linux-linaro-precise.git The debian.linaro directory contains all the debian magic that specifies the modules, abi, and the configuration file snippets that are concatenated to make the kernel configuration. Read this page twice: https://wiki.edubuntu.org/KernelTeam/KernelMaintenance The official procedure is https://wiki.linaro.org/Resources/HowTo/PackageYourOwnKernel but much of the work has been done already. Just setup with $ fdr clean $ fdr updateconfigs And then build: $ debuild -eCROSS_COMPILE=arm-linux-gnueabi- -b -aarmel -k$GPGKEY == Meta Kernel Package == This one is a little easier than the kernel. Simply clone and build... $ git clone git://git.linaro.org/people/jcrigby/ubuntu/linux-meta-linaro-natty.git $ make binary As you need to change the ABI etc., you'll want to modify the changelog. To build a meta-package, use $ dch --changelog meta-source/debian/changelog --package linux-meta-linaro -v 2.6.38.1002.4 $ make binary At this point, you have a custom u-boot, kernel and kernel meta package which can be specified as local-debs for linaro-hwpack-create. == RootFS == Traditionally, Debian root file systems have been built natively. The Live-Build tool can be used to create a custom root file system in a cross-build environment such as multistrap. The instructions here https://wiki.linaro.org/Platform/DevPlatform/CrossCompile/LiveBuild summarize the process well. Package seeds are here: https://code.launchpad.net/linaro To customize the branding, modify these packages: * linaro-plymouth-theme-logo * linaro-overlay (firefox default page etc.) https://wiki.linaro.org/TomGall/HowToBrand == Entertaining Extras == To get the toolchain, $ sudo apt-get install gcc-arm-linux-gnueabi To build QEMU (http://wiki.gumstix.org/index.php?title=Overo_emulation_in_qemu): $ ./configure --target-list=arm-softmmu $ make -j8 Tell bzr who you are $ bzr whoami "Ash Charles " Add some handy stuff to .bash_aliases: alias fdr='fakeroot ./debian/rules' export DEBEMAIL="ashchar...@gmail.com" export DEBFULLNAME="Ash Charles" export GPGKEY="869D18EC" === Useful Links === * https://wiki.linaro.org/CategoryHowTo * https://wiki.linaro.org/Platform/DevPlat
Re: Gumstix Overo Support
Hi Steffen, The Overo COM is a community-supported board for Linaro meaning that Linaro doesn't dedicate resources to fixing bugs or enabling new features for this board. That said, Linaro engineers have been more than willing to accept patches from the community and ready to help me (and other Overo users) out on the IRC channels in making sure Overo (and OMAP3 in general) is well-supported by the Linaro image. For example, the change in April was a patch to make sure that Overo had the latest and greatest u-boot support. Currently, the Linaro kernel is missing a few patches and has a few different choices for config. options that aren't ideal for Overo. That said, you can test out the build available here: http://wiki.gumstix.org/index.php?title=Installing_Linaro_Image I work at Gumstix and I'm personally interested in supporting Overo within the Linaro community not least because I stand to learn a lot along the way!

Re: Making it easier for Linaro users to help themselves
Hello, > Part of the problem seems to be that we may not do a good job of > passing on the knowledge and understanding necessary to allow > users to help themselves. I don't know if you want user feedback on this thread but here goes... I started playing with Linaro about a year ago coming from an OpenEmbedded and direct cross-compilation background. The most challenging part of the learning curve has been moving from the 'Hey, I downloaded something and look it works' (Linaro does a brilliant job of making this really easy) to 'hmm...I want to change something but there is all this packaging in the way'. For me, this typically means I want to test a change to the kernel or u-boot for Overo. Moving from the standard compile-and-stick-on-a-microSD-card to the method of making debian packages (and understanding the implications of not doing so) was a learning curve. Not all users want to change the kernel but helping users learn to customize the Linaro deliverables (specify specific packages in an image, rebuild packages with different options...) seems important. Other notes: I have heard of other users getting confused by hardware packs---I actually thought this was well-explained but again struggled trying to build my own. Two pages that I keep bookmarked are * https://wiki.linaro.org/Resources/HowTo * https://wiki.linaro.org/CategoryHowTo (because sometimes I need that magic tip on some page that isn't listed above) as I usually know roughly what I wish to do but need an example of how to do it 'a la linaro'.

I just did a little digging online and there was some mention of ARM errata causing issues ( https://bugs.launchpad.net/ubuntu/+source/fakeroot/+bug/495536) Based on, https://github.com/gumstix/Gumstix-Overo-Kernel/blob/master/arch/arm/configs/overo_linaro_defconfig several of the errata are not set.
