device tree validation

by Tom Gall

Are there any tools for validating device tree files? I'm getting a device tree header not valid error in rtsm err:-9 but obviously that doesn't give any hints about what line it might be. Thanks! -- Regards, Tom "Where's the kaboom!? There was supposed to be an earth-shattering kaboom!"

Now on the real bit of fun that I want to get to the bottom of. This is from startx on the model. I have -C cache_state_modelled=0 set. Would that have an affect here?

aarch64 fails to boot in model

by Tom Gall

Hi, So I'm trying to boot an aarch64 kernel with the FVP simulator. Specifically I'm using the latest open embedded hwpack: hwpack_linaro-vexpress64-rtsm_20131216-560_arm64_supported.tar.gz and then an experimental OE image that I put together myself. The kernel however doesn't even start. Last thing I get after the count down is ERROR : Did not find Linux kernel and it dumps me into the boot manager menu. I used linaro-media-create to make the image. linaro-media-create --dev fastmodel --output-directory . --image_size=2000M --hwpack ./hwpack_linaro-vexpress64-rtsm_20131216-560_arm64_supported.tar.gz --binary ./linaro-image-xfce-genericarmv8-20140115214956.rootfs.tar.gz Thoughts? -- Regards, Tom "Where's the kaboom!?

First Ubuntu Trusty test rebuild (main component, all architectures)

by Matthias Klose

The first test rebuild of Trusty Tahr was started last week for all architectures (main component only). It is still running for arm64, all other architectures did finish the test rebuild. Results can be seen at http://people.ubuntuwire.org/~wgrant/rebuild-ftbfs-test/test-rebuild-201401… The archive for the test rebuild is https://launchpad.net/ubuntu/+archive/test-rebuild-20140108/ The test rebuild was done with a change which is not yet in the archive, changing the default Python3 to use the not yet released Python 3.4. These packages can be found in a ppa [1]. Please ask on IRC (#ubuntu-devel) if you are in doubt that a build failure is caused by the changed Python3 default. Additional build failures for packages in trusty-proposed (not yet in trusty) can be found at http://qa.ubuntuwire.com/ftbfs/ Please help fixing the build failures for the final release. Planning the next test rebuild for amd64, i386 and armhf for all components for the next week. Matthias [1] https://launchpad.net/~ubuntu-toolchain-r/+archive/python3

Galaxy Nexus: 13.10 Linaro android prebuilt image freezes at boot splash

by Chao Xu

Hello, I used the merge-gnexus-blobs script to flash the prebuilt image. The script worked smoothly except the make_ext4fs gave me a segmentation fault. So instead I just downloaded a prebuilt binary of make_ext4fs from here: https://code.google.com/p/archlive/downloads/detail?name=make_ext4fs.7z Then the script ran to the end and the phone rebooted. But it freezed at the boot splash of "google". My host is running ubuntu 12.04 64bit. I couldn't think of anyway to debug this problem and google doesn't help much. So any suggestion is appreciated. Thanks! -- Regards, Chao Xu

I am seeing a behaviour where the load variations are very frequency between 1ghz and 300mhz in a very short interval of time giving the ping-pong effect. \ Is there a way of avoiding this Also, is it possible to find out which task is causing this behaviour. All this happens in a couple of sampling periods of ondemand. -- Regards, Sriram

Anyone using virtio on armv7?

by Ryan Harkin

Hello, I'm trying to fire up an ARM fastmodel using a virtio block device rather than the emulated MMC block device. UEFI is reading the kernel & DTB off the virtio device, so I know the device is present. I added this to my kernel config: diff --git a/linaro/configs/vexpress.conf b/linaro/configs/vexpress.conf index 83acca8..2582450 100644 --- a/linaro/configs/vexpress.conf +++ b/linaro/configs/vexpress.conf @@ -58,3 +58,12 @@ CONFIG_LEDS_GPIO=y CONFIG_LEDS_TRIGGERS=y CONFIG_LEDS_TRIGGER_HEARTBEAT=y CONFIG_LEDS_TRIGGER_CPU=y +CONFIG_NET_9P=y +CONFIG_NET_9P_VIRTIO=y +CONFIG_VIRTIO_BLK=y +CONFIG_VIRTIO_NET=y +CONFIG_VIRTIO_CONSOLE=y +CONFIG_VIRTIO=y +CONFIG_VIRTIO_BALLOON=y +CONFIG_VIRTIO_MMIO=y +CONFIG_VIRTIO_MMIO_CMDLINE_DEVICES=y So far, I don't see any vda devices being enumerated (or any other virtio messages) and it rootwaits for /dev/vda2. I'm launching the model like this: FVP_VE_Cortex-A15x1 -C motherboard.flashloader0.fname=$UEFI -C motherboard.flashloader1.fname=uefi-vars.fd -C motherboard.flashloader1.fnameWrite=uefi-vars.fd -C motherboard.pl011_uart0.unbuffered_output=true -C motherboard.smsc_91c111.enabled=1 -C motherboard.hostbridge.userNetworking=1 -C motherboard.virtioblockdevice.image_path=linaro.img My kernel boot log is here: https://pastebin.linaro.org/view/97165b9e Model version: Fast Models [8.3.44 (Nov 20 2013)] Anyone had better luck using virtio on armv7 models and have any insights?
