[11:38:54] *** wbednarski has joined #chromium-os
[11:40:35] <darinski> saggu: the rootfs partition is created by build_image. it emerges binary packages built by build_packages
[11:55:50] <saggu> darinski : i want to build only rootfs for arm platform.. i am able to build kernel and u-boot images separetaly (thier source code is in src/third_party/kernel  & /u-boot)
[11:57:46] <saggu> moreover i followed the usual method like i gave build_package command then build_image which gave me single binary image chromium_image.bin, to which i futher unpacked and obtained 12 parts..
[11:58:58] <darinski> saggu: part 3 is rootfs
[11:59:38] <saggu> then as mentioned in specs i used part_3 as rootfs and used it along with the kernel and u-boot images (obtained independently earlier) to run with qemu-system-ar
[11:59:47] <saggu> qemu-system-arm*
[12:00:45] <saggu>  i am stuck with the screen that kernel is booted up but not able to load rootfs
[12:00:57] <saggu> can u suggest me what should i do ?
[12:02:12] <darinski> i don't know enough about this part... look for log messages on why you can't load rootfs... maybe you need to disable rootfs verification (look for the build_image option). but this is really shooting in the dark..
[12:03:14] <saggu> hmm... the logs were telling that there could be sync problem between rootfs and kernel...
[12:04:06] <saggu> i had disabled the rootfs verification
[12:06:10] <darinski> saggu: not sure what to suggest. make sure you follow all steps in build_image after you've built your own image. for example, it runs cros_make_image_bootable at some point.
[12:06:11] <saggu> i am not i am doing it right it or not ... but i am following the technique used to boot up any standard linux os ...which need u-boot.bin kernel image and a rootfs image with qemu emulator
[12:07:37] <saggu> cros_make_image_bootable works fine only when its build for x86 platform.
[12:08:08] <saggu> but here i am builing for arm platform and it gives error while building bootable image
[12:09:50] <darinski> saggu: chances are nobody's made this flow work yet. you'd need to debug :-) or ask questions when people who're more familiar with the boot setup are awake and online -- i.e., US daytime.
[12:10:46] <ojn> saggu, what are your bootargs to the kernel? and how are you attaching the rootfs, on what device?
[12:12:55] <saggu> ojn : i am giving qemu command like " qemu-system-arm -M versatilepb -m 512 -kernel uImage.bin -rootfs part_3 and some more parameters"
[12:13:19] <ojn> what is your kernel commandline?
[12:13:53] <saggu> its there in the qemu command i.e -kernel uImage.bin
[12:14:18] <ojn> no. what are your bootargs to the kernel? not what kernel you are asking qemu to load
[12:14:25] <saggu> kernel is boot up prorly but when roofs not .. its says that kernel is not in sync with rootfs
[12:14:41] <ojn> so what are the bootargs printed in the kernel output during boot then?
[12:15:21] <ojn> search for "Command line" in the kernel output
[12:15:23] <saggu> the kernel image is for versatlepb board on arm achitecture..
[12:15:36] <saggu> let me checke what more prints are there
[12:25:08] <saggu> ojn : after kernel is boot up properly ,, the prints are Root-NFS : no server address
[12:25:29] <saggu> then VFS : Unable to mount rot fs via NFS
[12:25:32] <ojn> saggu, you are making it hard to help you. please answer my question.

[13:20:27] <saggu> i think i need to first get the prob resolve with kernel ..and get the u-boot to load kernel properly then should got for rootfs..

[23:21:17] <dianders> ...sigh, stumpy canary fails again.  With a different error this time, it looks like.
[23:24:25] <daveparker> Continuing my adventures in building chrome browser...now I'm getting: ERROR: Commit 6ac8f50a79e41f82831073091a1d012d40397d04 not found in /home/dparker/trunk/chromium/src/third_party/adobe/flash/binaries/chromeos.
[23:24:39] <daveparker> does anyone know where this sha1 is coming from? A deps file somewhere?

[23:25:44] <kliegs> daveparker: probably the DEPS.git repo I think.  but I'm mostly guessing
[23:27:18] <dianders> dparker, kliegs: yup

[23:33:42] <rcui> daveparker: that's another double-checkout manifest issue from last week - please remove the src/third_party/adobe/flash/binaries/chromeos entry from your manifest.xml for now, and instead manually checkout the correct project to the location specified in the chromium/src-internal/.DEPS.git file

[23:37:50] <dianders> ...still waiting on artifacts for stumpy canary failure (almost done), but considering reopening http://crosbug.com/18823 for it.  Want to look at the autotest debug logs first...
[23:41:07] <daveparker> P.S. Hidden files: grumble grumble.
