[00:00] <tassadar_> you probably don't want to build new initrd - it is easiest to just use existing one
[00:00] <tassadar_> kernel is stored in "boot.img" file, which can be built using "abootimg" tool, it is in Ubuntu's repositories, so you can just apt-get it
[00:01] <tassadar_> with it, you can extract existing boot.img, replace the zImage and build new boot.img
[00:02] <mmenefee> okay, yeah, I've seen a bit on that.
[00:03] <TheMuso`> tassadar_: Urm you do need a new init, particularly if the kernel version/uname -r output is different.
[00:03] <TheMuso`> initrd even
[00:03] <tassadar_> why would you?
[00:04] <TheMuso`> He built a custom kernel. It depends on how this was built, but the version string may have changed.
[00:04] <tassadar_> I don't think there are any kernel modules
[00:04] <mmenefee> I built a few things as modules...
[00:05] <mmenefee> I might be able to just push them into the rootfs...
[00:05] <tassadar_> even then, you probably don't need them in initrd
[00:05] <mmenefee> guess I've always just done kernels and initrds as pairs.  Old habits die hard...
[00:05] <tassadar_> are we talking about ubuntu touch or ubuntu desktop?
[00:09] <mmenefee> I _think_ desktop.  The raring desktop preinstalled for nexus7.
[00:09] <tassadar_> yeah, that's desktop
[00:09] <mmenefee> yeah, this boot.img: http://cdimage.ubuntu.com/releases/raring/release/ubuntu-13.04-preinstalled-desktop-armhf+nexus7.bootimg
[00:12] <mmenefee> the existing initrd.img is ~3MB, so it has _something_ in it.  I'll have to check what...
[00:12] <tassadar_> well, the init bash script and some basic tools to mount the system
[00:12] <tassadar_> *system partition
[00:13] <mmenefee> dumb question: are the build scripts used by the daily build servers in a git archive or some such?
[00:13] <tassadar_> it is built by update-initramfs and then flash-kernel package I think
[00:13] <mmenefee> might be helpful just to look at how the cdimage files are built...
[00:13] <tassadar_> or do you mean build scripts for whole image? I don't know about those
[00:14] <tassadar_> btw, abootimg -x created file "boot.cfg" or something like that. Remove parameter "bootsize" from it, and make sure you use this config file when rebuilding the boot.img
[00:15] <mmenefee> yeah, whole image.  I.e. what runs every day and pushes daily builds or releases out...
[00:15] <mmenefee> okay, I'll give it a rip
[00:17] <tassadar_> flash-kernel tool can probably be used to flash the kernel...hmm
[00:17] <tassadar_> without rebuilding the image
[00:17] <tassadar_> huh
[00:18] <tassadar_> you can probably just push the zImage to /boot, put modules where there belong and generate initramfs with "update-initramfs"
[00:18] <tassadar_> and ubuntu will take care of the rest
[00:20] <mmenefee> yeah, that works for checking it out... but if I want to replicate it to some other devices later
[00:20] <mmenefee> though, I guess I could just dd back off the device after I get it like I want it...
[00:20] <tassadar_> well, it would be better if you'd learn how to build the boot.img by yourself then, it's pretty easy with abootimg anyway
[01:46] <Brun0L3z> So I am totally confused and desperate, that is why I am here, I have an HP pavilion m6 with an inbuilt SD slot but when i plug in the SD card (4 GB) i do not get a mount,m nothing happens. I am thinking its a driver prob but i have no idea how to verify that.
[08:35] <Rjs> mmenefee: I'm not sure if I remember correctly (it's been half a year), but I think I built a custom kernel for nexus7 (desktop) simply by running debuild in the source directory (on the tablet, not cross-compiling) and installing the produced .deb with dpkg -i
[08:35] <Rjs> _if_ the other devices you want to replicate to already have ubuntu desktop installed, a .deb package is probably the cleanest way to replicate a new kernel (that way versions etc. are also visible in apt)
[08:41] <Rjs> (I also remember trying to find the scripts that generate the ubuntu preinstalled images, but I didn't find them, or any documentation on how exactly these images differ from plain ubuntu or debian armhf... though I didn't look very hard)
[22:17] <cjoseph> we have an AM3505 CPU in our system. Has anybody used ubuntu with this processor or a related one?
[22:18] <cjoseph> we curently use something called WindRiver linux, but are considering changing
[22:44] <hrw> cjoseph: am3505 is omap3 or sitara family from TI
[22:45] <hrw> cjoseph: perfectly fine to run ubuntu as long as you will take care of bootloader and kernel stuff
[22:45] <hrw> cjoseph: but no idea how X11 and video/opengles acceleration would look like
