| AdamOutler | hello! | 05:41 |
|---|---|---|
| AdamOutler | I was wondering if there was a guide somewhere which can lead me through obtaining Ubuntu/linux sources and compiling it into a boot.img? | 05:42 |
| AdamOutler | and a bootable drive. | 05:42 |
| twb | For what hardware? | 05:42 |
| AdamOutler | I am using a blaze-tabet based piece of equipment. | 05:42 |
| AdamOutler | Texas Instruments OMAP 4430, blaze tablet. | 05:43 |
| twb | There are prebuilt omap4 images | 05:43 |
| AdamOutler | It's a production version though and I have to recompile sources. | 05:43 |
| twb | Why? | 05:43 |
| AdamOutler | because the drivers are different. | 05:43 |
| twb | Uh, so just compile the drivers | 05:44 |
| AdamOutler | well, there's a caviet... it's a device based on blaze, it's actually a Nook Tablet... I located a security hole and it will only work for boot.img files. I need to use my own kernel on it. | 05:45 |
| AdamOutler | so, I'd like to find a guide on compiling a kernel from scratch and making a boot.img. | 05:45 |
| twb | I don't know what you mean by boot.img | 05:46 |
| AdamOutler | boot.img is Android standard.. basically it has to authenticate with the bootloader before it can be loaded. | 05:46 |
| twb | OK, a blobtools boot.img | 05:46 |
| twb | Er, I mean abootimg | 05:46 |
| AdamOutler | kinda. | 05:46 |
| AdamOutler | mkbootimg | 05:47 |
| twb | The tool I have seen that builds those is called "abootimg", apt-get install it | 05:47 |
| AdamOutler | I need some sort of guide though. | 05:47 |
| AdamOutler | ah ha! abootimg is a good tool | 05:48 |
| twb | To build the kernel, get an environment that can compile for your target architecture, then do "make zImage" or "make deb-pkg" to taste | 05:48 |
| twb | It would be a good idea to start with the stock ubuntu kernel and its omap4 .config | 05:48 |
| AdamOutler | twb, and abootimg handles zImage files? | 05:48 |
| twb | AdamOutler: I don't remember offhand | 05:48 |
| AdamOutler | ok, twb, what is a uImage? | 05:48 |
| twb | Different flavour of zImage, it's for u-boot | 05:49 |
| twb | If you are using the android bootloader (which takes abootimg boot.img files), then you don't want uImage. | 05:49 |
| AdamOutler | I have uImage and uInitrd.. they need to get into a boot img... I found a program that converts uImage to zImage, and now I need to convert uInitrd to initrd I guess. | 05:50 |
| twb | You probably want to prepare an Ubuntu rootfs, generate a kernel .deb, install the latter into the former, then run abootimg on the resulting kernel and ramdisk from /boot | 05:50 |
| twb | AdamOutler: if you already have a uImage why are you asking about kernel compilation? | 05:50 |
| AdamOutler | twb. you're opening my eyes. | 05:50 |
| AdamOutler | :) | 05:51 |
| AdamOutler | twb.. I've been compiling non-stop for a few days, I have several test images to work with in various formats. | 05:51 |
| twb | What hardware are you compiling on? | 05:51 |
| AdamOutler | stupid boot.img is tearing me up. | 05:51 |
| AdamOutler | twb, I'm cross-compiling from a i5 quad core for ARM arch | 05:52 |
| twb | That should compile in deciminutes, not days | 05:52 |
| AdamOutler | twb, it's operator error... this is why I asked for a guide when I came in ;) | 05:52 |
| twb | Try turning off the debugging symbols | 05:52 |
| twb | AdamOutler: it would be a good idea for you to get comfortable building normal x86 kernels first | 05:53 |
| AdamOutler | twb I am comfortable building 86_64 | 05:53 |
| twb | AdamOutler: that way you will have a solid foundation when you try to get a handle on the arm randomness | 05:53 |
| AdamOutler | twb, I've been operating several linux boxes in my home for years. I've compiled several for my media center alone. | 05:54 |
| AdamOutler | I'd just like some knoledge about all these formats and everything.. On my Samsung, I could just flash a zImage to my device and I was done.. This boot.img format is crazy. | 05:55 |
| twb | IIUC samsungs use u-boot and are generally on the "less stupid" side of ARM'd spectrum of idiocy | 05:55 |
| AdamOutler | zImage has Ramdisk+kernel. For some reason Boot.img has zImage + ramdisk, + android headers? | 05:55 |
| twb | zImage does not normally include the ramdisk | 05:56 |
| twb | The kernel has support for tacking a ramdisk onto itself -- this should work in both cases | 05:56 |
| twb | Normally the ramdisk is a separate file. | 05:56 |
| AdamOutler | ok, and what is the point of a ramdisk when the files are already on the root of the storage medium? | 05:57 |
| twb | To generate a boot.img using abootimg, you need a kernel, a ramdisk (optional), and a config file that basically consists of the options passed at the boot: prompt | 05:57 |
| twb | AdamOutler: the primary reason to use a ramdisk, is so you can build a small portable kernel and then include device-specific drivers to *get to* the root fliesystem, in the ramdisk | 05:57 |
| twb | That is how e.g. Ubuntu x86 servers all share the same kernel despite having different SATA controllers and video cards | 05:57 |
| twb | You can also put various other clever code in the ramdisk, e.g. this is how live CDs are made to look writable | 05:58 |
| twb | There is probably a paper somewhere that describes the linux boot process in detail; I don't have one handy to recommend. | 05:59 |
| AdamOutler | I think this is what I need. | 05:59 |
| AdamOutler | the paper describing the Uboot/Linux boot process. I really need to sort out these formats. | 05:59 |
| AdamOutler | you're making me much smarter though twb. I appreciate it. | 06:00 |
| AdamOutler | may I ask what you do for a living? | 06:00 |
| twb | http://prisonpc.com/ | 06:01 |
| AdamOutler | thanks for your help. | 06:06 |
| AdamOutler | twb.. one more thing before I go.. On the pre-compiled version, the touchscreen is 90 degrees off, and the wifi is totally inop. Any suggestions before I go trying to mix and match and recompile a few more things? | 06:09 |
| AdamOutler | https://plus.google.com/u/0/104711040110222472212/posts | 06:09 |
| twb | xrandr may help the latter if you are using X | 06:09 |
| twb | Er, the former | 06:09 |
| twb | wifi will probably be a missing firmware blob or soemthing | 06:09 |
| twb | http://openbsd.org/lyrics.html#39 | 06:10 |
| twb | You'll need to find someone who knows about your hw | 06:13 |
| AdamOutler | ok.. I found out about the xrandr thing, but I'm having a problem getting getty to work. I have a UART console hooked up, but I can't get shell access no matter what I do. | 06:14 |
| AdamOutler | I think it may have to do with the kernel being compiled with ttyS2 instead of ttyO2 for the default? | 06:14 |
| AdamOutler | I'm monitoring on ttyO2 | 06:14 |
| twb | Never heard of ttyO2 | 06:14 |
| twb | I've only seen ttyACM0 or so, plus the usual tty1 and ttyS0 | 06:15 |
| AdamOutler | /dev/ttyO2 is Texas Instrument's serial administration console. | 06:15 |
| twb | ok | 06:15 |
| AdamOutler | On samsung devices it's /dev/ttySAC2 | 06:15 |
| twb | Well, you can just pass console=/dev/ttyO2 | 06:15 |
| twb | On the boot: prompt | 06:16 |
| AdamOutler | I can make this device and get output from it.. I just can't seem to send any input. this would solve about 99% of my problems. | 06:16 |
| twb | Also in /etc/init/ there is a ttyN.conf you need to make one for O2 | 06:16 |
| AdamOutler | I can't pass arguments. | 06:16 |
| twb | What output are you seeing? The linux kernel boot messages? A tty login prompt? Both? | 06:16 |
| AdamOutler | I'm only getting kernel boot messages. I have tried several things including creating a S80StartConsole in /etc/RCS.d, creating my device on the /dev/ folder with the proper chmod params, and creating a /etc/init/ttyO2.conf | 06:18 |
| twb | you probably got ttyO2.conf wrong, pastebin it | 06:19 |
| AdamOutler | http://pastebin.ubuntu.com/805911/ | 06:20 |
| twb | Assuming the baud rate is right, looks OK to me. | 06:20 |
| AdamOutler | I've tried with those params and a -L instead of 8n | 06:20 |
| twb | Oh, and "rc RUNLEVEL=..." looks wrong. | 06:20 |
| twb | Never mind, it looks like that's the style used for other getty .conf | 06:21 |
| twb | I'm used to "start on runlevel [2345]" and "stop on runlevel [^2345]" | 06:21 |
| twb | I'm used to "start on runlevel [2345]" and "stop on runlevel [!2345]" (braino) | 06:21 |
| AdamOutler | I'll try that. | 06:22 |
| AdamOutler | next time. | 06:22 |
| AdamOutler | my s80StartConsole contains "start ttyO2" and a bunch of other things. I have determined it is run as root so I have a way to make things happen, I just don't know what needs to happen. | 06:23 |

| S0NiC | hi | 12:30 |
| S0NiC | hmm is it possoible to play on a pandaboard any mp4 video? is this supported? | 12:31 |
| taruti | S0NiC: just use mplayer? | 12:32 |
| ogra_ | only supported in totem | 12:33 |
| LetoThe2nd | ogra_: depends on the desired playback speed ;) | 12:33 |
| ogra_ | mplayer would only try to do it in sw ... all gstreamer based players can use the hw acceleration of the panda (if you have the codecs installed= | 12:34 |
| S0NiC | ogra_: wich codecs would that be? | 12:34 |
| ogra_ | LetoThe2nd, indeed, i should have said that mplayer is great for turning mp4 movies into slideshows instead :) | 12:34 |
| ogra_ | S0NiC, just install the ubuntu-omap4-extras or the ubuntu-omap4-multimedia packages after you enabled the PPA | 12:35 |
| LetoThe2nd | S0NiC: maybe have a good look at http://rsalveti.wordpress.com/2012/01/06/hw-video-decode-and-xbmc-ubuntu-linaro/ | 12:35 |
| LetoThe2nd | ogra_: cool use case that is ;) | 12:35 |
| ogra_ | (they get installed by default after you clicked the TI desktop item on the images) | 12:35 |
| ogra_ | LetoThe2nd, well, ubuntu-tv extensively makes use of xbmc ;) | 12:36 |
| S0NiC | thx | 12:36 |
| LetoThe2nd | ogra_: havent gotten round to try it yet :/ | 12:36 |
| S0NiC | hmm wich kind of video works out of the box? | 12:36 |
| S0NiC | *codec | 12:36 |
| S0NiC | does anybody know? | 12:39 |
| LetoThe2nd | S0NiC: any video works out of the box, but none with hw accel. thats why the ppa is there. | 12:40 |
| S0NiC | LetoThe2nd: ok that means i have to enable hw acceleration. what means ppa in this case? | 12:40 |
| LetoThe2nd | S0NiC: basically http://omappedia.org/wiki/PandaBoard_Ubuntu_PPA, no idea how uptodate the instructions are. | 12:41 |
| ndec | the codecs which are h/w accelerated on OMAP4 are MPEG2, MPEG4, H263, H264, VC1 (WMV) | 12:43 |
| S0NiC | LetoThe2nd: but i think your link http://rsalveti.wordpress.com/2012/01/06/hw-video-decode-and-xbmc-ubuntu-linaro/ is good. but i have to create a new image... | 12:43 |
| ndec | just start with the default 11.10, upgrade it, reboot, and install the TI adds on. | 12:43 |
| ndec | that should be a good start. | 12:43 |
| S0NiC | ndec: mom | 12:44 |
| S0NiC | ndec: ok, iam using 10.10 at the moment... | 12:45 |
| ndec | ouch... | 12:45 |
| LetoThe2nd | urgh | 12:45 |
| ndec | any good reason to stick to 10.10? | 12:45 |
| LetoThe2nd | "ancient technologies and wisdom of the olde"? | 12:45 |
| S0NiC | ndec: no | 12:46 |
| S0NiC | ok, dann i update, | 12:46 |
| ndec | 11.10 has better OMAP support, and more codecs. and is maintained in case you face an issue | 12:46 |
| S0NiC | what is ment by the "ti adds" | 12:46 |
| S0NiC | ? | 12:46 |
| ndec | hum, my advice is to restart from scratch, don't dist-upgrade a 10.10 system into 11.10. | 12:46 |
| LetoThe2nd | S0NiC: the ti addons for hw accel | 12:46 |
| ndec | once you install 11.10 image, there will be an icon to install the TI 'addons' on the desktop. just click | 12:47 |
| S0NiC | i get them with apt-get....? | 12:47 |
| ndec | yes you can too. | 12:47 |
| S0NiC | ndec: ah cool | 12:47 |
| LetoThe2nd | S0NiC: have you actuelly read the links? | 12:47 |
| S0NiC | thanks guys | 12:47 |
| S0NiC | LetoThe2nd: only your link | 12:47 |
| S0NiC | now i have a lot to do ;D | 12:47 |
| ndec | but make sure that you run apt-get update & apt-get dist-upgrade before you install the TI stuff. some people have reported that there are issues otherwise | 12:47 |
| LetoThe2nd | S0NiC: i doubt it, because then you would know how to install them ;) | 12:48 |
| LetoThe2nd | one could also aim directly for the tv release that ricardo pointed to... | 12:50 |
| S0NiC | ok | 12:51 |
| S0NiC | thx | 12:51 |
| S0NiC | ok i have to leave cya later... | 12:52 |
| S0NiC | thx bye | 12:52 |
| LetoThe2nd | side note: his original question was in #ubuntu-de why 'apt-cache search vlc' did not yield any results :) | 12:54 |
| ogra_ | oh, it should | 12:54 |
| LetoThe2nd | ogra_: on ancient 10.10, and a user that doesn't know how to handle a ppa? ;) | 12:55 |
| * ogra_ gets more than a terminal page | 12:55 | |
| ogra_ | doesnt matter, vlc is in universe, he should even have seen it on 10.10 | 12:55 |
| ndec | i guess he didn't enable universe | 12:56 |
| ogra_ | yeah, smells like | 12:56 |
| ogra_ | and 10.10 had a bug with the default sources.list iirc | 12:56 |
| ogra_ | which we fixed in an update | 12:56 |
| LetoThe2nd | smells like nirvana... erm, teen spirit ;) | 12:56 |
| ogra_ | hehe | 12:56 |
| * ogra_ had totally forgotten ubuntu-de ... i used to be resident there ... but i find IRC in german weird and have probs to not write half my sentences in english | 12:57 | |
| LetoThe2nd | ogra_: the traffic there receded quite a bit over the last 3 or 4 years, after we enforced more and more to stay on topic, and in the meantime rejected to support weird offshoots/derivates/whatevers ;) | 12:58 |
| ogra_ | yeah, i remember that kind of discuaaions | 12:59 |
| LetoThe2nd | ogra_: you wouldn't believe how many people come there bit***ing around when you reject to support mint or debian. | 12:59 |
| ogra_ | oh, i would :) i see the same bitching in bugs ... | 12:59 |
| LetoThe2nd | ogra_: hehe | 13:00 |
| ogra_ | rarely debian, but often mint users freak out that we dont support their ubiquity bugs for the hacked up mint installer | 13:00 |
| LetoThe2nd | ogra_: it has emerged that when the slightest doubts arise we ask for lsb_release -a and uname -a. | 13:00 |
| ogra_ | and mint does serious bad things when customizing the distro | 13:00 |
| LetoThe2nd | ogra_: yeah, thats why we reject to support it. | 13:01 |
| ogra_ | like disabling security updates for things like X11, kernel, dbus etc | 13:01 |
| ogra_ | (or bootloaders) | 13:01 |
| ogra_ | s/security updates/all updates/ | 13:02 |
| LetoThe2nd | ogra_: hehe | 13:02 |
| LetoThe2nd | lets be glad they don't have an arm port yet. | 13:03 |

| AdamOutler | I've sucessfully created a boot.img that apparently works, however I am running into an error. "Unrecognized/unsupported machine ID".. | 20:20 |
| AdamOutler | Is there a way to change this in my kernel? | 20:20 |
| AdamOutler | I'm using precompiled binaries | 20:20 |

| vani | <AdamOutler> sorry I cannot help you on this as I'm new to ARM ports. But, I'm trying to piggy back on you. | 21:20 |
| vani | How did you create the boot.img... | 21:20 |
| vani | any notes or references...I'm having a board with ARMv7 | 21:20 |
| vani | trying to build a custom image for it... | 21:21 |
| LetoThe2nd | the machine ID refers to the ID that the first/second stage bootloader passes to the kernel. the kernel uses this ID to decide which board file to use. | 21:25 |
| LetoThe2nd | if the kernel doesn't know about the ID, it will not boot. so make sure kernel and bootloader (u-boot in most cases) match. | 21:25 |

| AdamOutler | oh | 22:17 |
| AdamOutler | hi | 22:17 |
| LetoThe2nd | concerning your question from some time ago. | 22:17 |
| AdamOutler | ok... so can I spoof this from U-Boot prompt somehow? | 22:17 |
| LetoThe2nd | hopefully not. | 22:17 |
| AdamOutler | LetoThe2nd, this is a Blaze Tablet based device. | 22:18 |
| AdamOutler | LetoThe2nd, I'm pretty sure I should be able to get something from the device by spoofing the id | 22:18 |
| LetoThe2nd | AdamOutler: its three parts altogether 1) get/register the machine ID at arm.linux.co.uk 2) make sure the bootloader passes this ID 3) make sure the kernel contains a board support file bound to this id. | 22:19 |
| AdamOutler | LetoThe2nd, the link you provided is bad. | 22:51 |

| mythos | register what? | 23:23 |
| mythos | is it possible to start a dovel-kernel with qemu? | 23:39 |
| GrueMaster | mythos: A which kernel? I think qemu wants a versatile kernel only. | 23:43 |
| mythos | yes, versatile runs perfectly. are you sure, that those dove-kernels don't run with qemu - i speak from those in maverick | 23:45 |
| mythos | 10.10 | 23:45 |
| mythos | and btw thanks for your response, GrueMaster =) | 23:45 |
| GrueMaster | The dove kernels are specifically for Marvell hardware. | 23:45 |
| GrueMaster | Same as the omap4 kernels are for TI omap4 processors. | 23:46 |
| mythos | hmm... ok, i see | 23:46 |
| mythos | good to know why qemu pretends to stay black =) | 23:46 |
| GrueMaster | And the Marvell kernel for Maverick was a bit of a mess anyways. It was the same as the Lucid kernel, just built with the Maverick tool chain. | 23:46 |
| mythos | i have a hp device here, which uses a maverick-debootstrab | 23:47 |
| mythos | it has marvell-hardware in it, so that fits | 23:48 |
| GrueMaster | Is it using a marvel soc? | 23:48 |
| GrueMaster | Cool. | 23:48 |

| GrueMaster | heh | 23:49 |
| NCommander | mythos: is that a thinclient by any chance? | 23:49 |
| mythos | NCommander, yes | 23:49 |
| mythos | a hp 5335z | 23:49 |
| NCommander | mythos: .... | 23:49 |
| mythos | i broke yesterday one | 23:49 |
| mythos | was not able to boot up anymore, after i zeroed /dev/sda | 23:50 |
| mythos | ^^" | 23:50 |
| GrueMaster | Yea, that would be a bad thing. | 23:51 |
| NCommander | mythos: I loathe to say this, but that thing is based around a Marvell Dove board. If they took my patches wholesale, it *might* boot with an Ubuntu maverick dove image off USB | 23:52 |
| mythos | no, it should boot up from a usb-device. but it simply did not | 23:52 |
| NCommander | mythos: open it up and find the serial header to get uboot access :-) | 23:52 |
| NCommander | mythos: what image did you try? | 23:52 |
| mythos | NCommander, i only messed around with the the image, which is downloadable from hp | 23:53 |
| * GrueMaster watches NCommander's version of the crying game, laughing hysterically. | 23:53 | |
| NCommander | mythos: http://cdimage.ubuntu.com/ubuntu-netbook/ports/releases/maverick/release/ | 23:53 |
| NCommander | try one of the dove images, and see if it boots | 23:54 |
| NCommander | instructions are ... somewhere | 23:54 |
| NCommander | ^- GrueMaster | 23:54 |
| mythos | NCommander, i'm going to try that =) | 23:55 |
| NCommander | mythos: if it works, please don't call me ;.; | 23:55 |
| * NCommander horrorifically flashs back to China | 23:55 | |
| mythos | don't? | 23:55 |
| NCommander | mythos: I was assigned to Antartica^W China for a month to do that image | 23:56 |
| mythos | ok, i won't | 23:56 |
| NCommander | I'm still scared from the experience | 23:56 |
| mythos | omg ^^" | 23:56 |
| NCommander | mythos: (actually, feel free to ping me, but what support I can give is limited) | 23:56 |
| mythos | my plan was to use the hp-image as skeleton | 23:57 |
| NCommander | mythos: alternatively, you might need to open it up, pop the HDD, and then do some creative repartitioning | 23:57 |
| mythos | hdd? there is no hdd inside them ^^" | 23:57 |
| NCommander | what compelled you to zero sda though? | 23:57 |
| NCommander | oh good, they fixed that 'bug' | 23:58 |

| NCommander | mythos: so depending on how they smacked uboot, the thing will either try and load an image off USB, or try and TFTP a blob off somewhere (you'll probably need to use ethereal to see where its trying to get a blob) | 23:59 |
| twb | NCommander: why did you need to go to .cn to make an ISO9660? | 23:59 |
| mythos | even though it is limited, that offer is very nice, NCommander =) | 23:59 |
| twb | ethereal is called wireshark these days btw | 23:59 |
