| brendand | anyone else got a problem with the oneiric final image on panda, where the horizontal alignment is way off? | 08:51 |
|---|---|---|
| brendand | well, it's more like it's horizontally squashed | 08:54 |
| infinity | Not here... | 08:59 |
| infinity | Though I haven't tested today's spin (about to), I don't see how it would be different from yesterday's. | 08:59 |
| ogra_ | infinity, hmm, frambuffer changes ? | 09:02 |
| ogra_ | *frame | 09:02 |
| ogra_ | (no idea how they could influence us, but werent there some in the initrd ?) | 09:03 |
| brendand | infinity - also once i get to lightdm it seems to kill the display | 09:06 |
| brendand | i just got the image this morning | 09:07 |
| infinity | I'm testing right now. | 09:08 |
| brendand | could just be my stupid monitor. i've had issues with it in the past | 09:11 |
| infinity | Well, sure, if you keep calling it stupid, I can see how that would cause issues in your relationship. | 09:12 |
| infinity | Try being less of a jerk to your monitor? :) | 09:12 |
| ndec | panda and monitors have always had difficult relationship as well.. | 09:16 |
| ogra_ | yeah, i suggested for the first release already that TI should just ship the pandas with a monitor | 09:16 |
| ogra_ | but they never listen to me :( | 09:16 |
| brendand | perhaps it's having its revenge | 09:19 |
| xranby | ogra_: i tried to install the omap extras package onmy panda today.. and .. poof no xorg | 09:20 |
| ogra_ | xranby, hmm | 09:21 |
| xranby | so the good news are that something are available in the ppa now | 09:21 |
| ogra_ | right, i guess we need to talk to rsalveti about that | 09:22 |
| ogra_ | the sgx packages come from linaro ... they have been tested there, probably some incompatibility with our kernel or so | 09:22 |
| xranby | i will download the latest oneiric panda image and retry | 09:23 |
| xranby | the image i used are some days old | 09:23 |
| ndec | ogra_: the sgx don't come from linaro... | 09:28 |
| ndec | but from TI | 09:28 |
| infinity | Indeed, it's all ndec's fault. | 09:28 |
| ndec | xranby: how exactly did you install the omap extra? | 09:29 |
| xranby | ndec: clicked on the nice shiny button | 09:29 |
| xranby | in the unity launcher | 09:29 |
| ndec | only that? | 09:29 |
| xranby | it opened the software center | 09:29 |
| xranby | and then i clicked on install | 09:29 |
| xranby | and it said it was done | 09:29 |
| ndec | that should not install anything since our meta package is empty. | 09:29 |
| infinity | ^ | 09:29 |
| xranby | it did install something on my board :P | 09:29 |
| ndec | so if that install nothing, that can't break anything ;-) | 09:30 |
| xranby | ok i will retest using the latest unadulterated oneiric image | 09:30 |
| ndec | i guess it installed ubuntu-omap4-extras, right? | 09:30 |
| infinity | It should just install an empty package. | 09:30 |
| infinity | ndec: Yeah. | 09:30 |
| ndec | xranby: check the version of the package, it should be 1.1~1 | 09:30 |
| infinity | He may have done this with an older image that still referenced the natty ppa. | 09:31 |
| infinity | Before I fixed that. :P | 09:31 |
| ndec | xranby: can you share the output of apt-cache policy | 09:31 |
| ndec | infinity: that's what i guesed ;-) | 09:31 |
| ndec | guessed | 09:31 |
| xranby | ndec: just a second | 09:33 |
| xranby | ndec: http://paste.ubuntu.com/706596/ | 09:38 |
| ogra_ | yep, all natty | 09:38 |
| xranby | ogra_: false alarm then, im fetching a new image | 09:41 |
| ogra_ | heh | 09:41 |
| brandini | morning | 12:51 |
| jeremiah_ | So I've got an Ubuntu root file system for my OMAP 3 beagleboard | 13:06 |
| jeremiah_ | But it won't boot on a new disk because in the boot.scr there is a UID that appears incorrect | 13:06 |
| jeremiah_ | Is there a way to fix that? | 13:06 |
| ndec | jeremiah_: update your boot.scr? | 13:08 |
| jeremiah_ | ndec: I tried to do that by hand but it doesn't seem to have any effect | 13:09 |
| jeremiah_ | Is there a way that is used by others? | 13:09 |
| ndec | jeremiah_: what do you mean by hand? | 13:09 |
| ndec | the boot.scr is generated with mkimage. | 13:09 |
| jeremiah_ | I edited the boot.scr in emacs | 13:09 |
| ndec | e.g. mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Ubuntu" -d ./boot.cmd ./boot.scr | 13:11 |
| ndec | from http://elinux.org/BeagleBoardUbuntu#Beagle_Bx.2FCx_.26_xM | 13:11 |
| jeremiah_ | Thanks ndec! I'll go read that URL | 13:11 |
| ndec | if you use a UUID you will need to use an initramfs, where the init will read the UUID and find the actual device to mount | 13:11 |
| ndec | so if you know the actual root device, you can use it in root= instead of UUID. | 13:12 |
| jeremiah_ | ndec: I thought the device I needed to specify was something like /dev/mmblk0 | 13:12 |
| jeremiah_ | but that doesn't seem to work. :( | 13:12 |
| ndec | /dev/mmcblk0p2 likely | 13:13 |
| brandini | I was reading through the docs last night and it almost seemed like I could format my usb thumb drive like I did the sd card and make it boot of teh usb drive | 13:13 |
| jeremiah_ | Ah, of cou! | 13:13 |
| jeremiah_ | rse | 13:13 |
| ndec | brandini: you cannot 'boot' from the usb drive, but you can boot from SD (mlo, uboot, uimage) and have the root fs on USB driver | 13:15 |
| brandini | ndec: the docs say first is usb, then mmc | 13:16 |
| ndec | brandini: ok... well you can boot from USB yes, but that's using a special protocol with the OMAP rom code. it's for OTG, not HOST. it's used for example for when you connect your phone to flash it... | 13:17 |
| brandini | ahhhh ok | 13:18 |
| brandini | so even if I put MLO and uboot on a thumb drive it won't boot properly from that? | 13:19 |
| ndec | brandini: no. it won't | 13:19 |
| ndec | you can do this http://omappedia.org/wiki/Ubuntu_on_OMAP_FAQ#I_want_to_install_Ubuntu_on_external_USB_hard_disk_instead_of_sluggish_SD_card | 13:20 |
| ndec | to put root fs on USB driver | 13:20 |
| ndec | drive | 13:20 |
| brandini | interesting | 13:22 |
| brandini | leave it to me to actually read the docs and get more confused :) | 13:22 |
| ndec | brandini: reading the docs is great , no confusion! | 13:23 |
| brandini | I didn't understand that there was a difference between the first boot device and the second | 13:25 |
| brandini | in how it tried to initiate the boot sequence | 13:25 |
| brandini | I thought no matter what the device was it would look for MLO, then uboot | 13:25 |
| ndec | brandini: the difference in 1st vs 2nd boot is not in mlo/uboot, that part never changes. | 13:39 |
| ndec | on 1st boot the initramfs will enlarge the partition and launch the installer. it will generate /etc/flash-kernel.conf | 13:39 |
| ndec | on further boots, the initramfs will directly mount the root fs | 13:39 |
| brandini | http://pandaboard.org/sites/default/files/board_reference/A1/Panda_Board_Spec_DOC-21010_REV0_6.pdf | 13:43 |
| brandini | so on page 21 where it talks about SYSBOOT | 13:43 |
| brandini | that's where I was reading that | 13:46 |
| brandini | the default is 000101 which says USB, MMC1 | 13:46 |
| ndec | brandini: and as i told you USB here does not mean what you were hoping. if you look at the OMAP4 TRM docs, there is a chapter on 'booting' | 13:47 |
| brandini | ok | 13:47 |
| brandini | I'm not saying I don't believe, just showing you how I got confused | 13:48 |
| ndec | sure. i know this doc. | 13:48 |
| brandini | I pulled down rev X of that last night... 5500 pages or something :) | 13:48 |
| ndec | and it's just the public version ;-) | 13:49 |
| brandini | lol | 13:50 |
| brandini | right | 13:50 |
| brandini | and there is a pretty extensive errata doc too | 13:50 |
| brandini | ndec: so I found the assembly source for booting the beagle on openbsd, it doesn't seem similar enough to actually boot the panda | 13:56 |
| ndec | i guess so | 13:56 |
| brandini | you guess so? | 13:56 |
| ndec | omap3 vs omap4? a8 vs a9 smp... | 13:57 |
| brandini | yeah | 13:57 |
| brandini | that's why I'm trying to read this TRM | 13:57 |
| brandini | wonder if looking at the ubuntu version is a good start | 13:58 |
| rOxx | hello, someone here who can help me with industrial i/o driver ? | 14:07 |
| brandini | ndec: I found some interesting stuff after reading 27.4.5.3 in the public doc :) | 14:50 |
| ndec | what's 27.4.5.3 exactly? | 14:50 |
| brandini | it explains what you were trying to tell me earlier about the booting of usb | 14:51 |
| ndec | ah! | 14:51 |
| brandini | s/trying to tell/telling/g | 14:51 |
| ndec | i am hoping i wasn't too far from the reality ;-) | 14:51 |
| brandini | you weren't at all | 14:51 |
| brandini | this is fun, I wonder how far I can go with this | 14:52 |
| === zyga is now known as zyga-afk | ||
| GrueMaster | brandini: On the omap4 usbboot, we are using that (or soon will be) in our panda build cluster. I already use it in my test setup. Really usefull for booting and clobbering SD image hands free. | 16:23 |
| === zyga-afk is now known as zyga | ||
| ndec | brandini: usbboot is indeed using the actual USB boot mechanism. (this refers to our discussion earlier) | 17:08 |
| brandini | :) | 17:25 |
| brandini | I want a panda build cluster! | 17:25 |

| diwic | <mkbosmans> is it always valid to cast a uint8 pointer to a uint32 pointer, even if the pointer is not 4-byte aligned? | 17:53 |
| diwic | anybody knows if the answer is "yes" on arm as well? | 17:54 |
| R_Nev | the kernel will trap and handle the unaligned accesses | 18:16 |
| R_Nev | by default, most likely, but it's going to be slow and i think it's possible to disable the fixup so that the app crashes instead | 18:18 |
| R_Nev | unaligned neon accesses may infinite loop instead | 18:23 |
