| AmEv | Hi | 00:02 |
|---|---|---|
| AmEv | Anyone here able to troubleshoot Tegra 2 non-booting problems? | 00:07 |
| AmEv | Anyway, the tablet I'm trying to install Ubuntu onto is the Toshiba thrive. Biggest possible issue I see? The version of Tegra 2 it is. | 00:16 |
| AmEv | Is it a Harmony Tegra 2? Nope. Ventana? Nope. It's in its own ball park: the Antares. | 00:18 |
| RaYmAn | it's irrelevant. It's ventana based, but it doesn't really matter. THe drivers work on any tegra2 as long as it has the right kernel | 00:18 |
| AmEv | Hmm... | 00:19 |
| AmEv | Anyway, I'm hitting two things that are happening: Either it stays at the bootup logo, or the screen goes black, and the backlight goes off. | 00:20 |
| AmEv | I do get some garbled display on HDMI, either way. | 00:21 |
| AmEv | So, are there some essentials I need to have configured, besides VT and framebuffer console? | 00:21 |
| RaYmAn | what kernel are you using? | 00:22 |
| AmEv | I'm trying to build my own, as nobody has released one for the Thrive. However, what I'm starting to use is at this git: https://github.com/pio-masaki/at100-kernel | 00:25 |

| AmEv | *released a GNU kernel, that is. | 00:25 |
| infinity | I do wonder if our ac100 kernels might Just Work on it. | 00:28 |
| AmEv | Compile for Ventana instead of Harmony? | 00:28 |
| AmEv | Both are Toshiba. That's good news. | 00:29 |
| infinity | I've never seen a Thrive in person to play with it, but I'd always had a sneaking suspicion that (with the exception of a few peripherals) it's identical to the ac100. But, who knows. | 00:30 |
| AmEv | Heh. One of the Thrive devs would love to have an AC100. Can't afford it, though. | 00:31 |
| infinity | If I were the Toshiba engineers, the ac100 would have just been my devel version of the at100 (cause keyboards are handy for debugging). | 00:31 |
| AmEv | Downloading AC100 kernel source. | 00:31 |
| infinity | You could just grab the debs and try the binaries for a quick "hey, maybe this works" smoketest. | 00:32 |
| AmEv | I've prepared a rootfs on an external SD card already. | 00:32 |
| AmEv | It's actually a Plasma Active rootfs, but with my touch screen dying (cracked)... At least we have LXDE. | 00:33 |
| AmEv | Yeah... As nice as a VNC for Android solution is, it's extremely laggy, to the point of almost unusability. | 00:34 |
| infinity | I've been seriously considering dropping Tegra2 support from future Ubuntu versions. If people are still actively developing on them, I may need to bring this to a community vote/discussion. | 00:34 |
| AmEv | Heh. The reason I chose the Thrive about a year ago was because it seemed to be a perfect candidate for Ubuntu. | 00:36 |
| infinity | Yeah. And we've had a policy of no-neon-by-default specifically because of the Tegra2 (the only SoC we support that doesn't have NEON). | 00:36 |
| infinity | It's irksome to keep patching upstream sources for this assumption, but if the target is still widely developed on/with, we may have to stick with it for a bit. | 00:37 |
| AmEv | Seems that performance development is slowly shifting away from x86 and going to ARM... | 00:38 |
| infinity | About time. ARM could use more performance-oriented tweakers. | 00:39 |
| AmEv | I do like ARM because of its power-performance ratio. | 00:40 |
| infinity | Yup, and that ratio can only improve as more people start hand-tuning code the same way they've done for x86, rather than falling back to generic C implementations. | 00:41 |
| infinity | (But NEON is a big part of that story... hand-tuned NEON can be blazingly fast but, sadly, leaves Tegra2 out to dry) | 00:41 |
| AmEv | I'm no CPU design expert, but it seems that x86 is starting to hit a performance ceiling. | 00:42 |
| infinity | Well, not all that sad. Just annoying that ARM allowed NEON to be optional so NVIDIA could make that silly decision. | 00:42 |
| claes | is this the right place to ask about what rooting option to choose from the google nexus 7 toolkit, to then install multrom and dualboot android and ubuntu?. if so wich rooting option should i choose, its a bit confusing. | 00:42 |
| infinity | claes: https://wiki.ubuntu.com/Nexus7/Installation has clear unlocking instructions. | 00:43 |
| infinity | claes: We don't support installing in a dual-boot setup, though, you're on your own for figuring that one out. | 00:44 |
| claes | ok thanks | 00:44 |

| AmEv | Well, porting Ubuntu Phone to a spare phone I've got should be fun... | 00:48 |
| xnox | AmEv: can it run android stock kernel? that would be first step. | 00:58 |
| AmEv | It's actually a WebOS phone. | 00:59 |
| AmEv | Meets bare-minimum requirements, with OC... | 00:59 |
| AmEv | As for the Thrive, should I use the Google cross-compiler toolchain? | 01:00 |
| AmEv | Got a Ventana Android defconfig... | 01:02 |
| AmEv | And a Harmony GNU config.. | 01:02 |
| AmEv | Really? No Ventana GNU config on Google? | 01:04 |
| AmEv | Or is it under another name? | 01:05 |
| AmEv | Hmmm.. The one guy ported CM10 to the Thrive. Said that the Thrive was almost identical to the Iconia a500.... | 01:14 |
| AmEv | And it's a Harmony board.... | 01:15 |
| lilstevie | AmEv: the Iconia a500 is a picaso board not a harmony board | 01:17 |
| lilstevie | AmEv: Harmony is the name of one of the dev boards made by nvidia | 01:18 |
| lilstevie | AmEv: but if you were to compare the device to a dev board it would be closer to ventana | 01:18 |
| AmEv | Hmmm... | 01:19 |
| lilstevie | the a500 and the tf101 are almost identical, and the tf201 is almost identical in hardware and config to ventana (except the display) | 01:20 |
| lilstevie | er | 01:20 |
| lilstevie | s/tf201/tf101/ | 01:20 |
| lilstevie | been doing too much work on the later one :p | 01:20 |
| AmEv | I know people have been runing Ubuntu on their Transformers for a while... | 01:21 |
| AmEv | Lemme see if I can snag the dev in here.... | 01:21 |
| AmEv | Nope. | 01:21 |

| marvin24 | netchip: mkinitramfs? | 11:22 |
| marvin24 | the question which plagues me is if it can be used on a forgein arch (e.g. x86_64) to generate an arm version | 11:30 |
| marvin24 | or do I need to use some changeroot and qemu? | 11:30 |
| netchip | AFAIK you can | 11:32 |
| netchip | BTW | 11:32 |
| netchip | marvin24, https://wiki.ubuntu.com/ARM/RootfsFromScratch | 11:32 |
| marvin24 | yes, will try it out | 11:39 |
| netchip | hum | 11:40 |
| netchip | how to test if my network connection is OK? | 11:40 |
| marvin24 | I was just wondering if I need to emulate the whole cpu or just use a dir with an arm filesytem | 11:40 |
| marvin24 | netchip: ping? | 11:40 |
| netchip | marvin24, isn't installed... | 11:41 |
| marvin24 | ifconfig | 11:41 |
| marvin24 | route ... | 11:41 |
| netchip | also nopt installed | 11:42 |
| netchip | how to install without internet connexction? | 11:42 |
| marvin24 | dpkg has a "chroot" option | 11:42 |
| marvin24 | also make sure to fill /etc/resolv.conf | 11:43 |
| netchip | hmm | 11:44 |
| netchip | marvin24, do you know how I can get my WiFi on my phone work (a SGS3 running Ubuntu, BCM4334)? | 11:45 |
| netchip | just installing linux-firmware? | 11:45 |
| netchip | and then some conf files? | 11:45 |
| netchip | LMAO | 11:47 |
| marvin24 | best is to configure it on the phone once it is installed | 11:47 |
| netchip | yeah | 11:47 |
| netchip | it's checking if it's enabled | 11:47 |
| netchip | if not | 11:47 |
| netchip | enable it | 11:47 |

| marvin24 | oh, rootstock is depricated ... | 11:55 |
| marvin24 | fetching some pre-build image and adjust it seems the way to go now | 11:56 |
| netchip | well | 12:02 |
| netchip | how do they generate the prebuilt image? ;-) | 12:02 |

| zoktar | anyone here who can help me with multirom with kexec im not sure how i install kexec to make it work. It seemed to install correctly from recovory, but loading ubuntu rom says i havnt installed kexec. | 20:44 |
| zoktar | owh its for the nexus 7 | 20:45 |
| tassadar_ | what exactly have you flashed in the recovery? | 20:47 |
| tassadar_ | gimme name of that ZIP file | 20:47 |
| zoktar | the kexec? its the 4.2 one | 20:47 |
| zoktar | kernel_kexec_42.zip | 20:47 |
| tassadar_ | okay, go to multirom menu, try to boot ubuntu (the "you don't have kexec" message must pop out), the go to the "Misc" part and select "Copy log to /sdcard" | 20:48 |
| tassadar_ | reboot to recovery then and "adb pull /data/media/0/multirom/error.txt" | 20:49 |
| zoktar | alright will that show me the error log? | 20:50 |
| tassadar_ | it will save it to your computer, upload it to pastebin and show it to me :) | 20:50 |
| zoktar | ah alright cool | 20:50 |
| zoktar | thanks | 20:50 |
| zoktar | tassadar_, seemed i hadnt installed the kernel correctly. working fine now thanks. | 23:16 |
| tassadar_ | okay, great | 23:17 |
