| * paulsherwood has built a Jetson system with Docker on it... question is how/where to deploy it... | 12:02 | |
| pedroalvarez | paulsherwood: don't you have 2? | 12:40 |
|---|---|---|
| paulsherwood | not here. i'm at home | 12:40 |
| * paulsherwood will probably drive to jetson central soon... | 12:41 | |
| pedroalvarez | paulsherwood: afaik Jetson boards are upgradeable. So you could use that to deploy to the same board | 12:42 |
| paulsherwood | i've never tried that... i wonder if it's dangerous? :) | 12:42 |
| pedroalvarez | paulsherwood: dangerous enough to have fun ;) | 12:43 |
| paulsherwood | :-) | 12:43 |
| pedroalvarez | I have no idea if it's going to work in your board, sorry | 12:43 |
| paulsherwood | the instructions for how to deploy a self update are on the wiki somewhere, i'm sure of it... | 12:44 |
| * paulsherwood finds them at http://wiki.baserock.org/devel-with/#index7h2 | 12:45 | |
| pedroalvarez | There is an cluster example in definitions.git and I believe it has some instructions inside | 12:47 |
| paulsherwood | yes. it must be me, but those instructions seem rather unfriendly, and make me fear that i'll kill the machine | 12:49 |
| paulsherwood | thanks, though :) | 12:50 |

| radiofree | paulsherwood: you could upgrade pris from your vm | 15:16 |
| paulsherwood | i was just thinking about you, radiofree :) | 15:16 |
| radiofree | i sent pedro a cluster yesterday, hold on | 15:17 |
| radiofree | hmm you built it on the board though? | 15:17 |
| paulsherwood | i'm working on a noddy guide to starting on jetson - could you take a look? http://wiki.baserock.org/guides/baserock-jetson/ | 15:18 |
| radiofree | looks good | 15:19 |
| paulsherwood | 1750073344/4294967296 in 30 mins... the usb flashing is very slow | 15:19 |
| * paulsherwood hopes it's actually flashing properly | 15:19 | |
| radiofree | that is slow, my machine is a much faster then that oO | 15:20 |
| paulsherwood | i'm on a mac, vbox | 15:20 |
| paulsherwood | my objective is minimal instructions to do this from within baserock if possible | 15:21 |
| radiofree | oh so you're running the flashing util inside a baserock vm? | 15:22 |
| paulsherwood | yup | 15:22 |
| radiofree | you'd be much better off doing this flash http://wiki.baserock.org/guides/jetson/#index4h1 | 15:22 |
| radiofree | directly to the emmc, with u-boot | 15:22 |
| radiofree | i doubt this one you're about to flash will boot... | 15:22 |
| paulsherwood | really? why? | 15:22 |
| radiofree | every time you use ./flash.sh it will flash the old kernel again | 15:23 |
| paulsherwood | ah | 15:23 |
| paulsherwood | ok | 15:23 |
| paulsherwood | i guess i can just kill this then :) | 15:23 |
| radiofree | if you tell it to flash the kernel in this rootfs it won't work either, since it will have a different device tree | 15:23 |
| radiofree | paulsherwood: you can leave it | 15:23 |
| radiofree | it's very quick to just flash the kernel again afterwards | 15:24 |
| radiofree | KERNEL_IMAGE=~/path/to/kernel ./flash.sh -k 6 jetson-tk1 mmcblk0p1 | 15:24 |
| radiofree | follow the flash step i just linked instead | 15:24 |
| radiofree | that will install u-boot so you won't have this problem again | 15:24 |
| paulsherwood | ok | 15:25 |
| paulsherwood | i'll need to digest your instructions - they're still too expert for me :) | 15:25 |
| radiofree | did you deploy your docker image as a rawdisk? | 15:27 |
| radiofree | download http://download.baserock.org/baserock/tegra/baserock-jetson-flash.sh into your Linux_for_Tegra folder | 15:27 |
| paulsherwood | this is not docker, yet. i'm just trying to solve devel on jetson, no external drive | 15:27 |
| radiofree | ah | 15:28 |
| paulsherwood | no distbuild | 15:28 |
| paulsherwood | so are you saying i could just use your baserock-jetson-flash.sh instead of the nvidia one? | 15:29 |
| paulsherwood | given the rootfs i've stuck in the Linux_for_tegra folder is baserock, how is it going to get the wrong kernel etc? | 15:30 |
| radiofree | it calls the nivida flashing tool | 15:30 |
| radiofree | fastboot doesn't load the kernel from the rootfs, you flash that to the emmc somewhere (partition 6 i think...) | 15:31 |
| radiofree | https://github.com/NVIDIA/tegra-uboot-flasher-scripts/blob/master/README-user.txt | 15:31 |
| paulsherwood | ok | 15:31 |
| radiofree | we could package this up i think | 15:31 |
| paulsherwood | that's what i'm trying to do :-) | 15:31 |
| radiofree | hmm i wrote some instructions for that | 15:32 |
| paulsherwood | i don't mean to criticise, but your instructions are too hard for me :-) | 15:32 |
| paulsherwood | i'm a mac user, after all | 15:33 |
| * paulsherwood wishes, not for the first time, that our devel images were stripped to be as small as possible | 15:35 | |
| radiofree | http://fpaste.org/126046/03354140/ | 15:35 |
| radiofree | this has a few problems, you actually have to build u-boot with this | 15:35 |
| radiofree | however it *is* possible to tell tegra-uboot-flasher-scripts to use a pre-built image | 15:36 |
| radiofree | it would be possible to put these things together and say "just run this command to setup u-boot for baserock" | 15:36 |
| paulsherwood | could i follow those instructions in baserock? | 15:38 |
| paulsherwood | they mention CROSS_COMPILE | 15:38 |
| radiofree | yeah that's because these instructions actually build u-boot | 15:39 |
| radiofree | these are instructions i did for outside baserock, i.e to flash it | 15:39 |
| radiofree | flash the board | 15:39 |
| paulsherwood | yes, ok | 15:39 |
| radiofree | however you can tell it to use a pre-built u-boot.img, so you wouldn't have to build u-boot | 15:40 |
| radiofree | u-boot is in the jetson releases /boot folder | 15:40 |
| radiofree | i don't have a jetson so i can't test any of this atm | 15:40 |
| paulsherwood | ok, no problem, thanks for the guidance | 15:40 |
| paulsherwood | radiofree: i believe it has booted | 15:54 |
| paulsherwood | now i just can't log in to the damn thing :) | 15:54 |
| radiofree | oh yeah, the default fast boot parameters disable the serial login.... | 16:00 |
| paulsherwood | i'm in :) | 16:06 |
| paulsherwood | (hdmi cable and usb keyboard) | 16:07 |
