vmrod25hi team question , how do I set up the boot args on the minnow ? I used to do that in grub not sure if is the same on minnow ( i am a little bit tired of type fs0: and bootx64 )15:24
vmrod25( BTW I am ussing yocto )15:25
warthog9vmrod25: if you just want to change the boot order you can do that in the firmware15:25
*** programmerq <programmerq!~jefferya@unaffiliated/programmerq> has quit IRC15:25
bcranvmrod25: via the firmware/BIOS setup, just like a PC15:25
vmrod25thanks warthog9 and bcran .. do we have a wiki for that ?15:26
dememorizedwarthog9: is the person who develops the minnowboard.org website european?15:26
bcranvmrod25: I don't think so - it's a fairly standard procedure though15:26
warthog9dememorized: define "develops"15:27
*** programmerq <programmerq!~jefferya@unaffiliated/programmerq> has joined #minnowboard15:27
warthog9vmrod25: it's a little old but http://elinux.org/Minnowboard:MaxBios#Boot_Maintenance_Manager15:27
dememorizedwarthog9: haha, http://www.minnowboard.org/where-to-buy/ git blame on the z/li> :P15:27
warthog9dememorized: the correct answer is me *hangs head in shame*15:28
dememorizedwarthog9: Haha, you're using a ISO keyboard?15:28
warthog9dememorized: should be fixed15:29
dememorizedwarthog9: is fixed :(15:29
warthog9and no, US keyboard, but the m key is right next to the < so I must have fat fingered it at some point15:30
dememorizedwarthog9: but didn't it say z?15:30
dememorizedand z is right next to the < key on ISO-keyboards15:30
warthog9dememorized: said m on my screen...15:31
meflinwrong hand typing syndrome15:31
warthog9dememorized: no you are right15:31
warthog9was a z15:32
dememorized*phew* Was starting to worry about the sanity of languages in general15:32
warthog9no idea how I got z there other than random neural miss-firing15:32
meflinkeystroke in wrong hand15:32
vmrod25thanks a lot warthog915:33
warthog9vmrod25: no problem, if you need a more explicit step-by-step, let me know and I'll add it to the wiki15:34
vmrod25sure .. :)15:34
warthog9though I don't have a minnow in front of me right this second as I'm sitting around waiting for plumbers15:35
bcranwarthog9: just noticed the "Where to buy -> Expansion Boards (Lures)" page seems a bit sparse. Should it link to Minnowboard:MaxLures on elinux.org now instead of minnowboard.org/expansion-2 ?15:35
vmrod25warthog9: LOL15:36
warthog9vmrod25: plight of having just bought a house, I'm trying to fix all the things15:36
vmrod25well I have some minnows .. working on the opencv + minnow + webcam + MPI + galileo15:36
warthog9nice15:37
vmrod25warthog9: been there done that .. remember 2 years ago when I was in the same situation . .but hey congrats dude15:37

warthog9got the rack into it's space last night too15:38
* bcran is currently selling his apartment in the UK, to hopefully get some money to buy a place in the US15:38
vmrod25bcran: If I could I woudl be more than happy to buy that apartment15:38
* vmrod25 loves UK15:38
bcranbtw if people didn't see the email on edk2-devel, I've started putting some UEFI/MinnowMAX pages onto a wiki at https://edk2.bluestop.org/w/15:39
vmrod25nice I will need that15:39
bcranvmrod25: you're welcome to it - I'm glad to have left Scotland with its miserable weather! :)15:39
vmrod25there is a bug with opencv and webcam15:39
vmrod25I can see with lsusb the webcam15:40
vmrod25and dmesg shows me : http://pastebin.com/HXc2gm3s15:41

vmrod25btw warthog9 how do you make yocto image lives in a SATA15:56
vmrod25?15:56
warthog9vmrod25: i assume you are using the mkefidisk script?15:57
vmrod25I mean in the end this minnow will be the server but they will need a hard driver15:57
vmrod25yes15:57
* vmrod25 loves that libtle script15:57
warthog9it's "good" though the whole mess is complex15:57
warthog9so from a Linux perspective the sata will be treated as an /dev/sd* devices15:57
warthog9so you'll want to write it out to a /dev/sd and *LIKELY* /dev/sda for the boot device15:58
vmrod25so .. let me see if I understand .. I first boot in my sd card then I copy the image to the sdcard with the script and run the script pointing to /dev/sda ?15:59
*** metastableB_ is now known as metastableb16:06
warthog9vmrod25: assuming you boot from an sd card and you are running mkefidisk on the target host16:07
warthog9then, yes, you will want to write to /dev/sd* (where * is the sata device) and you'll want to make the boot drive /dev/sd* as well16:07
warthog9brb going to go deal with something in the attic16:11
vmrod25ok got it warthog916:13

dvhartvmrod25, is it USB?17:58

vmrod25let me show you the lsusb and dmesg18:00
*** jnavarro <jnavarro!c713fb3e@gateway/web/freenode/ip.199.19.251.62> has quit IRC18:01
dvhartand do you have the appropriate driver loaded for it? Does the kernel recognize it?18:02
vmrod25dvhart: http://pastebin.com/vMwADjED18:04
warthog9vmrod25: you on yocto or a normal distro?18:04
vmrod25is not guaranty that if lsusb detects it the kernel did18:04
vmrod25warthog9: yocto18:05
warthog9vmrod25: it's possible that you don't have the right driver compiled into the kernel itself18:05
vmrod25the bb file and local.conf are here : https://github.com/VictorRodriguez/opencv_tutorial/tree/master/yocto-conf18:05
vmrod25let me double check the make menuconfig18:06
dvhartlsusb can provide details of the device, including vendor product IDs without a kernel driver (same as lspci for PCI devices).18:06
dvhartYou still need the right kernel driver.18:06
dvhartYou can verify you have the right kernel drvier by ensuring it lists the vendor product IDs in it's match table18:06
vmrod25thanks for the clarification dvhart18:07
vmrod25how do I do that part ?18:07

dvhartvmrod25, I usually grep the kernel sources if it isn't obvious which driver to check18:09
vmrod25you are right dvhart, when I plug the same webcam to my fedora I got this message http://pastebin.com/E5ebczdQ18:15
vmrod25so yea there is a missing driver18:15
dvhartLooks like uvcvideo is the right driver18:16
dvhartand it's failing to load18:17
dvhartHave a look at that driver and see if it has the vendor product ID in the match table18:17
vmrod25yea .. looks like that18:20
vmrod25thanks dvhart18:20
