GPSFanprpplague, a funny little fish swam out of the UPS truck yesterday and is flopping around on my desk... ;>)15:23
prpplagueGPSFan: dandy!15:24
prpplagueGPSFan: first things firsts15:24
prpplagueGPSFan: once you get linux up and running can you check to make sure the nic has a mac address?15:24
GPSFanprpplague, got a few questions and comments. the hole size for the mounting holes seems a bit big ie #6 whereas the pad looks like it is sized for a #4.15:25
hrwthat reminds me that I need to go to store and buy some AA batteries for my wireless keyboard.15:25
prpplagueGPSFan: yea, found that one too late on this set of boards15:25
prpplagueGPSFan: the whole was originally was #4 and we changed it to #6 and the pads didn't get updated15:26
thaytanworldwide recall!15:26
GPSFanprpplague, when I power it up I get a map file not found on the UEFI screen.15:26
GPSFanno boot device connected15:26
GPSFanthe pix of that screen on the elinux wiki show a lot of other stuff printed before it drops to the shell prompt.15:27
*** jbdatko <jbdatko!~jbdatko@fsf/member/jbdatko> has quit IRC15:27
*** jbdatko <jbdatko!~jbdatko@fsf/member/jbdatko> has joined #minnowboard15:28
GPSFanprpplague, I also looked at the board under a microscope and am seeing what looks like vias being way to close (touching) to signal traces.   since the board powers up I guess that isn't so.15:29
GPSFanprpplague, once I figure out the whole UEFI stuff I'll check out the MAC address issue15:30
prpplagueGPSFan: yea i think those vias are on different layers15:30
prpplagueGPSFan: let me check those on the gerbers15:30
* GPSFan hasn't done x86 bios stuff for years15:31
prpplagueGPSFan: i am not seeing those vias looking like that on any of the other boards15:44
prpplagueGPSFan: i'm going to look at the solder samples from the same lot of pcbs to see if there was an issue15:45
prpplagueGPSFan: if you can get some more pictures of that , it would be helpful15:45
GPSFanprpplague, well I looked closer: the serpentine trace to the left of c124 & C134  has a pad that is on the top layer and looks to be very close to the trace just to its left.15:47
GPSFanprpplague, I'll take a better pix in a few minutes.15:47
prpplagueGPSFan: yea, we are checking now15:48
hrwprpplague: mac address can be faulty?15:50
hrwprpplague: here it worked15:50
prpplaguehrw: give me a minute and i'll tell you about it15:58
prpplagueGPSFan: ok, so i just checked15:58
prpplagueGPSFan: the board house made some changes to gerbers on one set15:59
prpplagueGPSFan: looks like the board you have was from one of the pre-production run15:59
prpplagueGPSFan: there were only about 50 made from that batch of pcbs15:59
prpplaguehrw: looks like one of the test station girls was interrupting the automated tests on a few boards16:01
prpplaguehrw: and running the tests manually16:01
prpplaguehrw: part of the test sequence is to flash the mac address16:02
prpplaguehrw: so it looks like there might be about 20 to 30 boards out there without a hardcoded mac16:02
hrwprpplague: be back in 2-3h16:02
GPSFanprpplague, here is a better pix    not as hi res as before, but this is my old Agfa camera that has the closeup lens set.16:06
*** sjolley <sjolley!sjolley@nat/intel/x-odoxagmecfffdfwm> has quit IRC16:07
prpplagueGPSFan: yea, double checked16:14
prpplagueGPSFan: that board is from the pre-production run16:14
GPSFanprpplague, oh yeah, that's far better! will that be an issue on my board? I guess it passes QC test so I wouldn't think so.16:16
*** Zerb1 <Zerb1!3f930a03@gateway/web/freenode/ip.> has joined #minnowboard16:18
prpplagueGPSFan: i would not expect it to be an issue since it was electrically tested and passed QC16:19
prpplagueGPSFan: if you do find something let me know and we'll swap it out16:19
prpplagueGPSFan: the joys of getting a new product up to full speed16:19
GPSFanprpplague, glad to hear. any idea on the "required map file not found"16:19
prpplagueGPSFan: depends on what you are trying to accomplish16:22
GPSFanprpplague, "map: Cannot find required map name" is the actual message16:22
prpplagueGPSFan: that just means that the UEFI firmware did not find any bootable media16:23
GPSFanprpplague, this when I first powered it up, I'm maybe 10 minutes into fiddling with it and that screen didn't match what the wiki had.16:23
GPSFanprpplague, ah, that's good then I'll shut up now ;>)16:23
prpplagueGPSFan: i'll get warthog9 to add that to the wiki16:23
* prpplague makes a notes16:23
*** sjolley <sjolley!~sjolley@> has joined #minnowboard16:31
warthog9prpplague: for a minute I thought you were telling me to add GPSFan to the wiki, I was a little confused16:42
prpplaguewarthog9: hehe16:43
*** nashi <nashi!~Jaqie@> has joined #minnowboard16:47
prpplagueok everyone... if you have recently received your minnowboard max, please double check to see if it has an assigned mac address!17:01
*** nashi <nashi!~Jaqie@> has quit IRC17:03
holtmannprpplague: How do we tell? Is the driver generating a random one or does every board has the same static one?17:04
prpplagueholtmann: when you boot into linux, you should be able to just do: ifconfig -a17:07
prpplagueholtmann: the eth0 interface should not have all zeros for mac17:07
holtmannSome drivers just generate a mac in that case.17:07
prpplagueholtmann: the driver should not generate one17:08
prpplagueholtmann: this specific one is not configured that way by default17:08
holtmann  001320     (base 16)Intel Corporate17:09
holtmannHah. We are using an Intel OUI.17:09
holtmannMine boots at least with the same address. So I bet it is configured.17:09
prpplagueholtmann: yea intel provided the macs as a donation to minnowboard.org17:11
holtmannHope is one of our ranges that are not used by any other group ;)17:12
prpplagueholtmann: nope it was specifically allocated for minnowboard.org17:12
ahollerI still wonder why MACs are still that short. I remember times when some companies thought about buying back old cards just to get MACs back17:13
prpplagueaholler: not really short in qty, it;s more of a cost/paperwork issue17:14
*** dvhart <dvhart!~dvhart@> has quit IRC17:14
ahollerat that time they talked about running out of MACs without getting more17:15
prpplagueholtmann: one of the test station operators was interrupting the automated validation tests and restarting it manually17:15
prpplagueholtmann: which i did not consider when writing the validation framework, hehe17:15
holtmannAnd we are still able to assign the same IEEE address to Bluetooth and WiFi. So can't be all that bad.17:15
prpplagueaholler: yea, the "not getting any more" was more about the money and paperwork. there were doing a lot to ration the blocks and such17:16
ahollerwas 3com or similar if I remember correctly. But maybe they just had some bureaucrazy problem with the master of the MACs at that time ;)17:16
prpplagueaholler: but you can generally get a sizable block know for less than $1k17:17
prpplagueaholler: indeed17:17
ahollerbut I assume they now just share macs across countries or continents17:23
prpplagueaholler: and you can file a request to reuse the mac addresses a certain number of times17:24
prpplagueaholler: basically you have to do a calculation on the probablity of having two devices with the same mac on the same network17:25
GPSFanprpplague, my board has nothing populated for SW1, can I add a switch or is there a GPIO issue?17:34
prpplagueGPSFan: pfft17:38
prpplagueGPSFan: are you serious?17:38
prpplagueGPSFan: we normally have a pile of boards from the pre-production that we recycle for testing and such17:39
prpplagueGPSFan: i am guess someone in shipping saw that i said this was for eval and they grabbed one from that pile17:40
prpplagueGPSFan: i'll make arrangements to get one of the regular production out to you17:40
GPSFanprpplague, not really I thought that if it wasn't populated that it might be connected to something that might smoke the board when pressed... ;>)17:40
prpplagueGPSFan: (which explains why you have the older pcb)17:40
GPSFanprpplague, no no I want to see the smoke...17:41
prpplagueGPSFan: no it should be populated17:41
prpplagueGPSFan: guess today is that "critical mass" date when enough boards are out there to see the little issues with the production process17:42
GPSFanprpplague, so far it looks like a fine piece of kit.17:43
warthog9GPSFan: :-)17:52
prpplagueGPSFan: thanks!17:53
warthog9ok since I'm in front of the correct computer now, what was I adding to the wiki for GPSFan?17:53
prpplagueGPSFan: still working out the kinks in getting production to where we want it to be without any issues.... such as missing mac17:54
prpplaguewarthog9: messages to expect when there are no bootable devices17:54
warthog9just need a "screen shot" of what it looks like?17:54
* warthog9 will probably pull it from the serial console17:54
prpplaguewarthog9: that's what i was just typing17:54
warthog9prpplague: I see our telepathy is developing17:55
warthog9explains all the headaches I've had lately ;-)17:55
*** dvhart <dvhart!~dvhart@> has joined #minnowboard17:55
GPSFanwarthog9, just a note that if you get a "map: Cannot find required map name" message that there are no bootable devices connected ie no SD, no USB, no SATA17:56
warthog9I need to add the two commands to map in a device after you've hot plugged it to17:57
warthog9it's <something> -r;map -r17:57
warthog9dvhart would remember though17:57
warthog9connect -r ; map -r ?17:57
GPSFanI'm getting ready to install linux on a usb hdd now, I'll report any funny stuff.17:57
bluelightningso... I'm having a bit of trouble booting a poky image on our recently received max - should I expect to be able to build core-image-minimal, use to copy it to a USB flash drive and then boot from that?17:57
warthog9GPSFan: as long as it's not "why did the chicken run down the side of the highway?" me: "don't know but there's a feather plume just ahead"17:58
warthog9bluelightning: that should work, I assume you are building 64-bit?17:58
prpplaguebluelightning: yes it should17:59
warthog9and what problems is it giving you?17:59
GPSFanwarthog9, naw, the chickens all went to the freezer last week.17:59
bluelightningwarthog9: yes, intel-corei7-6417:59
prpplaguebluelightning: we now have a wiki page up for info on how to do the builds17:59
warthog9bluelightning: specifically18:00
bluelightningwarthog9: prpplague: thanks18:00
bluelightningto be more specific it drops me into the EFI shell instead of booting automatically, and when I run the bootx64 EFI executable manually, grub does start but when I select the "boot" item, I get a few kernel messages and then it freezes18:00
prpplaguewarthog9: need to add that link to the resources on the main wiki page as well18:00
warthog9bluelightning: would be useful to get those messages, kinda hard to debug without them18:01
warthog9and make sure that you boot sans quiet or plymouth on the kernel command line18:01
prpplaguewarthog9: don't forget we also need to document how to verify the version of UEFI firmware for max18:02
warthog9it's on my todo list18:03
bluelightningwarthog9: they aren't particularly informative:
warthog9bluelightning: you almost assuredly have quiet turned on on the kernel boot line18:07
warthog9but that indicates you are booting fairly far18:07
prpplaguedvhart: doesn't the core image only provide a serial console?18:07
* prpplague tries to remember18:07
bluelightningwarthog9: right, that is apparently the default18:07
bluelightningI've just turned that off, there's definitely a lot more as you'd expect but it stops at the same place18:08
warthog9bluelightning: yeah, it's a default I grind my teeth over, but I understand why it's the default18:08
warthog9anything about not being able to find the root?18:08
bluelightningoh wait18:09
bluelightningI have been an idiot and told the wrong device18:09
bluelightningsorry for the noise18:09
prpplaguebluelightning: hehe18:09
prpplaguebluelightning: yes that should report a kernel panic for not being able to mount the right device18:10
prpplaguebluelightning: for a single thumb drive, it should be /dev/sda18:10
bluelightningprpplague: right, perhaps the timeout is long and I just didn't wait long enough18:10
bluelightningprpplague: indeed18:10
warthog9prpplague: it's probably stalling trying to wait for the device to appear18:11
prpplaguewarthog9: yea18:11
warthog9right what bluelightning said :-)18:11
GPSFanhere is an interesting quirk, the UEFI Shell has a nice help system ie type help reconnect and you get a lovely man page like screen. Only problem is when the text is longer than the internal scrollback buffer. such as: help map.18:12
* dvhart returns and reads back18:12
prpplaguedvhart: nm18:12
prpplaguedvhart: resolved18:12
prpplagueGPSFan: yea18:12
warthog9prpplague: well one of the issues pinged him on was resolved ;-)18:13
prpplagueGPSFan: root cause - the screen formating is designed to work for hyperterminal18:13
prpplagueGPSFan: (assuming you are using the uart)18:13
bluelightningaha, now it boots :)18:14
GPSFanprpplague, I figured as much, I've got it plugged into an hdmi display.18:14
warthog9bluelightning: \o/18:14
bluelightninghowever, still doesn't seem to boot automatically - is that expected?18:14
dvhartmkefidisk seems to trip people up rather frequently18:14
dvhartbluelightning, any suggestions on how to make it more obvious?18:14
prpplaguebluelightning: yea there are tweaks and things that have to be done to get it to boot directly every time18:14
dvhartdoes my description in the URL above for elinux help any?18:14
bluelightningwould help if I read it, which I'm about to do :)18:14
dvhartto be fair it didn't exist until yesterday18:17
bluelightningI'm using master FWIW18:18
bluelightningI did have a couple of other problems with mkefidisk18:18
bluelightningboth of which stemmed from me trying to use a USB key that had a Fedora live image on it previously18:18
bluelightningparted threw up a bunch of prompts when first accessing it, which meant that the script hangs; I have a fix for that18:19
bluelightningthe second which I didn't look into is that something doesn't get cleared on the USB key which means that you get the Fedora live grub config instead of the one that should be used18:20
dvharthrm... I've a couple of those things sporadically and have put in a fix here and there, but they keep cropping up.18:23
dvhartseems it is sensitive to the content of the disk in ways I haven't yet identified :/18:23
bluelightninghmm, having an issue with ethernet as well: SIOCSIFFLAGS: Cannot assign requested address18:26
prpplaguebluelightning: once you are logging in18:27
prpplaguebluelightning: check with ifconfig18:27
prpplaguebluelightning: to see if you have a mac address18:27
prpplaguebluelightning: ifconfig -a18:27
bluelightningprpplague: ah... none listed, that might cause issues18:27
prpplaguebluelightning: send me an email to danders@circuitco.com18:27
prpplaguebluelightning: i'll send you some info on how to assign one18:28
carpmanconfuse people running arpwatch ;)
bluelightningprpplague: sent, thx18:29
bluelightningdvhart: I was going to suggest using the label on the kernel command line rather than the device, but I just tried that and it doesn't seem to work18:59
