**** BEGIN LOGGING AT Wed Mar 25 02:59:57 2020
Mar 25 03:00:31 <GenTooMan> ds2 Amazon is having delivery "issues" and they are 30+ days behind.
Mar 25 03:08:43 <set_> I have an endoscope showing up for the first.
Mar 25 03:09:08 <set_> I am going to stick it in and watch this pipe inspection take place but first...
Mar 25 03:09:12 <GenTooMan> set_ you could use an IOgear USB port extender to get you 198 feet if you want. Though I suspect the end device will want to be self powered.
Mar 25 03:09:43 <set_> I need to find a auger cabling big enough to fit my endoscope in it.
Mar 25 03:09:51 <set_> Good luck to me!
Mar 25 03:10:40 <set_> Auger cabling is so expensive.
Mar 25 03:10:53 <set_> Now, my bbb is lonely. Dang it!
Mar 25 03:11:29 <set_> ds2: You got me sold on cheap devices instead of using the BBB. It would have been a nice write up too.
Mar 25 03:11:41 <set_> i.e. hackster.io or hackaday.io.
Mar 25 03:12:26 <set_> GenTooMan: You are right. I found many alternatives but I did find the USB extension cable for cheap from MonoPrice.
Mar 25 03:14:47 <set_> I guess unless I was some wizard w/ knowledge of meter-depth, waterproofing, my end tool might end up soaked and broken.
Mar 25 03:15:55 <set_> I guess looking up volume of water under one meter and the effect of gravity on that above water would be wise on my part if I do end up using the BBB for this task.
Mar 25 03:17:03 <set_> Ha.
Mar 25 03:17:12 <set_> I found NEMO: https://www.pmel.noaa.gov/eoi/nemo1998/education/pressure.html.
Mar 25 03:19:58 <set_> That is interesting. I always wondered what happened to the people making subs w/ their BBBs.
Mar 25 03:20:27 <GenTooMan> Just do some simple calculations of pressure. Doesn't take much 3 meters you can really feel. :D
Mar 25 03:22:06 <set_> Right. So, 14.6" of pressure is about all I need to account for unless I go over 10 meters deep?
Mar 25 03:24:16 <set_> 14.6 is the lbs. per square inch of pressure.
Mar 25 03:26:24 <set_> Albeit interesting, I never really thought much about it. So, for every 10 meters of depth, one atmosphere is pressed against our bodies in water.
Mar 25 03:26:25 <set_> Neat.
Mar 25 03:26:55 <set_> One atmosphere is the 14.6 lbs. per square inch of pressure.
Mar 25 03:27:24 <set_> Boing! Wozzers. That poor bbb. All that pressure and nowhere to turn.
Mar 25 03:29:58 <set_> https://www.sofarocean.com/ <<< I think this is what happened to openROV.
Mar 25 03:30:28 <set_> Nice.
Mar 25 03:46:57 <MattB0ne> I am trying to have the beagle access Internet through my laptop ethernet
Mar 25 03:47:15 <MattB0ne> I went and shared my connection on my laptop
Mar 25 03:47:50 <MattB0ne> now I am supposed to set ipv4 to auto and ipv6 to ignore
Mar 25 03:47:56 <MattB0ne> how do I do that?
Mar 25 03:47:59 <MattB0ne> ifconfig?
Mar 25 03:48:11 <zmatt> you shouldn't need to set anything
Mar 25 03:48:16 <zmatt> what makes you say you're "supposed to"
Mar 25 03:50:56 <zmatt> does your beaglebone still not have an ip address?  what does "ip addr show eth0" show?  if you enabled internet sharing while ethernet was connected, try unplugging it, waiting a second, and plugging it back in
Mar 25 04:04:09 <mastermind_> zmatt:https://pastebin.com/embed_js/xPYvkHxj
Mar 25 04:04:25 <mastermind_> Zmatt: it is MattB0ne
Mar 25 04:04:33 <zmatt> "Error, this is a private paste"
Mar 25 04:06:02 <mastermind_> https://pastebin.com/embed_js/HRXHKPWi
Mar 25 04:06:06 <mastermind_> how about now
Mar 25 04:07:01 <MattB0ne> i do not think i have an ip address
Mar 25 04:07:10 <MattB0ne> i know nothing about this stuff
Mar 25 04:07:13 <MattB0ne> though
Mar 25 04:07:20 <zmatt> you could also just have changed it from private to unlisted... also why are you giving javascript embedding links instead of normal ones?
Mar 25 04:07:34 <zmatt> yeah it means you didn't get an ip
Mar 25 04:07:51 <zmatt> this is after enabling internet sharing?  have you tried unplugging it, waiting a second, and plugging it back in?
Mar 25 04:07:54 <MattB0ne> first time using pastebin I could not find the link
Mar 25 04:08:06 <zmatt> it's just the url of the page you get
Mar 25 04:08:49 <MattB0ne> does it matter that I am sharing my wifi?
Mar 25 04:08:59 <zmatt> anyway, an IP address that starts with "169.254." is a self-assigned address that may be used when there's no dhcp server found on the network
Mar 25 04:09:46 <zmatt> you need to have internet sharing enabled yes, that was the whole point behind this
Mar 25 04:10:32 <MattB0ne> right that is the one I shared
Mar 25 04:10:41 <MattB0ne> went into network settings under IPv4
Mar 25 04:10:44 <MattB0ne> set to share
Mar 25 04:10:51 <MattB0ne> set IPv6 to ignore
Mar 25 04:11:00 <MattB0ne> made sure could share with all c omputers
Mar 25 04:11:20 <zmatt> why are you changing IPv6 settings?
Mar 25 04:11:59 <MattB0ne> I was having problems with my router and turning that stuff off seemed to help
Mar 25 04:12:05 <MattB0ne> so I just shut it off
Mar 25 04:12:30 <MattB0ne> something with the dhcp
Mar 25 04:12:49 <MattB0ne> was causing my i can put it back
Mar 25 04:12:53 <MattB0ne> and share both I guess
Mar 25 04:14:31 <MattB0ne> when I do that I lose the self assigned ip address
Mar 25 04:18:10 <zmatt> if you can't get internet sharing to work, an alternative thing you can try... disable internet sharing, select both interfaces (wifi and ethernet), right click and select Bridge Connections: https://www.thewindowsclub.com/ezoimgfmt/thewindowsclub-thewindowsclubco.netdna-ssl.com/wp-content/uploads/2013/05/Create-a-Network-Bridge-in-Windows.jpg
Mar 25 04:18:34 <zmatt> theoretically this shouldn't be possible, but I know it has worked for me in the past
Mar 25 04:19:33 <MattB0ne> ok I will give it a shot
Mar 25 04:19:40 <MattB0ne> Windows does not give me problems
Mar 25 04:19:44 <MattB0ne> just mint
Mar 25 04:19:51 <zmatt> mint?
Mar 25 04:19:51 <MattB0ne> must be a permission thing or something
Mar 25 04:19:58 <zmatt> oh I assumed you were using windows for some reason
Mar 25 04:19:59 <MattB0ne> mint linux distro
Mar 25 04:20:31 <MattB0ne> I go back and forth, I was on a windows box when I was getting the TTL thing working because the config tool that came with the controller was windows only
Mar 25 04:20:43 <MattB0ne> I am trying to do everything in linux now
Mar 25 04:20:46 <MattB0ne> I started off with arch
Mar 25 04:20:54 <MattB0ne>  but got too frustrated
Mar 25 04:20:59 <MattB0ne> so moved to mint
Mar 25 04:21:21 <MattB0ne> i kept breaking my system every update with arch
Mar 25 04:21:26 <MattB0ne> got tired of it.
Mar 25 04:21:47 <zmatt> https://askubuntu.com/questions/359856/share-wireless-internet-connection-through-ethernet
Mar 25 04:21:55 <zmatt> I'm guessing the steps are similar on mint
Mar 25 04:22:05 <zmatt> (both probably use gnome network manager)
Mar 25 04:22:37 <zmatt> you shouldn't need to manually assign an ip address on the client computer though
Mar 25 04:22:44 <zmatt> the first comment also notes that
Mar 25 04:23:42 <zmatt> (the client in this case being the bbb)
Mar 25 04:30:55 <MattB0ne> ok I messed up my ssh
Mar 25 04:31:08 <MattB0ne> and I see three ethernets
Mar 25 04:31:33 <zmatt> I'm proud of you
Mar 25 04:31:36 <MattB0ne> lol
Mar 25 04:32:22 <MattB0ne> I power my board with the USB
Mar 25 04:32:34 <MattB0ne> so I have the ethernet and usb active at the same time
Mar 25 04:32:37 <MattB0ne> is that bad
Mar 25 04:33:29 <zmatt> no
Mar 25 04:33:45 <zmatt> that should not be a problem
Mar 25 04:35:15 <MattB0ne> so on my network submenu I have PCI Ethernet and two entries of Ethernet that have what my laptop name for my board
Mar 25 04:35:52 <MattB0ne> the difference between the two Ethernet entries is oen has a 192. IPv4 address
Mar 25 04:35:55 <MattB0ne> one does not
Mar 25 04:36:11 <zmatt> ?
Mar 25 04:36:33 <zmatt> oh yeah the BBB probably shows up as two usb network interfaces on linux
Mar 25 04:37:12 <MattB0ne> one has a DNS of 8.8.8.8
Mar 25 04:37:14 <MattB0ne> the other is blank
Mar 25 04:37:32 <zmatt> one RNDIS (which should assign your PC 192.168.7.1) and one CDC-ECM (which should assign your PC the address 192.168.6.1)
Mar 25 04:37:51 <zmatt> uhh, neither should have a DNS or default gateway unless something is seriously screwed up
Mar 25 04:38:15 <MattB0ne> I will just delete it then
Mar 25 04:41:07 <MattB0ne> i cannot ping 192.168.7.2
Mar 25 04:41:11 <MattB0ne> =(
Mar 25 04:43:04 <MattB0ne> ok restrated the board
Mar 25 04:43:06 <MattB0ne> can ssh
Mar 25 04:47:33 <MattB0ne> i think the beagle has an IP now
Mar 25 04:47:34 <MattB0ne> https://pastebin.com/QwKcWPkS
Mar 25 04:47:42 <MattB0ne> that  was run on the board
Mar 25 04:47:47 <MattB0ne> still cannot ping
Mar 25 04:48:00 <zmatt> maybe firewall on your pc?
Mar 25 04:48:42 <zmatt> (a sanely configured firewall shouldn't block internet access for other devices, but that may be assuming too much)
Mar 25 04:48:52 <MattB0ne> never set one up
Mar 25 04:49:03 <zmatt> by "still cannot ping" you mean you can't ping e.g. 8.8.8.8 from the beaglebone?
Mar 25 04:49:22 <MattB0ne> right
Mar 25 04:49:31 <MattB0ne> but I have an IP right?
Mar 25 04:49:35 <zmatt> yes
Mar 25 04:49:44 <zmatt> what does "ip route" show?
Mar 25 04:49:44 <MattB0ne> the ip addr should be run from the host or the beagle?
Mar 25 04:49:53 <zmatt> beagle
Mar 25 04:51:58 <MattB0ne> and the IPv4 and IPv6 should be set to auto
Mar 25 04:52:07 <zmatt> of what?
Mar 25 04:52:28 <MattB0ne> of the ethernet connecting the beagle and host
Mar 25 04:52:58 <zmatt> ?? you configured that to internet sharing right, how else would the beaglebone be able to get an ip?
Mar 25 04:53:31 <zmatt> the beaglebone has an ip address so I suggest not touching your setup
Mar 25 04:53:36 <zmatt> 05:49 <@zmatt> what does "ip route" show?
Mar 25 04:54:39 <MattB0ne> https://pastebin.com/4qFwAZ67
Mar 25 04:54:43 <MattB0ne> seems to go through my usb
Mar 25 04:55:00 <zmatt> why the fuck does usb0 have a default gatewya o.O
Mar 25 04:55:14 <zmatt> and why does ethernet not
Mar 25 04:55:17 <MattB0ne> man i dunno
Mar 25 04:55:29 <MattB0ne> i was putzing around with this
Mar 25 04:55:44 <MattB0ne> who knows what shennanigans i cause
Mar 25 04:56:01 <MattB0ne> i take it that is the problem
Mar 25 04:56:05 <zmatt> okay the default network setup of the beaglebone is out of the box clearly pretty broken... I personally never use rcn's startup scripts that setup usb, nor do I use connman
Mar 25 04:56:43 <MattB0ne> should I flash I was thinking of getting that new release client image anyway
Mar 25 04:56:57 <MattB0ne> if this is pretty FUBAR
Mar 25 04:57:15 <zmatt> I mean, you didn't change any network settings on the beaglebone right?
Mar 25 04:57:59 <MattB0ne> I made one change to get it to work with windows
Mar 25 04:58:09 <zmatt> being?
Mar 25 04:58:22 <zmatt> it shouldn't require any change to "work with windows"
Mar 25 04:59:12 <MattB0ne>  sudo /sbin/route add default gw 192.168.7.1
Mar 25 04:59:39 <zmatt> oh so you did break networking yourself
Mar 25 05:00:09 <MattB0ne> probably
Mar 25 05:00:17 <MattB0ne> can I just take out that route
Mar 25 05:00:20 <zmatt> although that doesn't explain why the one for ethernet is missing
Mar 25 05:00:37 <MattB0ne> i also may have done this
Mar 25 05:00:48 <zmatt> but, I'm kinda out of energy on this
Mar 25 05:01:11 <MattB0ne> https://pastebin.com/SRsrbCqw
Mar 25 05:01:15 <MattB0ne> understood
Mar 25 05:01:23 <zmatt> oh god what did you do
Mar 25 05:01:24 <MattB0ne> basically I will flash
Mar 25 05:01:26 <zmatt> and why
Mar 25 05:01:35 <MattB0ne> and just use the ethernet cord
Mar 25 05:01:44 <MattB0ne> well it appeared to work
Mar 25 05:01:53 <MattB0ne> but may have done more harm than good in the long run
Mar 25 05:01:59 <MattB0ne> thanks for your help though
Mar 25 05:02:19 <MattB0ne> your encyclopedic knowledge is dragging me along the learning curve
Mar 25 05:02:44 <MattB0ne> https://paulbupejr.com/beaglebone-black-internet-over-usb/
Mar 25 05:02:51 <MattB0ne> was where I got the instructions from
Mar 25 05:03:38 <MattB0ne> yeah i did do that one
Mar 25 10:57:09 <GenTooMan> afternoon zmatt
Mar 25 13:47:38 <MattB0ne> anyone have experience with 4D Systems LCD capes
Mar 25 13:48:28 <MattB0ne> or new haven displays
Mar 25 13:48:53 <MattB0ne> in the market for a capacitive touch screen
Mar 25 16:45:29 <kremlin> m
Mar 25 18:59:26 <uniqdom> Hello, I have an app that is printing to a log, let's say 100 bytes per second. I'm afraid of the eMMC endurance.
Mar 25 18:59:33 <uniqdom> should I?
Mar 25 19:00:07 <uniqdom> I have 2.6G available
Mar 25 19:00:18 <uniqdom> 2.6GB
Mar 25 19:02:38 <uniqdom> I have disabled the print to the log. It is printing to stdout now. But the app is executed as service by systemd. Systemd keeps a log of stdout in a file, right?
Mar 25 19:03:02 <uniqdom> journalctl -u project.service
Mar 25 19:03:17 <uniqdom> thats read from ram or from a file?
Mar 25 19:38:36 <uniqdom> nvm... those logs are in ram, as they are stored in /run/systemd/journal or /run/log/journal. And /run is a tmpfs.
Mar 25 19:56:13 <Jay81> Hello , anybody tried can-bus cap with BeagleBone AI ?
Mar 25 20:22:27 <yates_home> zmatt: on p. 11-8 of the ARM Cortex-A Series Programmer's Guide (section 11.1.3) they state in the text next to the "LDR PC, [PC, #offset] instruction that "This lets the exception handler be placed at any arbitrary address within the full 32-bit memory space". How can that be right? the offset is at most 24 bits!
Mar 25 22:02:00 <zmatt> yates_home: because it loads an address from a PC-relative location (e.g. a table right after the exception vector table) into PC, i.e. it's a doubly indirect branch
Mar 25 22:03:27 <zmatt> in an assembler you'd probably write    ldr pc, =my_exception_handler
Mar 25 22:07:00 <zmatt> though I'm pretty sure you can also just write bx my_exception_handler and let the linker deal with it :P
Mar 25 22:08:21 <zmatt> I prefer my approach anyway, which is jumping to nearby code that sets up a stack frame on the supervisor mode stack and then calls an exception handler with EABI-compatible calling convention (allowing the handler to be written in C/C++): https://liktaanjeneus.nl/start.S.html
Mar 25 22:08:56 <zmatt> avoiding the headache of all these cpu modes, each with their own stack :P
Mar 25 22:15:53 <zmatt> hmm, I wonder if I shouldn't have an "isb" before "cpsie a" in _start ... that just occurred to me.  although it probably doesn't matter on the cortex-a8
Mar 25 23:42:31 <DHeart> hey! Good evening
Mar 25 23:44:55 <DHeart> I'm trying to update a BBB that I have with Angstrom
Mar 25 23:45:16 <DHeart> and I followed the procedure in elinux.org
Mar 25 23:45:24 <zmatt> oh wow that's like prehistoric enough for a museum
Mar 25 23:45:27 <zmatt> what procedure?
Mar 25 23:45:39 <DHeart> flashing emmc
Mar 25 23:45:49 <DHeart> to update it to Debian
Mar 25 23:46:29 <zmatt> how old is your bbb?  is it a rev C or something older?
Mar 25 23:46:53 <DHeart> and on the /boot/uEnv.txt
Mar 25 23:47:09 <DHeart> yes. A rev C
Mar 25 23:47:31 <zmatt> ok
Mar 25 23:47:42 <DHeart> and I "un comment" the line
Mar 25 23:47:44 <DHeart> ##enable BBB: eMMC Flasher:#cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-flasher-v3.sh
Mar 25 23:48:05 <zmatt> so yeah, just flash the latest image (Debian 9.9 2019-08-03 4GB SD IoT) to sd card, boot from it, uncomment that line in its /boot/uEnv.txt, reboot and it should reflash your eMMC
Mar 25 23:48:19 <DHeart> I did
Mar 25 23:48:50 <DHeart> but, when I remove the sd card, it stucks on boot waiting for the card
Mar 25 23:49:31 <zmatt> then something clearly went wrong.  did you confirm it booted from SD card the first time (and not from eMMC) when you modified /boot/uEnv.txt ?
Mar 25 23:49:33 <DHeart> if I leave the card, it restarts the flashing process
Mar 25 23:49:53 <DHeart> yes, from the SDcard
Mar 25 23:50:32 <DHeart> I have it connected to a monitor and the las message is:
Mar 25 23:50:36 <zmatt> well once it starts the flashing process you'll obviously need to wait until it has completed or you'll have a non-bootable system
Mar 25 23:50:47 <zmatt> (it should turn itself off when it's done)
Mar 25 23:50:56 <DHeart> I waited for 1,5h
Mar 25 23:51:05 <zmatt> it should take like 10 minutes
Mar 25 23:51:47 <zmatt> I can't imagine any situation were it can be doing anything for 1.5 hours
Mar 25 23:52:07 <DHeart> yes but instead of finishing the flash process, turning off the the leds at the end, for me to reboot without the SD cad
Mar 25 23:52:24 <zmatt> ?
Mar 25 23:52:39 <DHeart> it blinks the four leds like a heart beat
Mar 25 23:52:50 <zmatt> that's an error, not completion
Mar 25 23:53:34 <DHeart> and the message is "writing to  [/dev/mmcblk1] failed"
Mar 25 23:53:47 <DHeart> stopping Cylon leds
Mar 25 23:53:56 <zmatt> which means you knew it was an error
Mar 25 23:54:02 <DHeart> setting leds to...........
Mar 25 23:54:16 <DHeart> yes but what error?
Mar 25 23:55:04 <DHeart> I know its an error because the expected behavior didn't happened
Mar 25 23:55:08 <zmatt> are you sure your BBB is rev C?   if it's *not* rev C it'll have a micron eMMC with part marking JW896: https://photos.app.goo.gl/rMKMX782wCyMJ9Wd6
Mar 25 23:56:07 <zmatt> (rev C has a Micron eMMC with part marking JWA06, or some Kingston eMMC)
Mar 25 23:58:47 <zmatt> and was there no error logged before "writing to  [/dev/mmcblk1] failed" ?
Mar 25 23:59:11 <DHeart> just checked and it has a JW896
Mar 26 00:00:05 <DHeart> no, no error before that one
Mar 26 00:00:38 <DHeart> bootloader writing sucessfull
Mar 26 00:00:52 <DHeart> partitioning also
Mar 26 00:01:08 <DHeart> creation of the rootfs also
Mar 26 00:01:10 <zmatt> then it's an old BBB with only 2GB of eMMC.  the current IoT image won't fit.  your options are to either flash the (fairly minimalistic) "console" image and then just install whatever packages you care about, or just wipe eMMC and use the IoT image (or whichever image you prefer) on sd card
Mar 26 00:01:34 <zmatt> the IoT image is too bloated
Mar 26 00:02:44 <DHeart> oh! ok! :)
Mar 26 00:02:54 <zmatt> console images for some reason aren't available on https://beagleboard.org/latest-images but you can find console images for debian stretch and debian buster on https://elinux.org/Beagleboard:BeagleBoneBlack_Debian
Mar 26 00:03:36 <DHeart> I assumed that all revisions of BBB were included in the latest images
Mar 26 00:04:12 <zmatt> they work on all BBB revisions, they just can't be flashed to eMMC on old ones
Mar 26 00:04:27 <zmatt> not enough space
Mar 26 00:04:46 <DHeart> it can only run on the SD card, right?
Mar 26 00:05:23 <DHeart> When I bought the BBB, it was sold as being a rev.C
Mar 26 00:05:48 <DHeart> if my memory serves me right
Mar 26 00:06:03 <zmatt> if you want to use the iot or lxqt image on a older-than-rev-C beaglebone you'll need to run from sd card (or try to strip the iot image down to fit in 2GB before flashing it, but that sounds painful).   the console image can be flashed comfortably
Mar 26 00:06:08 <zmatt> well it's not rev C
Mar 26 00:06:22 <zmatt> so if it was sold as rev C you should contact the distributor to complain
Mar 26 00:07:11 <DHeart> I can't remember when I bought and from whom I bought from
Mar 26 00:07:57 <DHeart> I had it stored for a while now.
Mar 26 00:08:21 <zmatt> if it came with angstrom it must have been old indeed
Mar 26 00:08:33 <DHeart> recently I thought in giving him a new purpose
Mar 26 00:09:04 <DHeart> to connect my 3D printer to the network
Mar 26 00:09:22 <DHeart> using octopi
Mar 26 00:09:53 <DHeart> thank you very much for your help
Mar 26 00:09:57 <zmatt> I suggest just flashing the console image, especially if you had previous experience with debian
Mar 26 00:10:12 <DHeart> I will try it now
Mar 26 00:10:59 <zmatt> note that the page I linked also has eMMC flasher images so you don't have to modify /boot/uEnv.txt yourself (that's the only difference between the microSD images and the eMMC flasher images)
Mar 26 00:14:39 <DHeart> ok
Mar 26 00:15:11 <DHeart> I've downloaded the Debian Stretch Console Snapshot
Mar 26 00:15:19 <DHeart> flasher version
Mar 26 00:15:42 <zmatt> I do wonder why buster isn't the default yet
Mar 26 00:17:16 <DHeart> testing?!? waiting to have some bug reports?!?
Mar 26 00:17:36 <zmatt> *shrug*   we've been using buster for quite a while now, but our systems don't really resemble the default images anymore
Mar 26 00:18:02 <zmatt> there's probably a good reason, I just wonder what that is
Mar 26 00:19:12 <DHeart> no idea. Has you might have noticed from my questions, I'm a newbie
Mar 26 00:19:32 <zmatt> :D
Mar 26 00:21:49 <DHeart> yes, it passed the point at which it gave the error
Mar 26 00:22:04 <DHeart> it's updating
Mar 26 00:22:11 <DHeart> thank you very much
Mar 26 00:32:49 <GenTooMan> The default images are interesting... (is that the correct wording?)
Mar 26 00:39:24 <zmatt> you mean obese? ;)
Mar 26 00:44:30 <MattB0ne> Dheart: we all start somewhere
Mar 26 00:44:42 <MattB0ne> it is nice having another boobies in the channel
Mar 26 00:45:03 <MattB0ne> I was holding it down for a while I am on my 4th EMMC flash
Mar 26 00:45:17 <MattB0ne> noobie*
Mar 26 00:45:44 <MattB0ne> I got my internet working and I am on to getting qt up and running
Mar 26 00:47:23 <set_> QT!
Mar 26 00:48:28 <set_> MattB0ne: How far along are you w/ getting QT up and running?
Mar 26 00:49:19 <set_> https://groups.google.com/d/msg/beagleboard/bGuAcHm0atc/JmFRxUa8AQAJ is something I found a while back from the google groups.
Mar 26 00:49:34 <MattB0ne> set_: not very just installed latest qt on my home comp now I am putting packages on the beagle
Mar 26 00:49:43 <set_> Aw. Okay.
Mar 26 00:49:44 <MattB0ne> thanks for the link I will take a look
Mar 26 00:49:47 <set_> Okay.
Mar 26 00:50:07 <set_> First and foremost, enjoy time on this planet and then BBB!
Mar 26 00:51:05 <MattB0ne> I know I know, this virus is perfect impetus to git gud at the BBB
Mar 26 00:51:25 <MattB0ne> I think we are going to stay in place official ly this friday
Mar 26 00:51:50 <set_> Right. I understand. I am usually stuck at this field all day. But...when not at the field, I try to find new ways to make the BBB do majestic things.
Mar 26 00:51:59 <set_> Pandemic!
Mar 26 00:52:04 <set_> Yikes.
Mar 26 00:53:12 <set_> Oh...NOTICE: to the bbb.io peoples. There is a bill to be passed soon that will grant allowances on loans if you do not fire workers and you retain them.
Mar 26 00:54:05 <set_> So, if you hire and not fire, you may be eligible. FYI. "A brother has to keep an eye out."
Mar 26 00:56:30 <MattB0ne> what are you using you BBB for
Mar 26 00:56:49 <MattB0ne> I am always curious about what people are doing with these things
Mar 26 01:00:05 <set_> Oh.
Mar 26 01:00:17 <set_> I do a bit of all stuff.
Mar 26 01:00:28 <set_> Bots w/ motors. I like my bots.
Mar 26 01:00:48 <set_> Computer aided vision w/ mjpg-streamer.
Mar 26 01:01:46 <set_> I have tried some sensors too, e.g. LDRs, LEDs, sonar, GPS, and other stuff.
Mar 26 01:02:19 <set_> I never know what to do next. Like they say, "The future is on the horizon."
Mar 26 01:04:04 <set_> MattB0ne: I am about to, was about to try (before ds2 ruined my logic), use a endoscope camera w/ an auger to check some pipe.
Mar 26 01:04:36 <set_> I was going to set up a base station of a BBB for promoting sewer inspection.
Mar 26 01:04:59 <set_> There is nothing dirtier than a dog w/ old bones.
Mar 26 01:05:23 <set_> And the BBBW...
Mar 26 01:05:34 <set_> Well, it has a good setup of WiFi on it.
Mar 26 01:06:04 <set_> You can run it on boot w/ video in real time and on WiFi so no Ethernet cable is required. This is a bonus.
Mar 26 01:06:24 <set_> I can move around w/out getting tripped up by cabling.
Mar 26 01:08:04 <MattB0ne> cool
Mar 26 01:08:39 <set_> Yep. Dirty but needed.
Mar 26 01:09:34 <set_> Man, I found one the other day on amazon. It was $800.00 large for a nice unit. I can move the BBBW w/ add on Cape for a LCD Screen for cheaper than that idea.
Mar 26 01:10:09 <MattB0ne> have you bought an LCD cape before I am in the market for one
Mar 26 01:10:09 <set_> MattB0ne: Are you good w/ Qt already?
Mar 26 01:10:14 <set_> Yes.
Mar 26 01:10:32 <MattB0ne> but I still want to use some of the pins
Mar 26 01:10:38 <set_> Oh.
Mar 26 01:10:40 <set_> Hmm.
Mar 26 01:10:51 <MattB0ne> I noticed a lot of them take over the entire board
Mar 26 01:11:01 <set_> I think there is a way but you might have to rig it or "hack" it.
Mar 26 01:11:09 <set_> Clip pins and such...
Mar 26 01:11:27 <set_> Most of the Capes I have found all take over the entire board.
Mar 26 01:11:32 <MattB0ne> I have a BB green so I would still have the Grove ports
Mar 26 01:12:08 <MattB0ne> if I can have one that could go from Grove to some sort of interface for serial communication but would be good
Mar 26 01:12:21 <MattB0ne> that or find a cape that leaves some pins available
Mar 26 01:13:09 <set_> Oh. Yea. I was thinking about it. Let me see if I can find a Cape for that real quickly. I know most if not all take up both header pins on each P8 and P9.
Mar 26 01:14:08 <MattB0ne> yeah which sucks
Mar 26 01:15:35 <set_> https://4dsystems.com.au/products/4d-intelligent-hmi-display-modules has some ideas. I could get really lost easily in a LCD search.
Mar 26 01:16:17 <set_> I found these Capes a while back. There are some strickly for the BBB and other family boards w/ the P8 and P9 headers.
Mar 26 01:16:41 <set_> But...like you said. They take up the header pins.
Mar 26 01:18:07 <set_> https://4dsystems.com.au/catalogsearch/result/?q=+BeagleBone+Black+4DCape
Mar 26 01:21:07 <set_> You could attach a Micro HDMI cable to a LCD monitor?
Mar 26 01:21:13 <set_> I mean...right?
Mar 26 01:21:25 <set_> I mean...dang it.
Mar 26 01:22:02 <set_> From the BBB (micro hdmi) to a monitor or other peripheral (hdmi).
Mar 26 01:23:20 <set_> Well, this may be better for me. I do want to make a stand alone station for minor viewing in real time and for ease of access.
Mar 26 01:23:54 <MattB0ne> the green doesn't have a HDMI port they cut it to save money
Mar 26 01:23:59 <set_> Oh.
Mar 26 01:24:07 <set_> Okay, really?
Mar 26 01:24:09 <set_> Let me see.
Mar 26 01:24:12 <set_> brb
Mar 26 01:24:55 <set_> Dang. No joke. You are right.
Mar 26 01:25:17 <set_> No micro hdmi. Hmm. Do you have a BBB at all? I know the BBB has it on it.
Mar 26 01:27:17 <set_> Anyway, stand alone w/ hdmi or a Cape, LCD exists!
Mar 26 01:27:34 <set_> You can probably wire one.
Mar 26 01:28:13 <set_> If the Cape is open source and it states which pins go to what pins on the BBG, you might be able to wire it away from the BBB.
Mar 26 01:28:25 <set_> BBB = BBG, sorry.
Mar 26 01:30:57 <set_> Then, you can use those pins. For instance, all the LCD pins on the BBG will most likely be used (guessing). Then, you can get female to female wiring. Make the connections w/ those wires and then use your leftover pins for whatever.
Mar 26 01:31:34 <set_> But...I am totally guessing. I can help you help me help you. If that makes sense.
Mar 26 01:32:37 <set_> I like learning more too. If you get bored and want to reach out on the Cape you purchase, Seeed Studio has some dedicated to the BBG but the LCD screens they have might not be ready for future kernel use.
Mar 26 01:33:28 <set_> I typed that b/c someone told me that w/ my current cape, I should not update my kernel right now b/c the repo has no tech. for the onboard chip.
Mar 26 01:40:27 <set_> So, you may want to check w/ the chip onboard to see if the kernel will provide support or if you are ready to type up some kernel driver for that chip and the BBG.
Mar 26 01:49:33 <MattB0ne> I saw they have an HDMI cape
Mar 26 01:50:07 <MattB0ne> I can get that
Mar 26 01:50:58 <set_> No.
Mar 26 01:50:59 <MattB0ne> I was looking at this one LCD manufacturer
Mar 26 01:51:08 <MattB0ne> ???
Mar 26 01:51:23 <set_> MattB0ne: I think the HDMI Cape went extinct. No more support.
Mar 26 01:51:41 <set_> You may want to wait around for another person to answer that correctly but that is what I heard.
Mar 26 01:52:02 <set_> Which mfg?
Mar 26 01:55:48 <set_> MattB0ne: Hey...I see Seeed Studio is representing an updated firmware version but I say check the chip in the newer kernels on github.
Mar 26 01:56:11 <set_> Who knows? It may be supported and I could be wrong but...
Mar 26 01:56:38 <set_> I think the Cape is de funct for now. I do not own it. So, this is garbage talk really.
Mar 26 01:57:08 <set_> Does anyone have the HDMI Cape from Seeed Studio?
Mar 26 01:58:30 <set_> MattB0ne: I will go to the new forum for Seeed Studio and ask.
Mar 26 02:02:05 <GenTooMan> MattB0ne an LCD cape would work for you just plug it in. The frame buffer driver will likely move the data you want to where you want. This reminds me I need to actually finish an LCD cape for the Display Tech DT070CTFT. Heh one of many projects I forget to work on.
Mar 26 02:02:42 <set_> GenTooMan: You are the busiest person in show bizness.
Mar 26 02:03:46 <set_> MattB0ne: Here... >>> https://forum.seeedstudio.com/t/re-the-hdmi-cape-for-the-bbg/251093 <<< is that good enough?
Mar 26 02:10:30 <set_> I will wait for a bit. Hopefully, someone will answer.
Mar 26 02:12:35 <GenTooMan> The old HDMI board for the BBB isn't around anymore and you can check the date on the schematics seeed studio keeps stuff around for a bit. It appears they are still selling the HDMI cape for the green.
Mar 26 02:20:48 <set_> https://www.seeedstudio.com/Seeed-Studio-BeagleBoner-Green-HDMI-Cape.html
Mar 26 02:27:00 <set_> it has the wheezy or jessie Debian OS as a firmware for the board. If you purchase it, please let me know if it works.
Mar 26 02:41:25 <GenTooMan> I suggest looking at the schematic
Mar 26 02:42:42 <set_> Okay. So, I am off to read their schematic. If I come up w/ one, I will post again in here.
Mar 26 02:44:32 <set_> I found it on digikey.
Mar 26 02:44:48 <set_> They have a few pages of info. dedicated to the HDMI Cape.
Mar 26 02:46:52 <GenTooMan> if the schematic points match that of the BBB for the LCD lines it should just work.
Mar 26 02:47:09 <set_> http://www.ite.com.tw/en/product/view?mid=20 <<< I think this is the chip onboard.
Mar 26 02:47:12 <set_> Oh.
Mar 26 02:51:15 <set_> I do not know what to say next. I read over the info. presented as a schematic. It is odd but not a schematic.
Mar 26 02:51:20 <set_> I must have missed something.
Mar 26 02:51:55 <GenTooMan> this ? https://raw.githubusercontent.com/SeeedDocument/BeagleBone_Green_HDMI_Cape/master/res/Schematic_Files.zip
Mar 26 02:52:01 <set_> Aw.
Mar 26 02:52:27 <set_> Nope. I was reading a digikey setup guide.
Mar 26 02:52:34 <set_> Oh well.
Mar 26 02:53:04 <set_> Did MatB0ne get bored w/ this idea?
Mar 26 02:53:53 <set_> Sorry. MattB0ne and not MatB0ne. Sorry again.
Mar 26 02:59:32 <GenTooMan> Well anyhow it appears that all the bits are their, it's a different controller however. So setting it up may be problematic.
Mar 26 03:01:52 <GenTooMan> It was released in 2017 so whatever was being used at the time is the driver.
