Has anyone here got ELBE to work on Linux Debian so far to the point that it installs w/ the correct dependencies? I think I can pick and place later. For now, I am really trying to just get past "a 20% finishing installation" 'bug' or issue.

I want to do TFTP Boot with Beaglebone Black via USB0 device on Windows 10.
<Guest0>
However, in Windows 10, the usb0 network adapter is not captured. => u-boot
<Guest0>
When I log in Beaglebon Black, the usb0 network adapter is caught.
<Guest0>
Is it normal that the usb0 network adapter is not caught on the u-boot?
<Guest0>
I wonder if I need to make additional settings.
<zmatt>
what you mean by "the usb0 network adapter is not captured" ?
<zmatt>
tftp boot is tricky to get working, and I have no idea how it would be done on windows
<Guest0>
I try to boot TFTP using USB0 device,
<Guest0>
but when I enter the u-boot, I can't catch the USB0 device on Windows 10.
<Guest0>
No network adapter found in Windows 10.
<zmatt>
not sure, might be an issue with how u-boot is configured (e.g. if it shows up as a usb-standard-compliant networking device rather than using Microsoft's proprietary RNDIS protocol) or some issue with Windows, I have no idea

Hi GoodMorning
<tigerxyz>
I turned off/on with ifconfig for SoftAp0 interface. But now, SoftAp0 is down (not listed) even it is rebooted. Anyway to reset and bring it up
<tigerxyz>
Ok, I found that I changed TETHER_ENABLED=no . With yes, SoftAp0 is up.

If I lost my ssh private key but I have the bb green here. Is there a way to obtain access to it? Can I somehow offline-mount the image on it and install a new ssh key?
<otisolsen70>
I do not want to re-image it if I can avoid it as I would like to have some unsaved stuff on it.
<zmatt>
that's an option. you can't login simply with username/password ?
<zmatt>
if you've disabled password authentication for ssh then you can still login using password on the serial console (as well as the usb-serial one if enabled). you can also boot the beaglebone from a bootable sd card (make sure it's not a flasher), mount the eMMC, and fix things

zmatt, I disabled passwordauth. How do I mount the on-board image off line on a different machine? Do I just connect it via USB? (sorry, I am new to this)
<samael>
otisolsen70: just flash a console image (be careful to avoid flasher images as already mentioned) into a uSD card and boot from it. then login via ssh/usb/serial console and mount the onboard eMMC to access your data
<otisolsen70>
samael, do you have a link to an image I can use without damaging/overwriting any of the stuff that is already on the device?
<samael>
i'm not up to date with recent images, and i don't think i ever used any bb green, but following the link in the topic http://bbb.io/latest i believe you can safely pick one from the Debian console images section
<Guest45>
what are difference between beaglebone black rev c and rev a5
<Guest45>
and which one is best
Guest66 has joined #beagle
Guest45 has quit [Client Quit]
Guest66 has quit [Client Quit]
<zmatt>
rev c is current revision
<zmatt>
the biggest difference is that rev c has larger eMMC size
<zmatt>
otisolsen70: once booted from an sd card, log into it (with the default username/password), mount the eMMC (sudo mount /dev/mmcblk1p1 /mnt), edit the relevant settings on it (e.g. /mnt/home/debian/.ssh/authorized_keys), unmount it (sudo umount /mnt), shut down (sudo poweroff) and remove the sd card

hi all, I have a question,
<Guest72>
Does anyone knows is it possible to use Jupiter notebook instead of cloud 9 for BBB?
<Guest72>
if yes, how can I import adafruit library
<Guest72>
thanks
Guest27 has joined #beagle
<otisolsen70>
samael, so I can dd this image (https://debian.beagleboard.org/images/bone-debian-10.3-console-armhf-2020-04-06-1gb.img.xz) do a microSD, plug it in the bb green. Power BBG on and boot it up on this image. Then mount the on board image (located in /dev/???) and then install my key. Power off BBG. Plug out my microSD. Power on BBG. Then SSH in. Correct?
<otisolsen70>
zmatt, thjanks

I'm trying to install bison on my BBB running Debian 10.3, but it keeps failing saying "Cannot initiate the connection to debian.map.fastlydns.net...Network is unreachable". Is this a problem on my end or is something up with Debian's repos for arm?
<Guest27>
I did run apt-get update first, BTW.
<Guest27>
This happens when it tries to pull down libbison-dev.
<zmatt>
there doesn't seem anything wrong with debian's repos, but that hostname seems odd to me
<zmatt>
that's not the hostname of a debian repo
<Guest27>
Some sort of DNS contamination at my provider?
<Guest27>
A subsequent message says it can't connect to deb.debian.org; is that a legit debian repo URL?
<zmatt>
fair, that's true, so just because it's fine for me doesn't mean it can't have problem for you
<zmatt>
does it work normally in your web browser?
<zmatt>
ohh maybe there *is* an issue with it... it says one of its SRV records is pointing to prod.debian.map.fastly.net but that instance indeed seems down
<Guest27>
I don't understand. Do you mean point my web browser at deb.debian.org?
<zmatt>
yeah
<zmatt>
I'm wondering if there's a way to see what instance apt is connecting to here
<Guest27>
BBB is CL only, no GUI. Could try with a CL-based browser, I suppose.
LetoThe2nd has quit [Quit: Connection closed for inactivity]
<zmatt>
I mean on your computer
<zmatt>
any device that shares the same internet connection as the beaglebone
<Guest27>
Ah, ok. Let me check...
<zmatt>
okay this is weird, ths SRV record resolves to debian.map.fastlydns.net for me, which indeed fails... yet I just did an apt upgrade with no problems
<Guest27>
Yes, that seems to work fine. I get a page that says 'welcome to deb.debian.org (fastly instance)!"
<Guest27>
Looks like a fastly problem. If I point my browser at debian.map.fastlydns.net it returns "Fastly error: unknown domain: debian.map.fastlydns.net. Please check that this domain has been added to a service. Details: cache-mdw17333-MDW
<zmatt>
you could try configuring a different mirror in /etc/apt/sources.list
<zmatt>
e.g. explicitly cdn-fastly.deb.debian.org or alternatively cdn-aws.deb.debian.org
<zmatt>
see if that helps
<Guest27>
Do I need to change all the lines, e.g., the buster line (yes, obviously), but also buster-updates and debian-security buster/updates?
<zmatt>
generally you want all of them to point to the same repo yes
samael is now known as shamshel
shamshel is now known as samael
<Guest27>
I switched tocdn-aws.deb.debian.org. When I run apt-get update , the buster and buster-updates seem to go fine, but I'm getting "Cannot initiate connection to cdn-aws.deb.debian.org" errors on debian-security.
<zmatt>
if it cannot initiate connection then it hasn't reached the point of being able to send a http request, i.e. there's no difference between the different requests yet... suggesting you're just having random failures?
<samael>
Guest27: make a pastebin of your sources.list pls
<Guest27>
Found the problem: default gateway on the BBB.
<zmatt>
you've been messing with network settings?
<Guest27>
I added a second ethernet adapter to the BBB (USB) to be able to apt-get install some stuff such as bison. But the default GW was still pointing at the other interface which goes to a device that the BBB is/will monitor, i.e., a dead end.
<Guest27>
I change the default GW and then apt-get worked fine, was able to install bison, etc.
<Guest27>
PEBKAC
<zmatt>
oh you're using internet access via usb rather than via ethernet?
<Guest27>
zmatt, yess
<zmatt>
that often causes problems since you'll be fighting connman (which deems itself in full control over default gateway)
<Guest27>
Yeah, so I've discovered.
<zmatt>
connman is just rude, I don't know why the bb.org images use it
<Guest27>
The USB adapter is temporary, so not a big deal, I guess.
<zmatt>
not sure what you mean by that
<zmatt>
the usb adapters (usb0 and usb1) are setup by a boot script
<Guest27>
I wondered about the choice of connman, too. It's described as a network manager for use in embedded systems, but really, how hard is it to just modify /etc/network/iinterfaces?
<zmatt>
(which is also gross)
<zmatt>
ifupdown is pretty terrible, I don't know why that's installed either, especially since anything you do in there will almost certainly conflict with connman
<Guest27>
No, this is a physically separate USB adapter.
<zmatt>
uhh huh what
<zmatt>
how/why ?
<zmatt>
what do you mean by physically separate USB adapter ?
<Guest27>
Not using the usb0 or usb1 adapters.
<zmatt>
that doesn't really answer the question... you mean like an usb-ethernet adapter plugged into the usb host port? if so, why not use built-in ethernet?
<Guest27>
I'm connected to the BBB via serial. I needed to add a second physical ethernet adapater so I plugged one into the USB port on the BBB.
<Guest27>
Built-in ethernet is hard-wired to a device for monitoring purposes, isolated subnet.

i.e., no outside network connectivity.
<zmatt>
okay that's kinda weird, though connman should probably have handled that just fine I think?
<zmatt>
dunno, I'm not super familiar with connman
<zmatt>
I replace it with systemd-networkd on our beaglebones
<Guest27>
I thought so too, but the default GW got messed up as mentioned. But the second adapter is just temporary, to pull down some libraries.
<zmatt>
well you tried configuring it via /etc/network/interfaces, not via connman
<zmatt>
anything you do in /etc/network/interfaces is behind connman's back, and connman will fight you
<Guest27>
No, I used connman, set it for dhcp. I just don't see what connman offers over the interfaces file, but I'm sure the Debian devs had good reasons.
<zmatt>
oh then I misunderstood
<zmatt>
well debian devs didn't choose it
<Guest27>
I'm just used to interfaces from years of use.
<Guest27>
Oh, was connman a BB choice?
<zmatt>
yeah that's the config file for debian's custom ifupdown system
<zmatt>
yes
<zmatt>
I haven't used ifupdown in ages, iirc it tended to slow down boot (especially if not connected to network on boot). I've been a happy systemd-networkd user for many years now
<samael>
for quick temporary internet connections i find very handy to link the bbb to my laptop via the usb cable, replace the default route on the bbb and turn on masquerading on the laptop to act as a gateway for the bbb. don't know if connman takes precedence in later images; in older ones usb virtual adapters where not under connman control
<zmatt>
I'm not sure which adapters connman will control, but it will control the default gateway regardless
<zmatt>
it normally also controls the /etc/resolv.conf file
<samael>
zmatt: what you say seems fun to me. i use both ifupdown and sd-nd, and i need to explicitly impose a timeout everywhere right because of uncontrollable delays at boot (never experienced with ifupdown)
<zmatt>
messing with either of those behind its back has essentially undefined results
akaWolf has quit [Ping timeout: 258 seconds]
<zmatt>
systemd-networkd doesn't impose any boot delays unless you have services that depend on the deprecated systemd-networkd-wait-online.service
<zmatt>
(and you can configure which links matter for that service)
<samael>
i usually set the gateway with very low metric. anyway i think you're right, i get really angry when something mess up dns and others. that's why i turn down network managers
<zmatt>
systemd-networkd is very non-invasive in my experience, it doesn't mess with your stuff
<zmatt>
connman otoh is very controlling and rude
<zmatt>
I don't know how ifupdown behaves in that regard, I haven't used it in recent times
<zmatt>
I think ifupdown launches dhclient? which itself is more invasive than systemd-networkd I think, but I'm not sure
<samael>
yes, interfaces spawn dhclient since ancient times. i'm very used to both, they are far less invasive than any network manager i tried until now
<zmatt>
obviously being used to something makes a big difference too

arg freenode is ruined
<mattb0ne>
you need to set a pw just to log on to the lobby?
<zmatt>
easy fix: don't bother connecting to freenode anymore
<zmatt>
there's nothing of value left there
<zmatt>
like >80% of the channels left were just implicitly created by automatically reconnecting clients
<mattb0ne>
ok the channel did not disappear it went +r
<zmatt>
what channel?
<mattb0ne>
opencv
<zmatt>
is there no opencv channel on libera?
<mattb0ne>
there was then they changed the settings so you need to have a registered name
<mattb0ne>
i was not looking at the error log
<mattb0ne>
* #opencv :Cannot join channel (+r) - you need to be logged into your NickServ account
<zmatt>
why not register your nick?
<mattb0ne>
on freenode i made my PW too long and I hated typing it
<mattb0ne>
so that is why I would show up as mattb0000000ne
<mattb0ne>
lol
<zmatt>
why not use a decent irc client and configure it to save your password for you? :P
<mattb0ne>
i have hexchat I havent bothered looking for a client but I was going to ask about that
<zmatt>
same as in C, C++, c#, java, javascript, perl, shell scripts, and no doubt numerous other languages
<zmatt>
you can find more guides on how to configure various clients to automatically authenticate you to nickserv here: https://libera.chat/guides/sasl
