Bertl : I've tried this one sooner this month. Is it slightly different ?
10:20
Bertl
it is an update with additional drivers
10:20
max_bxl
my bad, I didn't the "modules" at the beginning of it !
10:20
max_bxl
trying
10:25
Bertl
you might need a 'depmod -va' to get the cache updated
10:25
max_bxl
ok I've uncompressed the archive in /opt/
10:25
max_bxl
now "depmod -va" ?
10:26
Bertl
what were the exact commands you did? (patebin)

okay, looks good, yes, run the depmod -va to make sure they are updated
10:31
Bertl
and plug in the wifi dongle to test
10:31
Bertl
check what 'dmesg' reports and if it doesn't work, upload the output of 'dmesg' and 'lsusb -v' somewhere
10:33

10:34
max_bxl
the dongle doesn't work
10:37
Bertl
what does 'modinfo ath9k_htc' say?
10:37
Bertl
(pastebin for everything longer than 3 lines)
10:37
max_bxl
[root@beta /]# modinfo ath9k_htc
10:37
max_bxl
modinfo: ERROR: Module ath9k_htc not found.
10:37
Bertl
what does 'uname -a' report?
10:38
max_bxl
Linux beta 4.6.0-xilinx-00016-gb49271f #53 SMP PREEMPT Mon Jan 9 01:07:28 CET 2017 armv7l GNU/Linux
10:38
max_bxl
hum...
10:38
Bertl
you are running the old kernel :)
10:38
max_bxl
ok !
10:39
Bertl
please do the update we had last week, then repeat the update from today
10:39
max_bxl
let me bring the new kernel to life
10:45
max_bxl
kernel updated
10:48
max_bxl
modules uncompressed and "depmod -va" done but the dongle still doesn't work
10:49
Bertl
did you reboot?
10:49
max_bxl
not after depmod ... rebooting
10:50
Bertl
also check with 'uname -a' that the new kernel is active
10:50
Bertl
then repeat the 'modinfo ath9k_htc'
10:51
max_bxl
green light on the dongle !
10:51
max_bxl
youpi !
10:52
max_bxl
if needed : modinfo => https://quotidien.framapad.org/p/herbert-axiom-wifi-pastebin
10:54
max_bxl
thank you Bertl !
10:57
Bertl
excellent!
11:01
max_bxl
ok, now I tried to set up an access point with what is written in the wiki ( iwconfig wlan0 essid "yourhotspotname" enc "WEPpassword" )
11:01
max_bxl
no error message but I still don't see the Beta ESSID
11:02
Bertl
you probably want to use enc s:Password
11:02
Bertl
(unless you really specify the key and not a password :)
11:02
max_bxl
after googling, I found that I maybe need dhclient wlan0
11:02
max_bxl
yep: I specified a key
11:04
max_bxl
does it seem correct to run "dhclient wlan0" ? (then I need to install it ^^)
11:05
Bertl
shouldn't be required to get connected to an access point
11:09
max_bxl
iwconfig wlan0 essid "yourhotspotname" enc "WEPkey" should be enough ? Or should I also run hostapd ?
11:09
Bertl
enough for what?
11:10
Bertl
if you are connecting to a station using WEP and the WEPkey, then that should be enough
11:10
Bertl
you still need to bring up the interface and request an IP via dhcp in case the station provides dhcp
11:11
Bertl
alternatively you can set your own IP and use that
11:14
max_bxl
hum... sorry for the unprecise question : I'd like to make to access the Beta from a computer/smartphone over wifi, the Beta "providing" the network itself. I've done this with a Raspberry Pi and hostapd, hence the question.
11:14
Bertl
well, does the dongle support station mode?
11:14
Bertl
what does 'iwconfig wlan0 mode station' give?
11:15
max_bxl
Error for wireless request "Set Mode" (8B06) :
11:15
max_bxl
invalid argument "station".
11:16
Bertl
try 'master' instead of station
11:16
max_bxl
Error for wireless request "Set Mode" (8B06) :
11:16
max_bxl
SET failed on device wlan0 ; Invalid argument.
11:17
Bertl
so the dongle itself doesn't support station mode, it might work with hostapd, but I have never tried that, so you have to read some (Arch) docs
11:18
max_bxl
ok, will do (tonight maybe)
11:22
max_bxl
since I'm going to install stuff on the beta (hostapd, ...), could you remember me what would be the best solution to make more space on the beta ?
11:22
max_bxl
(like cleaning the pacman caches ?
11:22
max_bxl
)
11:23
Bertl
yes, cleaning up the pacman caches :)
11:23
Bertl
you can also get rid of the logs and journald entries if you like
11:27
max_bxl
"pacman -Sc" then ?
11:27
Bertl
https://wiki.archlinux.org/index.php/pacman
11:28
max_bxl
and delete the files in /var/log/journal ?
11:28
Bertl
https://wiki.archlinux.org/index.php/systemd
11:30
max_bxl
[root@beta ~]# pacman -Sc
11:30
max_bxl
error: failed to init transaction (unable to lock database)
11:30
max_bxl
error: could not lock database: File exists
11:30
max_bxl
if you're sure a package manager is not already
11:30
max_bxl
running, you can remove /var/lib/pacman/db.lck
11:31
Bertl
well, is pacman already running?
11:31
Bertl
if no, then remove the lock
11:32
max_bxl
done, and working
11:33
max_bxl
is the lock on by default because of archlinux or because you prepared it that way
11:33
max_bxl
?
11:34
Bertl
it was probably there because you turned off the Beta while pacman was running (without shuting it down properly)
11:38
max_bxl
ok
11:38
max_bxl
cleaning done (cache + logs) and I freed 500MB !
11:39
Bertl
\o/
11:39
max_bxl
leaving now
11:39
Bertl
have fun and cya!
11:39
max_bxl
I'm going to pimp the beta with rigs from a rental house
11:39
Bertl
happy pimping then!
11:39
max_bxl
maybe I'll have pictures for tonight IRC meeting !
11:40
max_bxl
cya n' thx !

Hello all
17:02
RexOrCine
Present.
17:04
intrac
hello
17:05
Bertl
so I got requests to report from anuditverma, Champika and niculescu_vlad|a (in alphabetical order)
17:05
Bertl
so please, anuditverma, begin
17:05
RexOrCine
I might not make it to the end of the meeting as it's past my bed, but I emailed Hermann. Nothing to report besides that.
17:06
anuditverma
ok, I have updated the readme file of my project repository
17:06
anuditverma
https://github.com/apertus-open-source-cinema/axiom-beta-rest-interface/tree/develop
17:07
anuditverma
If anyone wants to setup development environment and try the current implementation of the client app, though it's still in alpha stage, a lot needs to be done, with all the methods and REST implementation, I am targeting to cover most the work before the first evaluation i.e. by end of this month
17:08
anuditverma
That will be all from my side
17:08
Bertl
sounds good
17:08
Bertl
thanks for the update!
17:08
Bertl
Champika: the channel is yours!
17:08
Champika
Ok, so I had finished my 7th semester exams by last IRC meeting
17:09
Champika
But I was not able to present in last meeting, because I was at medical center due to flu
17:10
Champika
I study about the routing fabric of Beta setup and I have created a wiki page for that
17:10
Champika
https://wiki.apertus.org/index.php/Routing_Fabric
17:10
Champika
Also, I study about how the PIC code works, how the JTAG communications are done.
17:11
Champika
I also created a wiki page about the PIC code
17:11
Champika
https://wiki.apertus.org/index.php/PIC_code_explanation
17:11
Champika
Then, on last few days I was setting up a qemu to emulate the beta
17:11
Champika
still working on that process
17:12
Champika
Then hope to create a simple driver by end of this month.
17:12

17:12

17:13
Bertl
thanks a lot for the update!
17:13
Bertl
niculescu_vlad|a: the stage is yours!
17:13
niculescu_vlad|a
Ok
17:14
niculescu_vlad|a
So, in the last two weeks I finished the PCB and sent it to factory. They told me it was done on June 14 and now I'm waiting for it to come (hopefully this week)
17:15
niculescu_vlad|a
I also developed a UART module in Verilog. The DC DC switcher has to be controlled from PC for tests, so that is why UART was necessary
17:16
niculescu_vlad|a
the output voltage will be communicated to switcher via I2c. So the test procedure will be like: PC-UART-I2c master- I2c Slave
17:16
niculescu_vlad|a
I also did the first attempt of I2c master. Now I am restructuring it
17:17
niculescu_vlad|a
So by the end of this week I hope to have both I2C Slave and Master
17:18
niculescu_vlad|a
that is all. After I have those and the PCBs will come, I will assembly the parts and test the I2C with our DAC
17:18
niculescu_vlad|a
that is all
17:18
Bertl
excellent! thanks for the update!
17:18
Bertl
anybody else who wants to report something?
17:19
Bertl
from my side, a short update what we did and what we are working on right now:
17:19
Bertl
we finished our 'Maker Faire' tour last week with the Maker Faire Berlin
17:20
Bertl
(very sucessfully) and we again got honored with the 'Maker of Merit' badge
17:21
Bertl
now we are currently focusing on testing all the hardware we designed over the last few months (mostly plugins and extensions, but also some modifications)
17:21
Bertl
and of course, GSoC is a main focus now as well, as the first evaluation gets near
17:22
Bertl
that's basically it from my side as well, and if nobody else wants to report anything and there are no questions, then the only task left is to find a time and date for the next meeting
17:23
[A]
I'm not really part of this community
17:23
[A]
and I'm not sure if this 'fits' into reporting
17:23
[A]
but given that I managed to log in in time, given that you are inviting people to talk...
17:24
[A]
what's the hidden trick to subscribe to your mailing lists? :)
17:24
Bertl
well, I'm not aware of a trick there .. some are public, others are invite only
17:24
[A]
silly as it sounds, I found that quite unfriendly :P
17:25
Bertl
but best to check with RexOrCine or se6astian, because I'm not maintaining those lists
17:25
[A]
only the axiom-community list accepts subscriptions
17:25
[A]
despite other lists also marked as public
17:25
[A]
there's a note "it works just fine with any other email address as well just requires a little trick to add that address to the group"
17:26
[A]
but it's not documented ;)
17:26
RexOrCine[m]
Will you send me a mail on rex at apertus dot org please my friend.
17:27
[A]
sure
17:27
RexOrCine[m]
And I'll sort that when I wake up.
17:27
RexOrCine[m]
Thanks. And welcome by the way.
17:28
Bertl
so for the next meeting, I would suggest Monday, the 3rd of July, 19:00 CEST
17:28
niculescu_vlad|a
It's ok for me!
17:28
Champika
I'm fine with that time.
17:28
anuditverma
fine by me
17:29
Bertl
RexOrCine, davidak?
17:29
davidak
no
17:29
davidak
ah, yes
17:29
davidak
time is ok with me
17:30
RexOrCine[m]
Ah yeah I'm always good with whatever.
17:30
Bertl
perfect, so that's settled then and we conclude the meeting
17:30
Bertl
se6astian will write up the meeting minutes (from the logs) later
17:31
Bertl
feel free to exchange thoughts or discuss details here on the channel now
17:31

Is he still getting his makeover?

hmm, I'm not sure if "reflected" is the right word there, maybe "returned" would be preferable

is there anybody who has pulled focus by measurement tape?
20:54
Bertl
probably
20:54
toxitobi
I have to figure out how a mounting point for such a tape should look like
20:55
toxitobi
and which point needs to be on the same plane as the sensor
20:56
Bertl
I don't think that this is done in such a precise manner :)
20:57
Bertl
but maybe se6astian knows more
20:58
toxitobi
Jeah for the standard home measurement tape a grrove would be great
20:58
toxitobi
so you can just put it in this groove and measure but this part should be out of metal so the magnet works
20:59
toxitobi
but on the c100 I think it's just an eyelet
