MEETING TIME!
17:00
se6astian
who is here?
17:00
Bertl
is here ...
17:02
tpw_rules
hi i am here for once
17:02
Bertl
who are you? :)
17:03
se6astian
tpw_rules: any news from you to share?
17:03
vup
is here
17:03
tpw_rules
no, just wanted to say i still exist. but i have a thesis due in 2 weeks and have been insanely busy on that. i was waiting for news on the Beta with HDMI access. do i need to provide any information for that? is it ready?
17:04
vup
we should have a setup for that now
17:04
tpw_rules
ok, how do i get access?
17:05
vup
ill msg you how to connect, I assume using the same ssh key as always is fine?
17:05
tpw_rules
yes
17:05
vup
great
17:06
tpw_rules
there should be two on the beta, but i can add the other if you add one
17:06
vup
ok
17:07
se6astian
vup/anuejn any news from your side? I see lots of commit messages in the last few days
17:07
vup
sure a bit
17:08
vup
finally got to merge the subpass rendering into narui (https://github.com/apertus-open-source-cinema/narui/pull/15)
17:08
vup
and also did some more cleanup on some internals of narui (https://github.com/apertus-open-source-cinema/narui/pull/22) which makes it more fool proof to use and makes everything a bit cleaner
17:09
vup
finally I also did some various bug fixes for axiom-firmware
17:09
vup
so the CI now runs through on main again and we should get up to date releases again
17:10
vup
(you can find that here: https://github.com/apertus-open-source-cinema/axiom-firmware/pull/186)
17:10
vup
thats it from me
17:10
se6astian
great, many thanks
17:10
se6astian
should the new release now detect my powerboard version?
17:11
se6astian
and run through axiom-start?
17:11
se6astian
or does that still require investigation?
17:11
vup
unclear
17:11
vup
I did not have the time yet to look at the changes of the new powerboard version
17:12
se6astian
ok, let me know if I can supply/do anything in that regard
17:12
se6astian
BAndiT1983: any news from your side?
17:13
BAndiT1983
nope, not really, some research for remote and SAME70
17:14
se6astian
ok then quick updates from me
17:14
se6astian
and if nobody else wants to share anything closing words from bertl as usual :)
17:14
se6astian
I just soldered and tested a dual USB power adapter cable so I can also test the beta UHD/4K raw mode in the field soon
17:15
se6astian
further recording/conversion/finetuning in that regard is ongoing, maybe bertl wants to say something about the UHD -> 4K hdmi upgrade afterwards
17:16
se6astian
currently the focus is evaluation the darkframe calibration - something is not working as expected likely an issue because the frames we capture are not the expected 4096x3072 resolution or missing metadata with the raw2dng tool
17:17
se6astian
had a vc with curved image sensor manufacturer last week and there is potential ground for a joint grant and research project to get the curved image sensor and beta with it closer to market
17:17
se6astian
we will discuss details next week probably
17:18
se6astian
another grant to collaborate with the technical university vienna for getting the compact enclosure closer to production has also been drafted and is now in internal review
17:18
se6astian
its a rather brief application and rather small grant
17:19
se6astian
last screws/springs/nuts have now arrived today and after paying VAT around 3 times I can soon assemble the second Tele produced Dev kit
17:19
se6astian
thats all I can remember from my side currently
17:19
se6astian
anyone else ready to share now? otherwise Bertl please do!
17:20
Bertl
yeah, it seems our intern is missing out today ...
17:20
Bertl
let's hope that will get better soon ...
17:20
Bertl
I was mostly busy with improving the raw HDMI transfer and testing various modes
17:21
Bertl
for this purpose, I adapted the generator setup to calculate the register settings from a simple timing data array
17:22
Bertl
so you can basically use the typical modeline data to set sync, front porch, back porch and active display and the script takes care of the rest
17:22
Bertl
this was mainly done to test more atypical modes like 2048x1080 and of course the 2048x1536 which contains the entire sensor data
17:23
Bertl
again we did hit the USB bandwidth limit slightly below 400MByte/s which seems to be the practical limit for USB despite the theoretical limit of 500MByte/s
17:24
Bertl
so around 388-390MByte, the Magewell capture tool starts dropping frames
17:24
Bertl
this is rather easy to detect as we have frame counter information in the 'corner' points
17:24
Bertl
note that this is done via the overlay, so it doesn't have to be the corners :)
17:25
Bertl
I also started to rethink and redesign the scan and HDMI logic because I plan to finally fix HDMI for good in the near future
17:26
Bertl
found a bunch of interesting articles and researched some projects which also had some issues with proper HDMI and there are enough clues available to hopefully get it right :)
17:26
Bertl
that's it from my side for this week
17:28
se6astian
sunds great
17:28
se6astian
*sounds
17:28
se6astian
many thanks
17:28
se6astian
so last chance, anyone with project news? :)
17:29
se6astian
many thanks all participants! MEETING CONCLUDED!
17:44
vup
Bertl: se6astian which firmware is currently on the PICs on the beta se6astian is using?
17:47
Bertl
Nov 24 2020
17:47
vup
do you have a link to the source code?
17:49
Bertl
not at hand, but we can upgrade/downgrade the pic firmware to whatever you like as long as it uses the 0x4x 0x6x scheme
17:50
se6astian
Shall I Boot it up?
17:50
se6astian
Cooking currently so you can use it
17:52
vup
se6astian: sure I can take a quick look
17:54
vup
Bertl: Hmm well as long as its compatible with the 0x4x 0x6x scheme it should be fine obviously

Hello there :)

hi Nicolas42!
22:04
Nicolas42
Glad to join the team!
22:05
Nicolas42
I am just getting up to speed with the Beta
22:12
Bertl
hey, how's going?
22:17
Nicolas42
Bertl: pretty good, now that we got the camera going, thanks to your help :-)
22:18
Bertl
great! so everything working as expected?
22:24
Nicolas42
So far so good!
22:24
Nicolas42
You asked us by email what kind of Ethernet switch we use to connect to our Linux Desktop:
22:24
Nicolas42
Netgear GS105
22:25
Bertl
good choice!~

Anybody has suggestions for alternatives to the small fan mounted on the MicroZed in the dev kit? I know this may sound like a minor concern but... the one we have is really loud.
22:48
Dest123
left the channel
23:17
Bertl
Nicolas42: unfortunately the tiny fans are all quite noisy and they do not really last very long either
23:18
Bertl
the best choice here is to use a larger fan mounted on top of the Beta (over the PCBs) to cool the PCBs and the Zynq
23:18
Bertl
(this is also how we will have it on the ABCP enclosure
23:19
Bertl
)
23:19
Bertl
but it should be easy to 3D print something for the devkit
23:20
Bertl
note that it is also advantageous to power the fan from an external power supply if that is an option
23:31
Nicolas42
yes, we can consider another power supply just for the fan. Custom 3D print parts are definitely on the table for us too.
23:35
Bertl
so probably an 80mm of 90mm fan would be a good choice, they are reasonably popular and you can pick one which is extremely silent
23:36
Bertl
together with a power supply and some kind of speed regulation you can optimize the cooling to noise ratio
23:36
Nicolas42
Sounds good!
