MEETING TIME!
16:00
se6astian
who is here?
16:00
Bertl
is here ...
16:02
tpw_rules
hi i am here for once
16:02
Bertl
who are you? :)
16:03
se6astian
tpw_rules: any news from you to share?
16:03
vup
is here
16:03
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?
16:04
vup
we should have a setup for that now
16:04
tpw_rules
ok, how do i get access?
16:05
vup
ill msg you how to connect, I assume using the same ssh key as always is fine?
16:05
tpw_rules
yes
16:05
vup
great
16:06
tpw_rules
there should be two on the beta, but i can add the other if you add one
16:06
vup
ok
16:07
se6astian
vup/anuejn any news from your side? I see lots of commit messages in the last few days
16:07
vup
sure a bit
16:08
vup
finally got to merge the subpass rendering into narui (https://github.com/apertus-open-source-cinema/narui/pull/15)
16:08
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
16:09
vup
finally I also did some various bug fixes for axiom-firmware
16:09
vup
so the CI now runs through on main again and we should get up to date releases again
16:10
vup
(you can find that here: https://github.com/apertus-open-source-cinema/axiom-firmware/pull/186)
16:10
vup
thats it from me
16:10
se6astian
great, many thanks
16:10
se6astian
should the new release now detect my powerboard version?
16:11
se6astian
and run through axiom-start?
16:11
se6astian
or does that still require investigation?
16:11
vup
unclear
16:11
vup
I did not have the time yet to look at the changes of the new powerboard version
16:12
se6astian
ok, let me know if I can supply/do anything in that regard
16:12
se6astian
BAndiT1983: any news from your side?
16:13
BAndiT1983
nope, not really, some research for remote and SAME70
16:14
se6astian
ok then quick updates from me
16:14
se6astian
and if nobody else wants to share anything closing words from bertl as usual :)
16:14
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
16:15
se6astian
further recording/conversion/finetuning in that regard is ongoing, maybe bertl wants to say something about the UHD -> 4K hdmi upgrade afterwards
16:16
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
16:17
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
16:17
se6astian
we will discuss details next week probably
16:18
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
16:18
se6astian
its a rather brief application and rather small grant
16:19
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
16:19
se6astian
thats all I can remember from my side currently
16:19
se6astian
anyone else ready to share now? otherwise Bertl please do!
16:20
Bertl
yeah, it seems our intern is missing out today ...
16:20
Bertl
let's hope that will get better soon ...
16:20
Bertl
I was mostly busy with improving the raw HDMI transfer and testing various modes
16:21
Bertl
for this purpose, I adapted the generator setup to calculate the register settings from a simple timing data array
16:22
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
16:22
Bertl
this was mainly done to test more atypical modes like 2048x1080 and of course the 2048x1536 which contains the entire sensor data
16:23
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
16:24
Bertl
so around 388-390MByte, the Magewell capture tool starts dropping frames
16:24
Bertl
this is rather easy to detect as we have frame counter information in the 'corner' points
16:24
Bertl
note that this is done via the overlay, so it doesn't have to be the corners :)
16:25
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
16:26
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 :)
16:26
Bertl
that's it from my side for this week
16:28
se6astian
sunds great
16:28
se6astian
*sounds
16:28
se6astian
many thanks
16:28
se6astian
so last chance, anyone with project news? :)
16:29
se6astian
many thanks all participants! MEETING CONCLUDED!
16:44
vup
Bertl: se6astian which firmware is currently on the PICs on the beta se6astian is using?
16:47
Bertl
Nov 24 2020
16:47
vup
do you have a link to the source code?
16:49
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
16:50
se6astian
Shall I Boot it up?
16:50
se6astian
Cooking currently so you can use it
16:52
vup
se6astian: sure I can take a quick look
16:54
vup
Bertl: Hmm well as long as its compatible with the 0x4x 0x6x scheme it should be fine obviously

Hello there :)

hi Nicolas42!
21:04
Nicolas42
Glad to join the team!
21:05
Nicolas42
I am just getting up to speed with the Beta
21:12
Bertl
hey, how's going?
21:17
Nicolas42
Bertl: pretty good, now that we got the camera going, thanks to your help :-)
21:18
Bertl
great! so everything working as expected?
21:24
Nicolas42
So far so good!
21:24
Nicolas42
You asked us by email what kind of Ethernet switch we use to connect to our Linux Desktop:
21:24
Nicolas42
Netgear GS105
21:25
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.
21:48
Dest123
left the channel
22:17
Bertl
Nicolas42: unfortunately the tiny fans are all quite noisy and they do not really last very long either
22:18
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
22:18
Bertl
(this is also how we will have it on the ABCP enclosure
22:19
Bertl
)
22:19
Bertl
but it should be easy to 3D print something for the devkit
22:20
Bertl
note that it is also advantageous to power the fan from an external power supply if that is an option
22:31
Nicolas42
yes, we can consider another power supply just for the fan. Custom 3D print parts are definitely on the table for us too.
22:35
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
22:36
Bertl
together with a power supply and some kind of speed regulation you can optimize the cooling to noise ratio
22:36
Nicolas42
Sounds good!
