TT article draft is ready for release and will be published after we finish this meeting
16:05
se6astian
will visit bertl on Friday to exchange more beta hardware among otherr things
16:05
se6astian
for the remote access setup
16:05
se6astian
as it turned out the assembled dev kit here needs a tiny solder modification for the 5V fan to operate
16:09
se6astian
ok, thats it from me
16:09
se6astian
Bertl: any news from your side?
16:09
Bertl
yes, actually there are some news here ...
16:10
Bertl
now that I have a working Axiom Beta Dev Kit here, I started testing the MageWell USB Device (the new one)
16:10
Bertl
and did some test runs with a test pattern, to see how reliable the connection and digitization process is in general
16:11
Bertl
preliminary testing shows that with a proper (high quality) HDMI cable which isn't too long, we get really good results
16:11
Bertl
my longest test was about four hours of continuous transfer
16:12
Bertl
and we 'only' lost about 50 frames at 60FPS
16:12
Bertl
note that this was on my working machine, so no dedicated capture PC or so and I was doing normal work during that time
16:13
Bertl
it also showed that with a not-so-good cable, which still gives perfecly fine image
16:13
Bertl
we get easily one error per second during the transfer
16:13
Bertl
TL;DR high quality cabling is a must
16:14
Bertl
on the software side, I installed the brand new Vivado 2021.1 which seems to have changed in a number of ways
16:15
Bertl
means: our existing gateware doesn't even build with it
16:15
se6astian
oh my
16:15
Bertl
but after some hours of checking and adjusting stuff, I've now got a clean gateware build which actually works
16:15
se6astian
hurray!
16:16
Bertl
and, the best for the last, I've already done a raw transfer implementation there, it just needs to be tested :)
16:16
Bertl
that's it from my side for this week
16:17
se6astian
woah! thats great!
16:17
Bertl
ah, maybe I should mention, the new gateware can in theory transport 2160p60
16:18
Bertl
(over two HDMI digitizer that is)
16:18
se6astian
did you also implement preview on one and raw on other hdmi output?
16:19
Bertl
yes, the gateware uses both plugin slots as HDMI and you can select which one outputs what
16:19
se6astian
so from friday on I should be in a good position to conduct these tests and also provide a remote access setup for other devs
16:19
se6astian
wonderful news!
16:19
Bertl
so basically one of 'normal HDMI', raw channel A/B or alternating A/B
16:20
se6astian
I read that isabell has a python script prototype already that could be tested to convert first A+B frames to 1x raw12
16:21
Bertl
yes, although it might be rather slow
16:21
se6astian
sure, we can speed it up once we know its working
16:21
Bertl
anyway, conversion from the capture to raw will be part of my work, as I need that for testing
16:21
se6astian
right
16:22
se6astian
sounds great
16:22
se6astian
anyone else, last chance to report?
16:26
vup
has nothing to report this week
16:28
se6astian
alright
16:29
se6astian
