MEETING TIME, who is here?
17:00
Bertl
is here ...
17:01
se6astian
any news to report Bertl?
17:02
Bertl
well, I missed to report the completion of the four Betas last week (or maybe even the week before that ;)
17:02
se6astian
that was great news indeed
17:02
Bertl
and there is some progress on the contract work for LAM/INT
17:02
se6astian
2 have already shipped by now
17:03
se6astian
one today
17:03
se6astian
one last week
17:03
se6astian
can you tell us more about the sequencer work for LAM?
17:04
Bertl
sure, first I created a test/work environment for the required changes to the FPGA as well as kernel side
17:04
Bertl
this included updating to a recent Linux kernel (5.16.11) as well as having native compile support for driver and userspace testing
17:05
Bertl
the first step was to get the interrupts working and tested, which has already been completed last week, so we now can trigger PL-PS interrupts which is what we need to move the sequencer to kernel/userspace
17:06
Bertl
for the Linux side, I'm currently working with the UIO interrupt driver which allows to handle those interrupts in userspace (with a generic kernel driver)
17:07
Bertl
the FPGA sequencer has been removed already too and I'm currently shuffling around the registers spaces to accomodate for the changes
17:08
Bertl
timing wise tests look good, we can 'respond' in userspace within 25 HDMI pixel which should be more than sufficient to switch the buffers around
17:09
Bertl
still needs some testing to confirm that we can do a userspace solution here (which would be optimal) but if not, we can still do a kernel driver which handles the switching
17:09
Bertl
that's it from my side for this week
17:11
se6astian
great, many thanks for the update
17:11
se6astian
quick updates from my side
17:11
se6astian
we have been added to https://projects.openhardware.science/ today
17:11
se6astian
apparently we did not get the GOSH funding as we did not receive any email notification and the thread also has not been udpated ;(
17:12
se6astian
I did some wiki housekeeping to clean up the GSoC pages
17:12
se6astian
also the website workgroup met last week and made some progress with new templates and samples (bandit helped with CSS
17:12
se6astian
samples

17:14
se6astian
the workgroup will meet again on thursday
17:14
se6astian
oscar sent me some pictures of 3d print progress but will wait for him to share those in the group when ready
17:15
se6astian
manfred also sent me picture of the laser cut ZIF frame
17:15
se6astian
cutting works great with the dvd case material
17:15
se6astian
engraving not so much
17:15
se6astian
as its black on black, so not really readable
17:16
se6astian
but we can just label it another way, no big deal
17:16
se6astian
I will visit manfred soon to supply him with more dvd cases and to test the ZIF socket glueing
17:17
se6astian
thats it from my side
17:17
se6astian
anyone else who wants to report/share?
17:20
se6astian
ok, then, thanks Bertl! and I hope to see more progress reports again soon, MEETING CONCLUDED
17:23
Bertl
as usual, thanks for the moderation!
17:25
se6astian
as usual, my pleasure :D
