meeting time!
16:03
vup
is here
16:03
se6ast1an
bluez_[m]: please go ahead
16:03
metal_dent[m]
is present
16:03
bluez_[m]
thanks!... hi everyone
16:04
bluez_[m]
so this week i spent my time looking for a solution for the driver to work also with the analog switch in the new powerboards
16:04
Bertl_oO
changed nick to: Bertl
16:04
Bertl
is here ...
16:05
bluez_[m]
initially the plan was to make a separate driver for it... but fortunately i stumbled upon an already existing driver that did that called i2c-mux-gpio
16:05
bluez_[m]
so i just had to put things together and describe everything in devicetree overlay...and it worked like a charm!
16:06
bluez_[m]
https://github.com/Swaraj1998/axiom-beta-rfdev
16:06
Bertl
excellent!
16:06
bluez_[m]
i added the dt overlays to the repo as well.. and updated readme
16:07
anuejn
is here
16:07
bluez_[m]
m happy that finally the driver works with all the mux/switches... so after all these important things done i can finally focus on the openocd side
16:08
se6ast1an
nice!
16:08
bluez_[m]
there have been many unexpected delays ik... this time its for sure...i guess ':D
16:08
bluez_[m]
so thats it from me!!
16:09
bluez_[m]
thanks bertl and sebastian :)
16:09
se6ast1an
many thanks, metal_dent[m] please go ahead
16:09
metal_dent[m]
hi everyone!
16:10
metal_dent[m]
last week was pretty good, the communication was already established between the remote and the host PC so i added the sequence number and checksum checking functionalities too
16:11
metal_dent[m]
the command string (or data) coming from PC already has sequence number and checksum so on the remote side also they are calculated and compared and only then a positive acknowledgement is sent
16:12
metal_dent[m]
after receiving "ACK" the hex data from the chip is read (or write into, according to the command), so more than majority of the work is done!
16:13
metal_dent[m]
although there is some delay but mostly due to the obstacles i faced in the last phase
16:13
metal_dent[m]
that's it from me :)
16:14
se6ast1an
many thanks!
16:14
se6ast1an
what are your next steps now?
16:15
metal_dent[m]
now with the command string the name of the chip and the command (read or write) is sent so accordingly i just have call the methods (the chip selection and read/write methods are already present in the code)
16:15
BAndiT1983
don't forget continuous data, which has come through the USB connection, this is not to underestimate
16:16
metal_dent[m]
oh yes
16:16
se6ast1an
right! preetimenghwani[ your turn, please go ahead
16:17
preetimenghwani[
Hello Everyone
16:17
preetimenghwani[
I spent last week debugging the reduced framework, now the framework works as expected.
16:18
preetimenghwani[
I have also extended it for two writers
16:18
preetimenghwani[
Now i will be starting with the task of doubling the throughput
16:19
preetimenghwani[
For that i will be discussing the ideas with Bertl. Thats it from me!
16:19
Bertl
great!
16:19
preetimenghwani[
Thanks!
16:19
Bertl
how is the status of the alternate remapping?
16:19
Bertl
i.e. RGRGRG .... / GBGBGB... instead of RGGB RGGB ...
16:20
Bertl
just curious because we might make good use of that soon if available
16:20
preetimenghwani[
okay, so currently i am using RGRGRG...../GBGBGB format
16:21
preetimenghwani[
sorry i mean RGGB
16:21
preetimenghwani[
We can discuss about the ideas after the meeting
16:22
preetimenghwani[
I had a few questions to ask
16:23
se6ast1an
right, sounds like a good after meeting task
16:23
se6ast1an
vup/anuejn would you be so kind an tell us about the hackathon progress so far?
16:23
se6ast1an
vup and anuejn are in vienna for pretty much exactly one week now
16:23
se6ast1an
working on very interesting AXIOM things
16:23
anuejn
we have worked on multiple things so far:
16:24
earabul
joined the channel
16:24
anuejn
we did some development on the usb3 plugin modules / the ft601
16:25
anuejn
there we did some performance tests which showed that we can transfer about 360Mbytes reliably in one direction (without data loss)
16:26
anuejn
then we implemented a libusb based rust library to interface with the ft601 to avoid the propriatery lib ftdi provides (https://github.com/apertus-open-source-cinema/ft60x-rs)
16:28
anuejn
currently we are working with Bertl on integrating that into the beta gateware and writing gateware for the machxo2 on the plugin module
16:29
anuejn
we also worked on extending our infrastructure that lets us read / write CSRs inside an FPGA to support transport over JTAG
16:29
anuejn
this will hopefully help us while debugging code in the plugin module or the hdmi digitizer
16:30
anuejn
the usb3 on the digitizer was also tested (same chip; similiar gateware)
16:31
anuejn
we now need to configure / use the gigabit transcievers on the HDMI digitizer to make progress on that project
16:32
Bertl
maybe mithro or _florent_ are interested to help there?
16:32
vup
furthermore we worked on some fw2.x improvements
16:33
vup
we added replaced devmem2 with memtool, as the former was producing unexpected behaviour in some cases
16:33
vup
the script names were renamed to have consistent names between internal usage and user facing usage
16:34
vup
furthermore we finally merged nctrl and the webui into the main branch of fw2.x
16:35
vup
with these two, one can now for example plug a wifi stick into the beta and set the exposure time and analog gain from a web interface
16:36
vup
thats it probably
16:37
se6ast1an
for testing this with more wifi sticks your help would be appreciated, if you have a wifi stick and a raspberry pi for example and you know the wifi stick works under linux like the raspi AND has soft-ap capabilities please let me know
16:37
se6ast1an
I will order it and test for compatibility in the beta
16:37
se6ast1an
many thanks vup/anuejn, a very successful/busy week
16:37
se6ast1an
quick update from me:
16:38
se6ast1an
I benchmarked our injection mold heat sink for the axiom beta developer kit
16:38
se6ast1an
https://cloud.apertus.org/index.php/apps/gallery/s/j5fyMy25r6D8Lgi
16:38
se6ast1an
and while matching 40x40 fans still need to be ordered I tried a general purpose 60x60 fan for now to see if the temperatures stay within the operation range of the Zynq
16:38
se6ast1an
which lists 85°C as max operating temperature
16:39
se6ast1an
which we seem to easily stay below, without fan we get dangerously close to it
16:39
se6ast1an
but as long as there is a bit of airflow it seems to be working fine
16:39
se6ast1an
further tests and suitable fans will follow
16:40
se6ast1an
and comparison to the cnc milled heatsink + 30x30 fan as currently used in the ABDK as requested by Bertl
16:40
se6ast1an
Bertl would you be so kind and finish us off again? :)
16:40
Bertl
does another special move ... *ba-zing*
16:41
Bertl
well, I spent most of my time with hardware last week
16:41
Bertl
first, I updated the remote hardware configuration of the remote betas
16:41
Bertl
so we now have one version of each power board available for testing
16:42
Bertl
(the PCA9540, PCA9543 and the Analog Switch)
16:43
Bertl
in this process, I also updated the betas to fw 2.x so that we can test this as well
16:43
Bertl
I also built myself a minimalistic partial Beta to test the firmware changes for the usb3 interface
16:44
Bertl
for this, I also updated to vivado 2020.1 and quickly hit a bug/feature there which seems to increase the build time exponentially :/
16:45
Bertl
there was also some progress on the IMU side, we also have a test setup for that now
16:45
Bertl
and hopefully we will have some data from the sensors soon
16:46
Bertl
that's it from my side for this week!
16:46
se6ast1an
any news on the automatic prober script and new PB assembly?
16:47
Bertl
not much new there, I did write a few lines on the gcode interface though
16:48
se6ast1an
ok, I assume after the hackathon we should give that #1 priority again
16:48
Bertl
yes, that's the plan so far
16:49
se6ast1an
many thanks!
16:49
se6ast1an
anyone else with topics to discuss or reports to share?
16:49
se6ast1an
apoorva_arora: ?
16:51
se6ast1an
ok then
16:51
se6ast1an
MEETING CONLUDED
16:51
se6ast1an
many thanks everyone
16:51
se6ast1an

hello everyone!!! can anyone help me regarding contribution in open source projects please
18:35
BAndiT1983
hi Pragya
18:35
BAndiT1983
what is your area of interest?
18:35
Pragya
web development
18:35
Pragya
can you please help
18:37
BAndiT1983
you can talk to vup or anuejn / anu3jn as they are currently developing the web interface for the camera
18:40
Pragya
thanks for the information
18:41
Pragya
can they help me if they are free for sometime
18:42
BAndiT1983
probably, as they have the details about the setup and environment of it
18:43
