16:00 | se6ast1an | Meeting time!
| |
16:00 | se6ast1an | who is here?
| |
16:01 | bluez_[m] | * bluez_ is here
| 16:01 | Bertl | is here ...
| 16:01 | metal_dent[m] | is here
|
16:01 | se6ast1an | great
| |
16:02 | se6ast1an | please go ahead metal_dent[m] with the first report
| |
16:03 | metal_dent[m] | hi everyone!
| |
16:03 | metal_dent[m] | so last week we had our evaluation period, so most of the time i spent on cleaning up my code and writing the report
| |
16:03 | metal_dent[m] | here is the link to my report -> https://drive.google.com/file/d/1nQ-_JvAXN7mp_bf8QzQ4n6gFnLUhusPy/view?usp=sharing
| |
16:05 | metal_dent[m] | also we decided to scrap off my ProcessCommand() method as it was giving a lot of trouble, so now i've divided the method into smaller sub-methods to ease any debugging process
| |
16:06 | metal_dent[m] | and also changed my python script to decrease the command string length (made it more compact), this also i have done so as to recognise the string parts (command, sequence number, checksum, fields etc) easily
| |
16:07 | metal_dent[m] | so the communication between the host PC and remote is almost established now!! just a few more testing should be done and after that it's good to go :)
| |
16:07 | metal_dent[m] | that's it from me! thank you
| |
16:08 | se6ast1an | many thanks!
| |
16:08 | se6ast1an | bluez_[m] you are next, please share your report with us
| |
16:08 | bluez_[m] | thanks! here is my report -> https://drive.google.com/file/d/1XxUCo4E4EjMdfU9HKhAgaJ09wq88L1E8/view?usp=sharing
| |
16:09 | bluez_[m] | so finally the issue that my driver could not be probed when used with the mux... is not resolved!
| |
16:09 | bluez_[m] | s/not/now
| |
16:09 | Bertl | *phew*
| |
16:09 | bluez_[m] | i updated the code as well as readme
| |
16:10 | bluez_[m] | https://github.com/Swaraj1998/axiom-beta-rfdev
| |
16:10 | bluez_[m] | Bertl: sry xD
| |
16:10 | bluez_[m] | now the two mxo2s can be separately dealt with
| |
16:10 | bluez_[m] | for the older power boards that is
| |
16:11 | bluez_[m] | the ones with pca9540 mux
| |
16:11 | bluez_[m] | so this week ill be focusing on implementing the support for other powerboards as well
| |
16:11 | bluez_[m] | with different muxes/switches
| |
16:12 | bluez_[m] | and possibly also change the pic firmware with bertl so that we can configure jtag ports with just a simple command through i2c bus
| |
16:12 | bluez_[m] | thats it from me!
| |
16:12 | se6ast1an | many thanks!
| |
16:13 | se6ast1an | preetimenghwani[: please go ahead
| |
16:13 | preetimenghwani[ | Hello everyone, this week i mostly spent in debugging the minimal framework, as when i tried extending the minimal framework for 64 sensel mode there were some issues.
| |
16:14 | preetimenghwani[ | I also tried adding 64sensel mode to whole pipeline but there were some issues with that too.
| |
16:15 | preetimenghwani[ | So currently focussing on debugging the minimal framework as adding 64sensel mode in that would be easier.
| |
16:15 | preetimenghwani[ | And here is my report:https://drive.google.com/file/d/1_UC7dNhAV7MBLd9xbt8p9yChvfFqvSo4/view?usp=drivesdk
| |
16:15 | preetimenghwani[ | Thats it from me!
| |
16:16 | se6ast1an | many thanks!
| |
16:16 | se6ast1an | quick update from me:
| |
16:17 | se6ast1an | the hackathon started: vup and anuejn have arrived in vienna yesterday and are sitting next to me now at the factoryhub
| |
16:17 | se6ast1an | I benchmarked a few ssds with the ultra96-v2 connected over USB3 last week
| |
16:18 | se6ast1an | here is a screenshot from current results: https://paste.pics/9Q689
| |
16:19 | se6ast1an | unfortunately the datarate from single ssd does not double with two connected
| |
16:19 | se6ast1an | best results were 424MB/s with two SSDs
| |
16:20 | se6ast1an | single SSD best result was 270MB/s
| |
16:21 | se6ast1an | now I started evaluating the cooling capabilities of our injection molded heat sink part: https://www.apertus.org/sites/default/files/Injection_Moulding_02-small.jpg
| |
16:21 | se6ast1an | no results on wiki yet but the setup stands and the script to record temperatures works
| |
16:21 | se6ast1an | done from my side
| |
16:21 | se6ast1an | vup/anuejn?
| |
16:22 | vup | well anu3jn and me sucessfully arrived in vienna
| |
16:22 | vup | for now we starned working on th usb3 plugin module again
| |
16:22 | Dest123 | left the channel | |
16:22 | Bertl | yay!
| |
16:23 | vup | it uses a ft601 fifo to usb3 chip to bring the live video to a computer where it can be recorded
| |
16:23 | vup | unfortunately it seems difficult to acheive the advertised datarate for some reason
| |
16:23 | Bertl | https://wiki.apertus.org/index.php/1x_USB_3.0_Plugin_Module
| |
16:24 | Dest123 | joined the channel | |
16:25 | vup | so now we are trying once again, this time without the proprietary fdti driver, which hopefully eliminates one slow part
| |
16:25 | vup | I think thats it from me
| |
16:25 | se6ast1an | great!
| |
16:26 | se6ast1an | Bertl: please finish us :)
| 16:26 | Bertl | does a special move ...
|
16:27 | Bertl | well, the last week, besides the second evaluation, I did mostly work on hardware again
| |
16:27 | Bertl | the remote setup was somewhat rearranged and now features three partial betas
| |
16:27 | Bertl | the unused remote was removed to make some space there
| |
16:28 | Bertl | the partial betas also contain various shields and CSOs to allow for testing, debugging and experimentation
| |
16:29 | Bertl | I also assembled the necessary hardware for the third beta as well as special hardware to low level digitize HDMI signals
| |
16:29 | Bertl | http://vserver.13thfloor.at/Stuff/digitizer_03.jpg
| |
16:29 | Bertl | (this is an intermediate state, the hardware is now completely assembled)
| |
16:30 | Bertl | and today I'm at the hackathon in Vienna ...
| |
16:30 | Bertl | that's it from me for this week
| |
16:30 | se6ast1an | great, thanks!
| |
16:30 | se6ast1an | anyone else who wants to report ?
| |
16:31 | se6ast1an | apoorva_arora: ?
| |
16:31 | bluez_[m] | can i ask...what exactly is an HDMI digitizer? ':D
| |
16:32 | bluez_[m] | i mean where will it be used?
| |
16:33 | Bertl | yeah, digitizer might be a little confusing
| |
16:34 | bluez_[m] | ah, alright alright
| |
16:34 | Bertl | the design is based on the Trenz TE0714 module
| |
16:34 | Bertl | which is basically an Artix module with multi gigabit tranceivers
| |
16:34 | Bertl | the idea is to have high speed input and output compatible with HDMI (i.e. CML)
| |
16:35 | Bertl | so that we can test various aspects of HDMI output and input
| |
16:35 | Bertl | the problem so far is that we do not exactly know how our HDMI signal is received at the lowest layer
| |
16:36 | Bertl | and thus we want to capture the signal with the Artix MGTs to further analyze it
| |
16:36 | bluez_[m] | ah, i see
| |
16:37 | Bertl | so I just called it digitizer for now, the official name is more like TE0714 HDMI interface bord :)
| |
16:37 | Bertl | *boatrd
| |
16:37 | Bertl | *board
| |
16:37 | bluez_[m] | yea cuz google search for hdmi digitized did not land me anywhere xD
| |
16:38 | bluez_[m] | alright thanks! now please continue with the reporting (anyone?)
| |
16:38 | se6ast1an | very good input indeed bluez_[m]!
| |
16:39 | se6ast1an | I think we are done for today
| |
16:39 | se6ast1an | meeting concluded, many thanks everyone who attended!
| |
16:39 | bluez_[m] | thanks!
| |
16:43 | kbeckmann | sorry for barging in here but what issues are you having with HDMI?
| |
16:47 | Bertl | the problem here is that we have had some issues with specific hardware, e.g. Atomos Shogun and the CamLink4K
| |
16:48 | Bertl | where we had to adjust our sync signals in 'unexpected' ways to make it work
| |
16:48 | Bertl | as this doesn't make much sense to us, we suspect some non-trivial problems in the HDMI we generate
| |
16:48 | Bertl | and that is mainly why we want to investigate this further
| |
16:51 | kbeckmann | oh okay. so this board will act as a sniffer where you get the raw 8b10b encoded data stream?
| |
16:51 | vup | yep
| |
16:52 | kbeckmann | i was thinking of building exactly this board but with an ecp5 but got stuck with other projects :)
| |
16:52 | kbeckmann | good luck and hope you can find your issue.
| |
17:02 | Bertl | thanks!
