09:35 | se6ast1an | BAndiT1983: panintended so in 25 minutes or in 1h25?
| |
09:35 | panintended | Hi all
| |
09:37 | panintended | se6ast1an BAndiT1983 can we have it tomorrow or Wednesday 12:00 noontime UTC+2 time?
| |
09:37 | se6ast1an | I am at the university then but should work still
| |
09:40 | panintended | We can agree on another time as well. It's fine by me so long as I plan it. Another possibility would be today 17:00-18:00 UTC+2 for example.
| |
09:40 | panintended | I'd like to brush up on stuff related to the meeting so that I'm prepared and we can keep the meeting short and efficient for everyone.
| |
09:40 | panintended | What items will we discuss by the way?
| |
09:45 | BAndiT1983 | no problem from my side, am working usually and won't leave at that time
| |
09:46 | BAndiT1983 | am a bit out of the firmware topic, so would have also to check what's on the list, was looking more into BL-related stuff lately, but also occupied by other things a lot
| |
09:50 | se6ast1an | today before or after the IRC meeting is fine as well
| |
09:50 | se6ast1an | main topic would be remote firmware and observer pattern remaining todos, next steps
| |
09:57 | BAndiT1983 | ok, i should be back till the meeting, will leave for an appointment after work
| |
10:03 | se6ast1an | panintended: please choose :)
| |
10:05 | panintended | Ok, let's go with 17:00-18:00 utc+2 time today if it's ok with everyone
| |
10:09 | BAndiT1983 | won't work for me, as the appointment is at 16:00, don't know if i will back by then, but you both can discuss stuff and i can read and comment the logs later
| |
10:12 | se6ast1an | and tomorrow noon?
| |
10:24 | BAndiT1983 | every noon while from monday to friday is ok for me
| |
10:24 | se6ast1an | then lets do tomorrow around noon7
| |
10:25 | se6ast1an | ?
| |
10:31 | panintended | Yes, fine by me!
| |
10:31 | panintended | Tomorrow 12:00 UTC+2
| |
10:46 | se6ast1an | can we do 13:00 utc+2 so I can go to lunch with my university colleagues?
| |
11:00 | BAndiT1983 | should be possible
| |
11:07 | se6ast1an | appointment noted
| |
11:08 | se6ast1an | also ok fr you panintended?
| |
11:08 | se6ast1an | *for
| |
11:09 | panintended | Yes, ok for me too
| |
11:09 | se6ast1an | great, noted
| |
12:38 | se6ast1an | first cp enclosure fan test results are in: https://paste.pics/9LTS7
| |
12:39 | se6ast1an | just spotted one wrong marker though :)
| |
12:43 | se6ast1an | conclusion: just a small amount of airflow works to keep everything well within the healthy operation temperature range
| |
12:45 | BAndiT1983 | nice!
| |
12:47 | BAndiT1983 | se6ast1an: do you mean: "already a small amount of airflow"?
| |
13:17 | se6ast1an | yes
| |
13:17 | se6ast1an | thanks
| |
13:21 | BAndiT1983 | ah, was just not sure at first
| |
13:21 | BAndiT1983 | am off for a moment, will be back later

14:57 | Bertl | mroning folks!
| |
14:57 | Bertl | *morning
| |
14:58 | se6ast1an | good morning
| |
15:04 | Bertl | se6ast1an: why is the power board temperature so 'blocky'?
| |
15:05 | se6ast1an | because "cat /sys/class/hwmon/hwmon0/temp1_input" only returns integer values
| |
15:05 | se6ast1an | is that not like its supposed to?
| |
15:06 | se6ast1an | divided by 1000 actually but still integer only, eg 34000, 35000...
| |
15:06 | se6ast1an | details see https://wiki.apertus.org/index.php/AXIOM_Beta/Temperatures
| |
15:09 | Bertl | well, integer values is fine, but they are in mili-degree celcsius
| |
15:09 | Bertl | for example on beta-b I see: 29500
| |
15:10 | Bertl | which means 29.5
| |
15:13 | Bertl | but your script simply throws away the fractional part
| |
15:15 | se6ast1an | ah
| |
15:15 | se6ast1an | then I need to improve it
| |
15:15 | se6ast1an | which line?
| |
15:16 | Bertl | line 36 has $(($PBTEMPRAW/1000))
| |
15:16 | Bertl | btw, it would be way better to log the raw values and do any post processing in 'post' :)
| |
15:18 | se6ast1an | ok
| |
15:18 | se6ast1an | thanks

16:00 | se6ast1an | MEETING TIME!
| |
16:00 | se6ast1an | good evening everyone, please pm me now to report in the usual manner
| |
16:01 | se6ast1an | metal_dent[m]: please go ahead
| |
16:01 | metal_dent[m] | hi everyone!!
| |
16:02 | metal_dent[m] | Last week, finally the communication problem solved and i was able to send and receive data between the remote and PC
| |
16:02 | metal_dent[m] | But after that solved i encountered another weird problem, i want to send a command string whose length was 18-20 characters
| |
16:03 | metal_dent[m] | but initially the script just hung then i found that if the length is <= 8 it was working perfectly. so i talked with BAndiT1983 and Bertl and we did some debugging and later confirmed that the python script which runs on the PC side has no problem
| |
16:03 | Dest123 | joined the channel | |
16:03 | metal_dent[m] | the problem is somewhere in the USB code or the hardware.
| |
16:03 | illwieckz | joined the channel | |
16:04 | metal_dent[m] | so for the time being i'm splitting the string in 8 characters each (or less) and sending to the remote, so one problem down!!
| |
16:04 | metal_dent[m] | now i'm comparing the sequence number and checksum on remote and the ones coming from the PC then send "ACK" (or "NACK")
| |
16:04 | metal_dent[m] | getting some problem there also but just talked with Bertl and i think it'll solved now
| |
16:05 | metal_dent[m] | *it'll be
| |
16:05 | metal_dent[m] | that's it from my side! thank you :)
| |
16:06 | se6ast1an | many thanks!
| |
16:06 | se6ast1an | bluez_[m]: your turn
| |
16:07 | bluez_[m] | tx, hi everyone!
| |
16:08 | bluez_[m] | so this week bertl and I discussed with the openocd people regarding the best way to implement the debug interface that openocd supports
| |
16:08 | bluez_[m] | https://lore.kernel.org/patchwork/cover/1223367/
| |
16:09 | bluez_[m] | ^^ they said this could be a possible implementation... currently not yet merged in linux kernel
| |
16:09 | bluez_[m] | but we can take inspiration from it and might implement something similar
| |
16:09 | bluez_[m] | but i couldn't look into this much this week
| |
16:10 | bluez_[m] | i mostly improved the driver code
| |
16:10 | bluez_[m] | https://github.com/Swaraj1998/axiom-beta-rfdev/commits/3e2910aee0796c4951cfc7160bdc1ec10f6994ae
| |
16:10 | bluez_[m] | look at the commits july 14th onwards
| |
16:12 | bluez_[m] | so majorly: i added a function to make sense of the status register bits... also added sysfs entry "statstr" to show the human readable interpretation of the status
| |
16:13 | bluez_[m] | i added code to register two fpgas... for two machxo2s...but currently both work for only one fpga which is selected by mux... so i was looking into how to handle muxes and everything
| |
16:13 | bluez_[m] | i struggled a bit to understand different muxes we have and how to use them in my driver...but i am much clear now
| |
16:14 | bluez_[m] | so this will be implemented this coming week
| |
16:14 | bluez_[m] | i also added a way to reset the fpga... currently done at driver exit
| |
16:15 | bluez_[m] | this week i will add a proper mechanism to switch between two mxo2s...and also start working on the debug interface as soon as possible
| |
16:15 | bluez_[m] | thats it from me!
| |
16:16 | se6ast1an | many thanks!
| |
16:16 | se6ast1an | preetimenghwani[: you are next, please go ahead
| |
16:16 | illwieckz | left the channel | |
16:17 | preetimenghwani[ | Thanks! Hello Everyone !
| |
16:17 | preetimenghwani[ | So I spent most of the time gathering ideas on how throughput can be doubled and other features can be added and also discussed it with Bertl.
| |
16:17 | preetimenghwani[ | It took quite some time as it required understanding of some part of the top module and a few other modules as well.
| |
16:18 | preetimenghwani[ | I added a feature of Y subsampling and tested it on hardware too.
| |
16:18 | preetimenghwani[ | Currently I am working on the task of doubling the throughput, also working on minimal framework which will be required for testing it.
| |
16:18 | preetimenghwani[ | ( I have added the project to wiki )
| |
16:19 | preetimenghwani[ | Thanks a lot! Thats it from me :)
| |
16:20 | se6ast1an | many thanks!
| |
16:20 | se6ast1an | Great to see 3 projects have already been added to:
| |
16:20 | se6ast1an | https://wiki.apertus.org/index.php/GSoC_Projects
| |
16:20 | se6ast1an | megora and apoorva_arora whats your status?
| |
16:22 | se6ast1an | quick updates from me: I have been busy with temperature benchmarking in the AXIOM Beta CP enclosure with a 12V fan. There are more fans to test and of course its also interesting to see how each fan performs at different voltages and also how loud it is at such voltages. Documentation is work in progress here: https://wiki.apertus.org/index.php/AXIOM_Beta/Temperatures
| |
16:22 | apoorva_arora | ill update the wiki today
| |
16:22 | se6ast1an | great!
| |
16:22 | se6ast1an | any updates for us here as well?
| |
16:23 | apoorva_arora | Thanx, I spent most of the time in understanding how PS PL communuication over AXI works as I want to use the concept for testing. After spending lot of time and following a tutorial i incorporated my design a custome axi lite peripheral using vivado toolchain. I plan to use a baremetal code to test input output registers on ZYNQ.
| |
16:23 | apoorva_arora | meanwhile i started working on the third phase of the design
| |
16:23 | apoorva_arora | i.e scheduler
| |
16:24 | apoorva_arora | that schedules the incoming requests as per priority.
| |
16:24 | apoorva_arora | i implemeted the basic structure (https://github.com/Apoorva-ar/GSOC_2020/blob/master/Scheduler_master.vhd) and will be conducting testbench simulations today.
| |
16:25 | apoorva_arora | but ,main focus in the coming two weeks will be axi based hardware testing.
| |
16:25 | apoorva_arora | thats all from my side
| |
16:25 | se6ast1an | many thanks!
| |
16:26 | apoorva_arora | also can i use the axi perpheral from vivado toolchain?
| |
16:26 | Bertl | is it open source?
| |
16:26 | apoorva_arora | it is generated from tool itself and doesnt mention anything on the code
| |
16:27 | apoorva_arora | but i will have to see data sheet of the software to verify that
| |
16:27 | Bertl | needs to be at least a FOSS/OH compatible license
| |
16:27 | apoorva_arora | unlike lattice where they had specified on the code itself
| |
16:28 | apoorva_arora | okay i will look into that
| |
16:28 | Bertl | but there are several open source alternatives for an AXI lite peripherial
| |
16:28 | Bertl | (e.g. the one we use in the Beta gateware or the nMigen one)
| |
16:29 | apoorva_arora | okay
| |
16:29 | apoorva_arora | also
| |
16:29 | apoorva_arora | when we write data to an address via software
| |
16:30 | apoorva_arora | is the AXI master port on ZYNQ generating valid data signal
| |
16:31 | apoorva_arora | whenever software makes an update to the address
| |
16:31 | Bertl | not sure what you mean by that, but any write to one of the peripherial addresses will result in an AXI transaction between PS and PL
| |
16:32 | apoorva_arora | okay
| |
16:32 | se6ast1an | no updates from Bertl and BAndiT1983 today.
| |
16:33 | se6ast1an | We will host a hackathon with vup and anuejn in Vienna the first two weeks of August, some areas of work for the event: Micro V3 hardware, webui & nctrl <-> remote integration, Firmware 2.0 and maybe some nmigen gateware work.
| |
16:33 | se6ast1an | anyone else who wants to report?
| |
16:34 | se6ast1an | right then, quick meeting today :)
| |
16:34 | se6ast1an | many thanks to all participants!
| |
16:35 | se6ast1an | meeting concluded
