Tanmay,
For me anyway, your voice cut out after you shared your screen. It was fine when you were showing your slides.
I hear Tanmay's voice the whole way through. It's a bit quiet... let me see what I can do with audio editing to boost it... not sure if there will be clipping though at the max amplitudes, as I did get some buzzing when I boosted my speaker volume to hear him.
Hi Nathalie,
The files I uploaded are in .mov format, and I use "QuickTime Player" to play video. It is working fine for me. I believe converting to .mp4
might help. I will see if I can find a way convert it.
We have more time now and we don't need to fit in the 10 min slot but we still need to fit your section in ~15 min. Your video is already 16 min, if you add more demos to it, it is going to be 20 min or more. That is tool long. You may have to pick what you show and leave the others
I believe showing matrix_multiplication and proxy_app is enough in that case.
echo_test is similar to matrix_multiplication. One thing I wanted to show was split mode, but it is not demonstrating any OpenAMP
functionality but just printing messages on the console. So, I believe it is fine to skip it as well.
Please let me know if any concerns with these two demos in the webinar.
for the people to explore on there own afterward.
Nathalie,
Is this what "record separately" is suppose to look like? I can't test yet as I can't share me screen on this computer.
No. Record separately will produce separate files. I have attached a PNG screenshot of how Bruce's recording shows up in my Zoom account. Dan's link also has both files uploaded from Zoom.
I am going to view Dan's & Bruce's videos before I experiment to see if editing tools can split Tanmay's file into suitable resolution components + fix audio, or if Tanmay will need to re-record, since that will be the longest of the tasks.
Hi Nathalie,
I am using zoom on Mac. I don't see following options under: zoom -> preferences -> recording
* Select: Active speaker * Select: Shared screen
I will see what works for me to generate two separate files.
Thanks,
Tanmay

Hi Nathalie and Bill,
Please find my demo video draft v1 here:
https://drive.google.com/drive/folders/1ZRe8Ajmagwg7b9NdKYEzUQrkmp3 ZnI
JK?usp=share_link It contains Slides + matrix multiplication demo + proxy app demo in lockstep mode.
If all look good, I will go with rest of the demos.
Thanks, Tanmay

Hi Bill & Tanmay, I was able to get the docker image up & running after a few tries.
I would like to understand what issues you had getting docker running. Can we improve the help?
Was not a system reference issue. I think this is the first time I've had a
VirtualBox Ubuntu VM be so problematic out of the box. Network-related issues.
Are you planning to post the known issues, or is that just a working list? I
wish I scrolled all the way down to see that hangs/panics are expected because mine failed on the first few tries (hypothesis it seems to always work the first time = FALSE), but I saw that once I got through the rest of the steps. Sounds like you are seeing a greater failure rate than I am. The original kernel was failing 25% of the time but with the pinctl patch I get a failure rate of about 6% (7 Fails out of 120 runs)
I tried once more today and that worked on the first try.
I tried something yesterday (Setting PREEMPT_NONE like Petalinux does ) that I was sure was going to fix it but it did not change the fail rate. I have spent a TON of time on this trying to get a configuration we can call "upstream" but yet works on the zynqmp. (I should have switched to doing slides earlier but ..) I will get back to this after the slides are done and the 1st recording are
done.
Hopefully OK on Monday. If it crashes when Tanmay is recording he will have to try again and we can cut that out.
Yup.

Fortunately, I was optimistic and kept exiting out & trying again a few times, then I was able to log in as root on the main UART and run demo1A and demo1B. There is also a demo1C. I was thinking about adding a demo1 script that just runs all three perhaps with the pause between them.
I tried demo1C today. When I say I don't want to repeat the demo, it stops
the application and then the last 2 lines of output are:
Host > RPC service exiting !!
Modprobe: FATAL: Module rpmsg_char is in use
Not sure if that is expected due to the application shutting down?
The hints at what to type next are nice to have, but then I got distracted
and started to follow those instead of continuing to follow the instructions in the Google document. Hopefully that is not unexpected for the user... but then in either demo1A or demo1B, was something supposed to show up
on
2nd UART R5_0? I still see
"waiting for port 1115 . Connecting"
Yes, I was intending you to just follow the instructions inside the machine. Tanmay's demo's (demo1 and demo2) do not use the 2nd UART. demo3
and
demo4 do. As I said yesterday, demo2 is now broken with the new firmware Tanmay gave me. I will try to go back to the previous firmware after our meeting today. demo3 works now. demo4 is still a placeholder for Dan's demo.
I tried demo3 today and I do see the output on 2nd UART.
It hung for me on the 3rd iteration of stopping R5_1.
I exited demo3 and tried again and it worked.
It was only once I went back to the Google document instructions and tried
the echo to /dev/ttyPS1 did my message then show up after
"Connecting".
I can add the echo statement to the first demo so something shows up.
For this instruction in the Google document: dev@openamp$ scp ~/test-sw/xilinx-lock-step/image_echo_test \ qemu-zcu102:/lib/firmware it's a little confusing because of 2 reasons: (1) the file appears to have
significance if it's going into /lib/firmware, but then we don't do anything with it (since I guess we just want to show that a file appears on the other side) and we also didn't have them check /lib/firmware to see that the file isn't one of the image_* files that was there before, and (2) now the file would be either image_echo_test_<kv260|zcu102>. So, maybe that
could
be clarified by adding a step:
dev@openamp$ ssh qemu-zcu102 root@generic-arm64:~# ls -l /lib/firmware root@generic-arm64:~# exit dev@openamp$ scp ~/test-sw/xilinx-lock-step/image_echo_test_kv260
\
qemu-zcu102:/lib/firmwareYou don't really need this to run the demo. We could move it to a backup section. I will change the scp example. I wrote that before I added the firmware to the cpio at startup. That files is already there. I will change it to something like: $ date | tee datefile $ scp datefile qemu-zcu102: $ ssh qemu-zcu102 cat ./datefile
Yes, that would be better.
Then tell them to check it appeared on the other side. The docker cleanup instructions were helpful since it's been many years
since I last used it 😊 Sounds like you missed that there are 4 demos. (5 once we add Bruce's).
Had run out of time to try stuff.
Happy US Thanksgiving!

I can change the initial message on container start. Thanks for trying it out. The feedback is helpful, Bill

Dan has given me content for his demo but it is not yet included. I have not included Bruce's demo yet. I am waiting for feedback and to see
what the SySDT slides look like.
Tanmay gave me new firmware images which are in but: >>> split mode on R5_1 is failing. <<< The docker image guides you through running Tanmay's demos on the
QEMU platform. Tanmay will also show the demos running on HW
(KV260).
Providing instructions for KV260 is optional. I will be working on Slides today and will take any feedback tomorrow (or
Thursday).
I will not be working at all on Thursday (US Thanksgiving) and will record my
video on Friday.
