EH 12:47 AM MitySOM-5CSX Embedded Vision Developer's Kit for Basler dart BCON Support: RE: Intel OpenVINO with the VDK

Thanks Mike,
That confirms what I've been thinking about it also, so that is the approach I'll take -- merge the two projects into a VDK BSP.
Thanks, and please stay safe out there in NYC..

The FPGA code for the VDK is on github here:
https://github.com/CriticalLink/mitysom5csx-dart-evdk/tree/master/fpga
You want the vdk_single if you are using just one camera interface.
The board_spec.xml is part of an OpenCL BSP,... Michael Williamson

I was looking for the one that is for the current VDK, so it would just have the ARM code.
I do have the code from the VDK files on the wiki. There isn't a 'BSP' there, but there are several versions of the FPGA code.
I guess I was loo... Ed Henderson

Hi Ed,
If you are looking for an FPGA project / BSP with VDK + OpenCL architected, I don't have one handy. I only have the reference FPGA project that works with the example ARM programs.
If you need that FPGA project, it should b... Michael Williamson

Mike -- I have several examples of Cyclone V BSP's that incorporate an OpenCL kernel. It would be *VERY* helpful to have a starting "BSP" for the VDK, because then I can use the other examples as a reference and add the OpenCL kernel int... Ed Henderson

Hey Mike, i've been reading manuals for the past few days, and learned quite a lot.
I see now how the BSP and Kernel fit together -- the BSP can contain a partition where the OpenCL Kernel is inserted.
The BSP can contain all of the co... Ed Henderson

DV 06:47 PM Software Development: RE: Rocko, possible memory leak?

VJ,
I agree after looking at your data and with the knowledge that I've run 5CSX SOMs for weeks plugged into the network without having them dead locking.
It looks like the kernel uses a fair amount of memory for ethernet, though i... Daniel Vincelette

VJ 03:25 PM Software Development: RE: Rocko, possible memory leak?

Dan, based upon the measurements I have done and input from Mike I think I have to write this off as normal behavior.
I have done some stress test where I stream data over Ethernet and the memory use does not increase uncontrolled.

Hello Dan/VJ,
Have you guys seen this stack overflow post about tracking socket buffers /
memory moving through the network stacks?

VJ 10:56 AM Software Development: RE: Rocko, possible memory leak?

Hi Dan.
I have monitored the memory use over the weekend. See attached plot where "free" is logged every 10 minutes.
Test steps:
1: Booting the board. Ethernet cables are connected to Eth0 and Eth1, but no dedicated traffic or connec... V J

I found an interesting reference to a presentation here:

It shows using both together, even multiple kernels. Unfort... Ed Henderson

MW 07:51 PM MitySOM-5CSX Embedded Vision Developer's Kit for Basler dart BCON Support: RE: Intel OpenVINO with the VDK

You can, but you have to implement all of that stuff as part of the "BSP" if you don't want to implement it all in OpenCL (which, for the RAW LVDS inputs, is not possible I don't think).
I have only played around a little with that, a... Michael Williamson

EH 06:04 PM MitySOM-5CSX Embedded Vision Developer's Kit for Basler dart BCON Support: RE: Intel OpenVINO with the VDK

There is one key part that I'm not able to wrap my head around just yet. If you have some knowledge here, it would help greatly.
What I know is that I can write an OpenCL kernel that performs some work. I can write a host program with... Ed Henderson

VJ 03:54 PM Software Development: RE: Rocko, possible memory leak?

Hi Dan
Yes, 2 and 3b are the same.
I have done some more monitoring where Eth0 is connected but not used and Eth1 is pinged every sec.
Next eth0 and eth1 are taken down after 11h 30m: V J

DV 01:42 PM Software Development: RE: Rocko, possible memory leak?

Hi VJ
Those are definitely interesting findings leads me to believe like yourself some part of the ethernet subsystem is causing it. Would you say your test for 3b and 2 are the same? If not what are the differences?
I switched to ... Daniel Vincelette
