- 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,... - EH 12:00 AM MitySOM-5CSX Embedded Vision Developer's Kit for Basler dart BCON Support: RE: Intel OpenVINO with the VDK
- 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...

- 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... - EH 11:25 PM MitySOM-5CSX Embedded Vision Developer's Kit for Basler dart BCON Support: RE: Intel OpenVINO with the VDK
- 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...

- 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... - 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... - 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?

- 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...

- I found an interesting reference to a presentation here:

It shows using both together, even multiple kernels. Unfort... - 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... - 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... - 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: - 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 ...

- I was just looking through the code on that. I've already cloned the git repo.
I'll use that as a starting point. It won't have any of the code related to the VDK, i.e. the Basler LVDS input logic, and the image processing flow that ... - MW 04:27 PM MitySOM-5CSX Embedded Vision Developer's Kit for Basler dart BCON Support: RE: Intel OpenVINO with the VDK
- Hi Ed:
Have you looked at our OpenCL BSP reference kit for our MitySOM-5CSX DevKit?

It's a little old, but you could probably adapt/use... - EH 04:20 PM MitySOM-5CSX Embedded Vision Developer's Kit for Basler dart BCON Support: RE: Intel OpenVINO with the VDK
- Michael -- I am currently pursuing the OpenCL approach. It seems the most viable.
We are looking at OpenCL implementations of darknet, so my goal will be to see if/how much of a darknet implementation I could get working on the Cyclon...
