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
