Vitis Vision Library 2021.2- colorcorrectionmatrix not working

[kapoor7997]

Hi vt-lib-support,

Linking it to this issue(#80) as the 2020.2 is also failing.

I have been working on getting the Vitis Vision Library 2021.2 working to show a demo to our clients(OUR COMPANY's WHOLE FUNDING IS BASED ON THIS WORKING).

My setup:
Board: ZCU102
Vivado: 2021.2
Vitis: 2021.2
Petalinux: 2021.2

Step I did:

1. I cloned the Master branch on Vitis_Libraries(https://github.com/Xilinx/Vitis_Libraries)
2. I followed the Vision README
3. I DONT have an ALveo card. I want to build for Embedded Platform(ZCU102)
4. Downloaded ZCU102 Base 2021.2 base image and ZYNQMP common image for 2021.1 from here(https://www.xilinx.com/support/download/index.html/content/xilinx/en/downloadNav/embedded-platforms.html)
5. I created a sysroot from the ZYNQMP common image for 2021.1
6. I want to build for ZCU102 so was working with L2/examples/colorcorrection/matrix and followed this README(https://github.com/Xilinx/Vitis_Libraries/blob/master/vision/L2/README.md)
7. I used following commands for compiling

• source /tools/Xilinx/Vitis/2021.2/settings64.sh
• export DEVICE=/home/dev64/Downloads/ThisPc_Petali/xilinx_zcu102_base_202120_1/xilinx_zcu102_base_202120_1.xpfm
• export SYSROOT=/home/dev64/Downloads/ThisPc_Petali/xilinx-zynqmp-common-v2021.2/sysroots/sysroots/cortexa72-cortexa53-xilinx-linux/
• export EDGE_COMMON_SW=/home/dev64/Downloads/ThisPc_Petali/xilinx-zynqmp-common-v2021.2/
• export PERL=/usr/bin/perl
• make host xclbin TARGET=hw HOST_ARCH=aarch64

8. This generated the sd_card folder in the package_hw folder.
9. To prepare my board, I made two partitions in the my board's SD card- 1.boot and 2.root. I copied the contents of sd_card folder into the boot partition of the Board's Sd Card. I extracted the rootfs.tar.gz from the common Image into the root partition of the SD card
10. I booted this and I was seeing the console ERROR shown in the PIC(libvideoioError.png). I could not see the libopencv libraries in the running linux on board. PIC(2_noOpencvLibraries.png). I found that the /usr/lib of running linux did not have the libopencv libraries. The libraries exist into the root partition /usr/lib but not in the running linux.
11. If you notice carefully, I built it on 2021.2 but it still shows 2020.2 on the command line.
12. Then I found that sd_card folder did not have the system.dtb.
    13.I copied the system.dtb from the base image to the board's SD card's boot partition. Booted again.
13. Now I could see the libraries in the running linux. Also now I could see the board was showing that it was running on 2021 petalinux. (Pic 3_2021petalinuxNowShowing.png)
14. Then I exported the XCl_BINDIR on the board.
    export XCL_BINDIR=/mnt/sd-mmcblk0p1/
15. Then ran the script and I got this (Pic Attached 4_finalHangingError.png):

root@zynqmp-common-2021_2:/media/sd-mmcblk0p1# export XCL_BINDIR=/mnt/sd-mmcblk0p1/
root@zynqmp-common-2021_2:/media/sd-mmcblk0p1#
root@zynqmp-common-2021_2:/media/sd-mmcblk0p1#
root@zynqmp-common-2021_2:/media/sd-mmcblk0p1# sh run_script.sh
INFO: Running OpenCL section.
Found Platform
Platform Name: Xilinx
INFO: Device found - edge
XCLBIN File Name: krnl_ccm
INFO: Importing ./krnl_ccm.xclbin
Loading: './krnl_ccm.xclbin'

18. It goes up to the point of Loading the xclbin kernel and then hangs up.

I have been working on vitis vision libraries for a while just trying to get them working and I had a errors in the 2020.2 environment (#80 )and after I confirmed that Xilinx's own common image and base embedded platform of 2020.2 is failing to run successfully I have not received any comment from Xilinx after that.

Now I have confirmed that Xilinx's 2021.2 vitis libraries are also hanging.

I need help with this as OUR FUNDING IS 100% DEPENDENT ON THIS DEMO.

Thanks,

I saw that there was an error but the sd_card folder still got created. We already know from my previous comment that it didnt have system.dtb in the sd_card folder.

Please look at the file, ConsoleHostSide_LD_ibrary.txt

Console had this error:
"LD_LIBRARY_PATH=:/home/dev64/Downloads/ThisPc_petali/visionlibrary2021.2_project/xilinx-zynqmp-common-v2021.2/sysroots/cortexa72-cortexa53-xilinx-linux//usr/lib :/lib
/bin/sh: :/lib: No such file or directory"

NOW:
Attached is the console output of the board. Filename is: boarSide_run_Script_dmesg_intterrupts.txt
Look for following tags in the file:
D-MESSEGE
ZOCL_Intterrupts1
ZOCL_Intterrupts2
run_Scipt_Hangs

Looks like zocl interrupt is never coming.

Hi @kapoor7997 ,

In the environment setup, the SYSROOT should point to aarch64-xilinx-linux instead of cortexa72.....
However, this looks like some issue with the hardware setup and not with the library code. (Please run software emulation and hardware emulation to confirm on your end too)

We suggest you to create a ticket in the forum where you can get the technical assistance to debug your stall issue on the board. This page has the info on the process.
