Linux/AM5728: detect_barcode with live camera with PSDK 3.2.0.5

Part Number: AM5728

Tool/software: Linux

Hi,

using Processor SDK 3.2.0.5

root@am57xx-evm:/usr/share/ti/image# detect_barcode sample_barcode.jpg 1 1

with the sample_barcode.jpg works.

Now I wanted to test the live camera (here on an AM5728 IDK) with the camera board connected. The camera is on

/dev/video1

The camera btw works with the dual_camera demo. The AM5728 IDK has only one camera connected.

So I am trying to run

root@am57xx-evm:/usr/share/ti/image# detect_barcode 1 1 1
Frame per seconds : 30
init done
Using Wayland-EGL
wlpvr: PVR Services Initialised
Segmentation fault (core dumped)

Can we fix this?

Thanks,

Hi Gunter,

According to Processor SDK barcode reader tutorial:
processors.wiki.ti.com/.../Processor_SDK_Barcode_Reader
Before running the detect_barcode scripts, you must ensure that matrxi GUI has been stopped and weston is up running.
If it is done but the issue still appear you can barcode_zbar command as it is described. Also check the detect_barcode script behaviour with the previous PSDK version.
There is an other useful barcode reader description at:
processors.wiki.ti.com/.../Barcode_and_QR_Code_with_Beaglebone

Hi Tsvetolin,

I just retested on an AM5728 EVM. Here were my steps
[] bootup then /etc/init.d/matrix-gui-2.0 stop
[] run
root@am57xx-evm:/usr/share/ti/image# detect_barcode 1 1 1
Frame per seconds : 30
init done
Using Wayland-EGL
wlpvr: PVR Services Initialised
Segmentation fault (core dumped)

I found that with a fresh generated SDCARD the detect_barcode 1 1 1 was actually running for about 1 minute until it got a segmentation. fault. But now even after a reboot, I am getting a segmentation fault right away.

We should check into it.

Regards,

Hi,

this may have fallen through. Do you have an update on the segmentation faults when running the detect_barcode 1 1 1, i.e. with a live camera source.

Have we done more testing?

Thanks,
