Unable to add SoftISP-based OpenVX samples in Yocto for IMX8

[lleoncr]

Hi everyone,

I have been looking for an option to enable SoftISP - OpenVX samples on an Nitrogen IMX8 mini. I have tried editing the recipe, but it seems to skip it. The edited recipe (https://github.com/Freescale/meta-freescale-distro/blob/master/recipes-graphics/imx-gpu-sdk/imx-gpu-sdk_5.0.2.bb) is below:

Did I forget something? How can I enable OpenVX?

Additional information:

I am using the following Yocto repo: https://boundarydevices.com/yocto-release-for-i-mx-8mm/ Board: i.MX8M MINI Target image: boundary-image-multimedia-full Compiling on Ubuntu 18.04

Thanks in advance, Leon.

Hey Leon,

As far as I've seen, SoftIP needs both OpenVX and OpenVX1.1 features to be enabled.

Extract from the build log show that: Could not build package 'OpenVX.SoftISP' due to missing features 'OpenVX1.1'

You'd need to add somthing like this to SDK recipe: FEATURES = "EGL,EarlyAccess,OpenVG,OpenVX,OpenVX1.1"

However, I guess it would not be recommended since OpenVX is not officially supported by this layer (otherwise it would be included here). The best course of action to be is to create a .bbappend in your BSP layer and append FEATURES variable there.

Thanks for the answer. I will take it into consideration and come back if it worked.

Hey Leon!

Thanks for the answer. I will take it into consideration and come back if it worked.

Did the above proposal worked for you? Is this issue still valid?

Hi Zandrey,

In the end, I could not integrate OpenVX with my platform. I was checking this page: https://developer.ridgerun.com/wiki/index.php?title=IMX8/SOC_Overview.

It says that my platform does not have support for OpenVX.

Thanks for your help and time.
