Part Number: TDA2PXEVM

Tool/software: Linux

Hello:

Background

We'are working on VisionSDK 3.05, for the QT environment we copy from PSDKLA 3.4.3 which the QT version is 5.6.

To support the full-screen and position control on QT application, we should select the ivi-shell in weston which require the QT version is newer than 5.7

we saw the PSDKLA 5.00 support the QT 5.9

PSDKLA 5.00

PSDKLA 3.04

Question

Can we directly copy the QT library from PSDLA 5.0 to VisionSDK 3.5
If not, how can we upgrade QT on visionsdk to 5.9.7?

Thanks.

Hi,

> for the QT environment we copy from PSDKLA 3.4.3 which the QT version is 5.6.

What file system are you using? PSDKLA 3.4.3 or something else. I am trying to understand why you have to copy the components.

On 1, Copying QT library might not necessarily work, some of its dependencies might have updgraded to newer versions as well.

On 2, You can try building the QT 5.9.7 from Yocto, it will take care of all the dependencies.

Thanks,
Gowtham

The VisionSDK rootfs contains parts of QT library which is also 5.6, and we copy others from PSDKLA then the QT environment on VisionSDK 3.05 is ok.

As the network limitation, we can not access the remote server, and we are working on the visionSDK, we don't know whether the yocto support the visionSDK.

and by the way, Can we use the toolchain in visionSDK to build QT standalone?

Hi Andy,

You can try building QT with linux-devkit.

Please refer to this thread.

TI has not tried building all QT applications with linux-devkit alone. I recommend yocto to build qT if this doesn't work.

I found these set of patches to enable ivi-shell on qt5.6. This may help you. Please try.

Hello RamPrasad:

before building QT from YOCTO, can you share us the organization of visionSDK

how the rootfs of visionSDK(software-dl.ti.com/.../tisdk-rootfs-image-dra7xx-evm_vsdk_3_7.tar.xz) come from? can it directly built by yocto project?
is any dependency between the rootfs and PROCESSOR_SDK_VISION(software-dl.ti.com/.../PROCESSOR_SDK_VISION_03_07_00_00_setuplinux.bin)
