i.MX 6ULL - Is Qt5 Supported?

[brianptl]

Hi All,

I am following the document "i.MX Yocto Project User's Guide.pdf".

I have set up the development environment, e.g.

$ mkdir imx-yocto-bsp

$ cd imx-yocto-bsp

$ repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-rocko -

m imx-4.9.88-2.0.0_ga.xml

$ repo sync

etc..

Once I have done this, I see a note in the document ~/imx-yocto-bsp/README-IMXBSP

Note Qt is not supported on i.MX 6UltraLite and i.MX 7Dual. It works on X11 backend only but is not a supported feature.

My questions are:

• Does this note apply to the i.MX 6ULL? I think not from the wording, but I believe the 6ULL is based on the 6UL so I want to check.
• Is there a matrix of supported software vs i.MX 6 variant that I can refer to in order to determine we are picking the correct chip for our software requirements?

Thanks,

Brian.

Hi Brian,

We have ported QT5.6.2 on our MYD-Y6ULX board, but imx6UL can not support GPU and hardware graphics.

It can only display from software but video effects might not too strong.

And how to build yocto for imx6ull with qt5 and cross-compile qt application for it(or maybe better to compile it on the board)?

Hi Brian

i.MX6ULL is reduced version of i.MX6UL and it is also not supported,

as described in sect.2.1 New features attached Release Notes:

Qt 5 is not supported for SoCs without hardware graphics. Qt 5 video is not supported on SoCs without a VPU.
