GUI for iMX 6UL with LCD

kanimozhi_t — Mon, 13 Jul 2020 11:24:03 GMT

Hi,

We're currently working in enabling GUI on iMX 6UL, with NXP's LCD8000-43T LCD module. We've built a Sato image in Yocto warrior and ran it on the board.

On the initial run of Sato image, we found the touch calibration is unreliable and the overall experience to be choppy. The touch is unresponsive and the scrolling take minutes. So it's kind of failure and we had to move on.

We further found that QT5 is not supported on the iMX6UL as it lacks the GPU and wonder what's the way for GUI on iMX6UL??

SUMMARY OF QUESTIONS:

1. Is there a way to optimize Sato image for iMX6UL?

2. What's the best way to have a GUI on iMX6UL?

Thanks in advance.

Hello Kanimozhi,

You can use QT5 with the i.MX6UL but without QML. The QML requires the Qt Quick 2D

raster library to work without 3D GPU and this is a commercial module from The Qt Company.

Thanks for the update.

Can you give me more details about how can we build 'fsl-image-qt5' without QML?

Thanks in advance.
