meta-udoo rocko for UDOO Neo

invalid@example.com (cyrilf) — Fri, 21 Jun 2019 18:05:20 +0000

Hi,

I updated my repo to the rocko branch. I only support UDOO Neo because I don't have the other boards.

It uses a backport recipe for U-Boot FSLC 2016.11.
An other backport recipe provides the last version of the WL18xx driver that fixes major issues with the Wi-Fi.
It provides Qt 5.9.x

hello all, I am very new as yocto user. I have an udoo neo board and I would like to change hostname in yocto config. I followed some methods found on the internet, such as changing local.conf with different keywords but none of them worked.
Please can you suggest me some methods to change hostname in yocto build ?
Thank you very much

Qt release build Yocto SDK

invalid@example.com (Retasor) — Fri, 07 Dec 2018 10:50:14 +0000

Hello,
I have build yocto with qt for the Seco-SA62
everythings works fine and I can build my Qt applications although when I try to build a release build instead of a debug build. It continues to build a debug build.
I think its something in the Qt-yocto build but I can't figure out where I need to search to solve this.

video flickering during play with qmlvideo example on eglfs

invalid@example.com (Mauro) — Fri, 20 Jul 2018 12:19:32 +0000

Hi,

I already posted this problem in QT forums and mailing list but without a response, so I'm trying here. I googled a lot for a solution, but I haven't found anything.

I'm developing an embedded board based on iMX6SX SOC (the same of Udoo NEO); due to some issues on video reproduction, I switched to a Udoo NEO board to do some tests, and also here I'm facing the same issues. So I decided to write here to warn this community about this behavior (and to try to solve it).

On this board I...

How to enable OpenVG support with meta-qt5?

invalid@example.com (cyrilf) — Mon, 16 Jul 2018 06:53:34 +0000

Hi,

Have you ever enabled a third party library support for meta-qt5? I'd like to enable OpenVG to be able to display SVG elements with a reasonable CPU usage. Now it uses more than 70% of the CPU to display 3 simple SVG files on a 7'' screen.

I've added this line to my configuration file:

Code:

PACKAGECONFIG_append_pn-qtbase = " openvg"

but nothing happened. I wonder if I forgot to set a QT_* env variable or something?

I have build an Yocto image for the SECOSBC-A62 with Qt support. I build the image following @graugans instructions built used the latest version of the meta-qt.

When I try to use this in my package it is complaining that Qt Quick Extras is missing. It seems part of the qtquickcontrols and that one I have...

Hi all,

I am having trouble getting a SSH connection via USB to my Udoo Neo running Yocto.

Using udoobuntu I can get it to work, but it seems on Yocto, the USB is not properly started.

Anyone here that can point me in the right direction? Thanks in advance.

Yocto Qt and Fonts

I have build an Yocto image according to @graugans instructions and Qt support.
All ok and working. Only the Fonts in the Qt application are doing strange things.
When starting the Qt application it tells me a Helvetica font is loaded and used. But for as far as I know Helvetica is a Sans-Serif type while all letters are in the Serif type. When I overload the default font setting by

Yocto + Qt5 + LVDS on i.MX6 (FSL Community BSP): Rendering and color depth

invalid@example.com (juliend) — Sat, 21 Jan 2017 10:42:17 +0000

I've made my own yocto image for a Udoo neo board using graugans/meta-udoo, in eglfs mode (no X11 / Wayland), following this tutorial : http://wiki.wandboard.org/index.php/Building_Qt5_using_yocto_on_Wandboard
Then I developped a simple QT5 application displayed on Udoo's 7" LVDS display.
The rendering of my image is not correct. It seems to be displayed in R/G/B/A = 4/4/4/0 instead of 6/6/6/0.
How can I specify this values before launchning my application ?
Moreover, transparency...
