imx6 booting into Qt application with no logo, desktop showing etc

Hi All,

Our customer requires our imx6 sabre dual-lite solution to boot straight into the qt5 application without seeing any of the intermediate screens while booting, e.g no Yocto logo ( turned this off in menu-config ), no boot progress bar, no match-box desktop. So in a nut shell, turn the power on -> Qt5 app runnning, that's all the end user would see.

What would be steps required to do this? Also where would be the most appropriate place to start the Qt aplication from?

Thanks,

Ed.

Hi Edward,

You can disable the kernel logo from Linux -fsl def config as: -CONFIG_LOGO=N

For the yocto splash screen you can change the PSPLASH_BACKGROUND_COLOR in psplash-color.h

Hope this helps

Hi Analogics Tech India Limited,

For changing the boot logo .. you have to do the below following the steps,

1) convert any type of image  yourlogoname.(jpg.bmp,..etc)  to  yourlogomname. png  format

2) convert yourlogomname.png to yourlogomname.pnm 

3) convert yourlogomname.pnm to yourlogomname.ppm

4) replace the  default.ppm to yourlogomname.ppm (i e. in .../ driver/video/logo/yourlogomname.ppm)

5) Recompile your image i.e zImage or uImage Thats it,

Hi,

The project got passed on around that stage but the next Engineer tells me that is was to do with the matchbox session manager.

In the user session script there's the ability to removed parts of matchbox starting up, header, tasktray etc. There's a logo option in the menuconfig too.

Hope this helps, as mentioned the project got passed on.

Have a look in your menuconfig and search for something like "logo" or "boot logo" or similar. It may be in Boot options-->

It's there somewhere as I've used it before.

From what I remember in my kernelconfig you could actually set the path for the icon ( if required ). If all else fails menuconfig should state the name of the icon and you might be able to do a system wide file search and replace it as a test - with same name obviously. Once located you can do it properly using the layer/recipe way.
