Hi @kevin.tx , thanks for answeing.
I guess my .ppm was created in the right way (i can easy use it in 4.x kernel).
Maybe the problem is that I didn’t disabled framebuffer console yet.
I’m having some trouble with this, I tried to do it from kernel configuration but because of some dependencies I can’t disable it.
I tried the instruction in the gui but I still have some print on the LVSD during the kernel loading/launching.
It print something like
[0.711577] imx-audmix imx-audmix.0: failed to find SAI platform device
Obviously I need theese message, but only the debug console, not on the LVDS.
On the old system my collegue did it but I can’t understand how i achived this
Hi @s.steiger ,
I tried to disable quiet option from u-boot env vars but the problem is still present.
The display “works well” since I can see the boot log on the display (the same I see on the debug console).
I tried to replace the .ppm image with a new one, I compiled the kernel again, but it doesn’t appear.
Is there something like an “image error” I can search in boot log?
Hi @henrique.tx ,
very thanks for your answer.
Enrico was a collegue of mine and he started this project on BSP 4.0.
I applied (after reviewing them) his patches to the meta and I reached good result.
Now I have a working system, I also removed framebuffer console from the display and everything seems to work correctly… except from the logo
I know it might sound silly but I have no idea why the splash image doesn’t appear.
I have already created kernel splash images for other systems without any problem, I guess I’m doing something wrong.
Splash screen is the only thing I need to do before starting the optimization of the system.
Hi @saijanani.tx ,
I confirm all points and I add this consideration:
I applied the patch from s.steiger and I also added some print to see if the patch was apllied correctly.
I disabled frambuffer console, infact my setupargs is : vt.global_cursor_default=0 consoleblank=0 quiet console=ttyLP1 earlycon
The very first time I used a 1920x1080 image, since in BSP 4 I used that image and everything worked.
After reading the article I tried also with smaller images: 1000x1000 for example and now I’m doing with a 1891x1051 image.
I did the steps described in your gui to get this image.
I’m sure there is something silly I am ignoring because everything seems correct.
If it can be usefull, here you can download my splash image.
I also want to say that display seems to be set correctly also in the Kernel, infact If I don’t disable framebuffer console I see all messages on the display, so it seems to work.
I tried with your image and it doesn’t work for me either. So, I believe there is something wrong with how the image has been created. Could you maybe try to make the image again, according to the article here.
I would also check if the splash screen works, by trying with the default logo_linux_clut224.ppm. When this works, you can confirm that there is nothing wrong with your frame buffer or so. This helps to narrow down the source of the issue.
