Hello,
I checked in mentioned article but it is for colibri T20. Setenv command is for colibri but I tried same command for apalis imx8 and getting same issue.

**Apalis iMX8 # setenv setup 'setenv setupargs asix_mac=${ethaddr} no_console_suspend=1 vt.global_cursor_default=0 console=ttyLP1,${baudrate}n8 **
debug_uartport=lsport,0 ${memargs}’
**Apalis iMX8 # **
**Apalis iMX8 # **
**Apalis iMX8 # printenv setup **
setup=setenv setupargs asix_mac=${ethaddr} no_console_suspend=1 vt.global_cursor_default=0 console=ttyLP1,${baudrate}n8 debug_uartport=lsport,
0 ${memargs}
**Apalis iMX8 # saveenv **
Saving Environment to MMC… Writing to MMC(0)… OK

Can you please share me process and command for apalis imx8 for splash screen ASAP?

Hi @dipakshetye,

You need to follow steps mentioned in kernel splash screen article to enable splash screen.

Once you get splash screen then set below kernel cmd line parameter to disable kernel messages

Apalis iMX8 # printenv setupargs 
setupargs=vt.global_cursor_default=0 consoleblank=0 quiet console=null earlycon

Hi @ritesh.tx ,
We followed steps mentioned here High performance, low power Embedded Computing Systems | Toradex Developer Center and set the u-boot environment variable setupargs as per your input.

Apalis iMX8 # printenv setupargs 
setupargs=vt.global_cursor_default=0 consoleblank=0 quiet console=null earlycon

But we could not see splash screen on the HDMI.
Could you please share your thoughts?
In addition to this we added a package ‘pslash’. With this package we can see the boot logo for an instance but it disappears immediately and wayland application starts running. Could you please share your input on this?

Hi @prathamesh.kulkarni,

Can you please share video to further check and understand about issue. If possible kindly share video to support.in@toradex.com.
You can use our sharing platform share.toradex.com

Please also note with HDMI splash screen comes once display handshake is done which can take some time compared to other display like lvds or parallel rgb etc.

Hi @prathamesh.kulkarni ,

Seems like your splash screen working good. With HDMI and Apalis iMX8 spalsh screen only comes once display init done. Here also splash screen comes but soon after this weston starts.

With TorizonCore we have used Plymouth splash screen running in userspace. Please check below link
One option you can check

Hello @ritesh.tx ,

Thanks for your inputs.
We do not have TorizonCore setup. We need to use the splash screen in toradex reference multimedia image using Yocto Project. Is there any way to see splash screen for some more time?
