Toradex Apalis imx6 quiet boot issue

Hello,

I’m having troubles trying to get my application with a quiet boot. All I want is to have a blank screen during the startup until my Application shows up.

I know that you can fix it by messing with the image’s source code, but I have no access to it, so there is a couple things i have already try:

  • Disabling framebuffer(s) (Vidargs).
  • Disabling console(s) (setup)
  • Changing the printk function so it doesn’t print message unless they are emergency ones (But I don’know if Idid it right)
  • Changing the stdoutoutput (Bootcmd)
  • Removing the echo function so it does nothing

Pastebin of my U-Boot enviroment

What exact hardware and software versions of things are you talking about?
