Disable boot log and display splash screen with 28.1 version

Dear all,

I want to disable the boot log and display splash screen while booting up but I didn’t know how to do it with 28.1 kernel version.

With 27.1 kernel version, it look like more simple by changing boot environment as below

  DEFAULT primary
  MENU TITLE p2771-0000 eMMC boot options
  LABEL primary
     MENU LABEL primary kernel
     LINUX /boot/Image
     FDT /boot/tegra186-quill-p3310-1000-c03-00-base.dtb
     APPEND <s>fbcon=map:0</s> net.ifnames=0 <s>console=tty0</s> OS=l4t console=ttyS0,115200n8 memtype=0 video=tegrafb no_console_suspend=1 earlycon=uart8250,mmio32,0x03100000 gpt tegraid= tegra_keep_boot_clocks maxcpus=6 android.kerneltype=normal androidboot.serialno=0335115020673 vpr_resize root=/dev/mmcblk0p1 rw rootwait

So with 28.1 version how can I handle this.

Thanks and Best Regards,

The splash screen is implemented in bootloader level in rel-28.2. We don’t support it in kernel level.

Thus, I would suggest to upgrade to rel-28.2. Also, the public cboot source is for rel-28.2.

Hi WayneWWW,

Is it possible to use bootloader rel-28.2 with kernel rel-28.1? Due to we have already ported many drivers to kernel rel-28.1, it will take time if move to kernel rel-28.2.

I’m afraid it is not possible since it took us months to fix all issues on rel-28.1 for splash screen.
