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

TIMEOUT 30
  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=18.1.2.0.0 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,

forever3000,

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.

Thanks and Best Regards,

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