How to show console in display(HDMI display)

I'm struggling to find that how to show console in display(HDMI display)
My goal is show Linux KMS framebuffer console on HDMI/DP: kernel/boot logs on screen and a tty1 login prompt (no Weston/X).

I could use it through serial, but not yet display with keyboard

I tried demo-image-base but it show black screen on display.(removed x and wayland from image recipe)
And I edited /boot/extlinux/extlinux.conf like below, but still not work.

APPEND ${cbootargs} console=tty0 loglevel=7 plymouth.enable=0
console=ttyTCU0,115200 firmware_class.path=/etc/firmware
(Removed: quiet, splash, video=efifb:off)

And tried set getty

systemctl set-default multi-user.target
systemctl` enable --now [email protected]

Can anyone point me to show console in display?

Hi, @yangwoolee, you working with Meta Tegra Yocto BSP, right? If so:

1. What release?
2. Do you see the console coming up during early boot or not at all?
3. What is this output: sudo dmesg | grep -i console?
4. Does the framebuffer device exist? Can you check which driver creates it with: udevadm info -a -n /dev/fb0 | grep DRIVERS?
