Linux for IMX8 : switch to virtual console

[tan-k]

Hi,

I need to switch to virtual console.
I try, but have an issue. Cannot switch to virtual console sometimes.
Could you please tell me this solution?
About details, please refer below.

[Environment]
Evaluation Kit : 8MMINILPD4-EVK (Connect HDMI cable, USB keyboard and USB mouse.)
Linux for i.MX : Linux 5.4.70_2.3.0​ (Download "L5.4.70-2.3.0_images_MX8MMEVK.zip" and flash "imx-image-full-imx8mmevk.wic" to SD card.)

[Procedure]
1.Trun on the power to evaluation kit. Then boot from SD card.
  ->Wayland Weston desktop is shown on the screen.
2.Press "Ctrl + Alt + Fn1(or Fn2-Fn6)" key to switch to virtual console.
  ->Virtual console screen is shown for a second, then Wayland Weston desktop is shown.
    Move the mouse, but the pointer on the screen does not move.
3. Press "Ctrl + Alt + Fn7" key to return Wayland Weston desktop.
  ->Move the mouse, the pointer on the screen moves normally.
4.Click weston-terminal icon on toolbar and execute weston-terminal. Input some keys on terminal.
  Then press "Ctrl + Alt + Fn1(or Fn2-Fn6)" key to switch to virtual console.
  ->Can switch to virtual console normally.
5. Press "Ctrl + Alt + Fn7" key to return Wayland Weston desktop.
  ->Wayland Weston desktop is shown.
6.Press "Ctrl + Alt + Fn1(or Fn2-Fn6)" key to switch to virtual console again.
  ->Same result as procedure 2. Then input some keys.
7. Press "Ctrl + Alt + Fn7" key to return Wayland Weston desktop.
  ->Move the mouse, the pointer on the screen moves normally.
8.Click weston-terminal icon on toolbar and execute weston-terminal. Input some keys on terminal.
  Then press "Ctrl + Alt + Fn1(or Fn2-Fn6)" key to switch to virtual console.
  ->Can switch to virtual console normally.
    And keys which I input at procedure 6 are shown virtual console screen.

I think there is issue when switch the screen.
Switching control works normally because we can input key.
Any help would be appreciated.

Thank you.

Best regards,
