LVGL creashed in play active mode

How to
1

I’m encountering an error when attempting to run a simulation in Play Active Mode using SquareLine Studio. The LVGL Python server console shows the following error
squareline studio error

I’m not sure what’s causing this error or how to resolve it. Could someone please help me understand:

  1. What might be causing the ‘Command not send: PKT_IN_TYPE_MOUSE’ messages?
  2. What troubleshooting steps would you recommend to resolve this error?

Additional information:

  • SquareLine Studio version: 1.42
  • Operating System: Windows 10
  • Project details: Screens - 123, Widgets - 3285

I’d greatly appreciate any insights or suggestions on how to fix this issue and successfully run the simulation. Thank you in advance for your help!

Hi,

If “LVGL crashed” appears in the console, it means that LVGL received an instruction that it couldn’t execute. For example, if there’s a keyboard widget on one screen and a textarea on another, and the keyboard’s target is the textarea on the other screen, LVGL will crash because the textarea hasn’t been created yet when the keyboard is being created. The exact error is displayed in the console. “PKT_IN_TYPE_MOUSE” is written when you move the mouse over the screen that’s in a frozen state. Scroll up the console and you will see the error that caused LVGL to crash. After you’ve fixed the error that was displayed in the console, you can continue working by pressing the “restart LVGL” button.
