Lvgl on Portenta example

[dave85]

Hi Everyone. I'm trying to run the lvgl example from the Arduino website, but I'm getting the following compilation errors.

Arduino: 1.8.13 (Windows 10), TD: 1.53, Board: "Arduino Portenta H7 (M7 core)"

Error compiling for board Arduino Portenta H7 (M7 core).

I've tried the depreciated Portenta core, and lvgl v7.3.0 (as in the tutorial), but same errors. Does anyone know if I'm doing something obviously wrong before I start digging around in the lvgl source files? Thank you
