I am getting region 'RAM' overflowed errors when building a Zephyr project using lvgl 8.3 using nRF Connect for VS Code add-in. I see a lot of references to lvgl when building, such as:
[352/429] Building C object modules/lvgl/CMakeFiles/..__modules__lib__gui__lvgl__zephyr.dir/opt/nordic/ncs/v2.3.0/modules/lib/gui/lvgl/src/extra/widgets/calendar/lv_calendar.c.obj
Even when I added this to the prj.conf it still shows up in the terminal:
CONFIG_LV_USE_CALENDAR=n
There does not seem to be much documentation on Zephyr and lvgl, but the prj.conf appears to have some settings which I assume are to control which components are used. When I changed the default font in it, the font changed on my screen.
CONFIG_LV_FONT_DEFAULT_MONTSERRAT_28=y
Here are all of my configuration settings:
