Hi @mhepp!
I never tried adding a new font format, I only used lvgl fonts created with LittlevGL font converter.
Any reason you don’t want to use lvgl font system? They put a lot of work in it, it supports advanced features such as compression, kerning etc. and you can convert any TTF font to lvgl font using the font converter tool.
Regarding your crash, I suggest you try to debugging it. The backtrace you got is a good starting point:

What you need to do is:
- Make sure you build your project in DEBUG mode, with debug symbols
- Parse this line with addr2line
