### LVGL doesn't start, randomly crashes or nothing is drawn on the display. What can be the problem?
- Try increasing `LV_MEM_SIZE`.
- Be sure `lv_disp_drv_t`, `lv_indev_drv_t` and `lv_fs_drv_t` are global or `static`.
- Be sure `lv_disp_t`, `lv_indev_t` and `lv_fs_drv_t` are global or `static`.
- Be sure your display works without LVGL. E.g. paint it to red on start up.
- Enable [Logging](porting/log)
- Enable asserts in `lv_conf.h` (`LV_USE_ASSERT_...`)

### How to reduce flash/ROM usage?
You can disable all the unused features (such as animations, file system, GPU etc.) and object types in *lv_conf.h*.
If you are using GCC/CLANG you can add `-fdata-sections -ffunction-sections` compiler flags and `--gc-sections` linker flag to remove unused functions and variables from the final binary. If possible, add the `-flto` compiler flag to enable link-time-optimisation together with `-Os` for GCC or `-Oz` for CLANG.
