Tried everything - your code directly, your instructions cloning lvgl examples. Everything compiles fine flashes fine. Even used esp-idf-4.2.2 as well as the latest as of today. Tried multiple sc01's. I work in a Debian environment. The board is marked v3.2. checked all the menuconfig settings and compared to your file. Tried different projects. Same result just a bright white screen.

To add I did use the monitor and found several errors regarding the FT6X36 such as error reading from device. More specifically "Device reports readiness to read but returned no data. Device disconnected or multiple devices on port?"
