You mean the default_16MB.csv? That’s flash. It’s complaining about Data RAM not being enough. Does your board have PSRAM, like 4 or 8 MByte maybe?
You can easily get to that point if you misconfigure the buffer size for LVGL.
You can absolutely find out what is trying to take up so much RAM with the technique I showed in I would even be willing to bet it’s due to the same cause: Not configuring LV_MEM_SIZE properly.
