PSRAM issue of LOLIN S2 Mini

Using Arduino IDE 1.x
1

HI!

I'm using Wemos S2 mini board for my project and I select "LOLIN S2 Mini" on Arduino IDE.
Chipset number is ESP32-S2FN4R2 and it support 2MB PSRAM but I could not find any PSRAM enable menu.

If I get ESP.getHeapSize(), is show only 197,820 byte and ESP.getPsramSize() show 0 byte.

How can I use full 2MB RAM? Thanks a lot!

I found that ESP32-S2FH4(0 PSRAM) is mounted on board. I know that Wemos S2 mini must be mount ESP32-S2FN4R2, so this is almost fake..
