SD WIFI PRO PSRAM not detected in ESP-IDF

[milindmovasha]

Hello, as per the description on the sales page link here:

https://www.fysetc.com/products/fysetc-upgrade-sd-wifi-pro-with-card-reader-module-run-wireless-by-esp32-chip-web-server-reader-uploader-3d-printer-parts?_pos=1&_sid=a6fdbeb30&_ss=r

the FYSETC Upgrade SD WIFI PRO card has 2MB PSRAM. However, if PSRAM is enabled on the same module in ESP-IDF v5.4 then I get the following error while booting:

I (582) quad_psram: This chip is ESP32-PICO
E (584) quad_psram: PSRAM ID read error: 0xffffffff, PSRAM chip not found or not supported
E cpu_start: Failed to init external RAM!

Two questions:

• Does this module has 2MB PSRAM as stated? This module has ESP32-PICO-D4 chip which does not have in-built PSRAM as per EspressIf documentation here (https://www.espressif.com/sites/default/files/documentation/esp32-pico_series_datasheet_en.pdf). I could not find external PSRAM in the schematic. So I am confused with the description on the sales page above. Please clarify if the module indeed has the PSRAM or not.
• If yes, please let me how to enable PSRAM in ESP-IDF?
