Hi ESP32 team!
does the esp32-Pico-d4 can support external psram ?
the IDF seems can not work with psram for this chip, but the chip datasheet gives the referer psram schamatic connection.
please help comforme this .
thank you!

ESP32-PICO-D4 外接PSRAM 问题。
请问ESP32-PICO-D4 可以外接PSRAM 吗？如果可以能内部的FLASH和外部的PSRAM可以同时工作吗？
我看芯片规格书是可以外接PSRAM的，并且有给出电路图，但是IDF 好像不支持。
//psram gpio init , different working frequency we have different solutions
esp_err_t IRAM_ATTR psram_enable(psram_cache_mode_t mode, psram_vaddr_mode_t vaddrmode) //psram init
