ESP32 Forum

is the chip "esp32-u4wdh" supports external psram? if yes can anyone please suggest the pin connections? i have made a custom PCB and getting the error of PSRAM Not detected, however i am using arduino IDE and presently i have selected the board type as PICO-D4 , because its having the same internal flash pins as U4WDH , but pico-d4 datasheet contains information about how to use external RAM and this general datasheet of esp32 its not there how to use external ram and pins.

please help

I am facing the same issue.

I have verified my connections with Espressif's technical team, they said the connections were okay.
Please let me know if you find anything.
