PSRAM ID read error on ESP32-S3-DEVKITC-1-N8R8

[kneko715]

I build helloworld on ESP-IDF Eclipse and write it to ESP32-S3-DEVKITC-1-N8R8.
ESP-IDF branch is master. commit is 07bfc09d0c8837b4d149e1151c57635a0c02755a.
It works correctly.
After that, enable "Support for external, SPI-connected RAM" option on sdkconfig, build and write it to same board.
On boot, it shows following error message and repeat rebooting.

How can I enable PSRAM on ESP32-S3-DEVKITC-1-N8R8?

Thank you.

To setting the "Mode (QUAD / OCT) of SPI RAM chip in use" on sdkconfig to "Octal Mode PSRAM", PSRAM has worked correctly.

Thank you.
