ESP32-S3 WROOM-1u N16R8 - enabling PSRAM

Dear all,

I am using the ESP32-S3 WROOM-1U N16R8, the ESP-IDF 5.3.1 and Visual Studio Code.
I want to enable the 8 MB PSRAM. Looking into the documentation the enabling should be possible by:
1. idf.py menuconfig
2. click on Component config
3. click on Hardware settings
Then it should be possible to select "SPI RAM config", but that option is not available in my case. I get a menu having the options: Chip revision, MAC Config, Sleep Config, RTC Clock Config, Peripheral Control, GDMA Configurations and Main XTAL Config. I have tried them all, but none lead to enabling the PSRAM.

Please, how do I enable the 8 MB PSRAM?

Regards,
Jorgen

Dear all,

Problem solved.

Within the Component Config menu there is an item named ESP PSRAM giving access to the enabling and configuration of the PSRAM. (The Espressif documentation needs an update)

Thanks,

This link provides better information, but as stated in my previous mail the way is wrong on how to get to the parameters configuring the PSRAM.
