[ESP32-S3] Using Octal PSRAM as QSPI PSRAM

[swoj_ic]

Is it possible to use an ESP32-S3 WROOM module (N8R8) which hosts an octal PSRAM module but use it instead as a QSPI PSRAM module? I recognize that total PSRAM would be reduced but want to find a firmware workaround to an issue.

No. Octal psram chips generally don't support a quad interface, and given the commands and addresses are also sent over those 8 wires, not using 4 of then is not going to work.
