General issue report

Hello,

Is there any documentation on the DDR/120MHz rate support of the in-package PSRAM of the ESP32-S3-MINI-1 modules (which according to the data sheet contained a ESP32-S3FH4R2)?

Thanks!

Hi @ProfFan ,
ESP32-S3FH4R2 is equipped with 4MB flash (FH4) and 2MB PSRAM (R2), both connected via QuadSPI. Quad PSRAM supports only STR mode, DDR won't work for you. See https://docs.espressif.com/projects/esp-idf/en/stable/esp32s3/api-guides/flash_psram_config.html for more details
