PSRAM is not working in ESP32S3

Postby shailesh.korat » Tue Nov 30, 2021 6:34 am

I am using ESP32-S3-WROOM-1-N8R8 module in our project. As per datasheet, this module have 8 MB of External Flash and 8 MB of external PSRAM.

Now, I want to access external PSRAM in my project so I am enabling external PSRAM support from menuconfig.

However, I am getting following compilation error.

Code: Select all

/esp-idf/components/spi_flash/cache_utils.c:852: undefined reference to `psram_support_wrap_size'


Can anyone have any idea how to resolve it.

I am using master branch of ESP-IDF.

Make sure your CONFIG_ESP32S3_INSTRUCTION_CACHE_WRAP and CONFIG_ESP32S3_DATA_CACHE_WRAP are not set, because it seems OPI didn't support the cache wrap feature till now.
