See only 16MB Flash on 32MB ESP32­-S3­-DevKitC-1

Post by andyfruit »

Purchased from adafruit: ESP32­-S3­-DevKitC-1 - ESP32-S3-WROOM-2 - 32MB Flash 8MB PSRAM PID: 5364

It suppose to have 32MB of Flash.

spi_flash_get_chip_size()/(1024*1024 reports 16MB

Chip ID: 14750336

Any idea of what is going on.

Did I get a 16MB Flash instead of 32MB Flash ?

Is spi_flash_get_chip_size() reporting incorrectly ?


Thanks,
Andy

Andy,

It looks like an open issue to get full 32MB support, but you might be able to get further with the latest esp-idf release.

https://github.com/espressif/esp-idf/issues/8365

I assume you chip says ESP32-S3-WROOM-2 which is the tell that you have the 32MB chip.

My chip is labeled: ESP32-S3-WROOM-2 Good to know that is a 32MB version.

I will look into what is going on with support for the 32MB version.

Thank you.
