[Answered] ESP32-WROVER ... no access to the 4MB psRAM

Postby kolban » Thu Jun 08, 2017 5:23 pm

I have just received the new ESP32-WROVER devKit which includes the new ESP32-WROVER module. However, when I compile and flash a new application (built with the very latest ESP-IDF), I don't see the extra memory. Just the memory on the ESP32 itself.

I have enabled boot logging and captured a trace. I have pasted that trace to the Internet here:

Hopefully I have made some newbie error with this new board. Does anyone else have an ESP32-WROVER? Did you immediately see the extra RAM or did you have to make some environmental changes?

You have to use feature/psram_malloc esp-idf branch and compile the toolchain...

...As well as enable the external RAM feature in menuconfig, it's not enabled by default.
