What is the ESP31?

[wrbuckley]

In the file FreeRTOSConfig.h, there appears this comment, near the close of the FreeRTOS V8.2.0 rights statement:

/* ESP31 and ESP32 are dualcore processors. */

So the question is, what is an ESP31?

Alternatively, is the reference to ESP31 simply in error?

Thanks.

The ESP31 was the beta silicon (think 'engineering sample') for the ESP32. It's not produced or supported anymore and is more of a historical artifact by now. The remark probably is there because the ESP31 was the processor that we originally developed the first version of our multicore variant of FreeRTOS on.
