uPython and Espressif DevKitC boards

Post by AwesomeCronk » Wed Nov 20, 2019 12:32 am

Does uPython work on the official Espressif DevKitC?
If so, which version of the firmware do I need?

The DevKitC is a host board that can contain many different modules. I have a DevKitC with a ESP32-WROVER-B module for example, which runs the GENERIC-SPIRAM firmware.

You can read the description of the modules at https://docs.espressif.com/projects/esp ... l#overview
Most of the PSRAM (or SPIRAM) modules will run GENERIC-SPIRAM, everything else should run GENERIC.

The exception is the SOLO which is not yet supported, see https://github.com/micropython/micropython/issues/5336

So, I am looking at purchasing the WROOM-32 version, as I believe that is the one listed on Mouser. Does uPython GENERIC or GENERIC-SPIRAM work on the special order 16MB flash version of the 32U/32D?

Following that, if the special order versions do work, how do I get a DevKitC V4 WROOM-32D with 16MB flash?

If the module has SPIRAM (also known as PSRAM), use the GENERIC_SPIRAM. Otherwise, use GENERIC.

The linked page points to https://docs.espressif.com/projects/esp ... er-modules which shows which modules have SPIRAM.
