I have an Adafruit Feather ESP32-2 TFT.

The MicroPython firmware download page has no exact match for this. How do you go about finding an existing firmware that will work? I don’t expect the display part to work. What aspects of a board do you have to consider to figure out which existing firmware will fit?
Is there a document somewhere that goes into this kind of thing?

ESP32-S2
If Adafruit can't tell you I'd try:
https://micropython.org/download/GENERIC_S2/
If that doesn't work I'll tell you how I would try to find out what actual chip variant they use.

Re: How To Pick Right Firmware To Download
I’m not an expert on this, but the Adafruit Feather ESP32-2 TFT has 4 MB flash + 2 MB of PSRAM. Does that imply that it is using SPIRAM? If so, then will the generic firmware handle that? I saw some firmware by Unexpected Maker for an ESP32-2 that mentioned SPIRAM, but then I haven’t any idea if that will work.
Re: How To Pick Right Firmware To Download
The GENERIC firmware will not use the PSRAM at all, but it should run. The S2 board from Unexpected Maker uses PSRAM, but has a larger RAM size, but the RAM size is not mentioned in the config files. It may work. Just try it.
