Just received a couple of these today, the wrover version with 2 MB PSRAM. Any advice on what I can try to compile micropython to this single core esp32?

This PR adds a new esp32 port board definition GENERIC_S2_SAOLA.

Changes made in this commit follow @dpgeorge's advice on #6925 (https://github.com/micropython/micropython/pull/6925#issuecomment-782547267)

So far, I have successfully buit, flashed, and reached REPL on IDF versions:

v4.3-beta2
v4.3-beta3

Closes #7299

Assessment

S Sonnet · medium

Issue #5958 asks how to compile MicroPython for the ESP32-S2-Saola-1 board. PR #7300 adds an official board definition (GENERIC_S2_SAOLA / ESP32_S2_SAOLA) for exactly that hardware, which directly answers the user's question. However, the PR explicitly closes #7299, not #5958, and the original issue is a support question rather than a formal feature request — it may have already been answered in comments. The PSRAM aspect from the issue is also not explicitly addressed in the PR diff.

Suggested action

If PR #7300 was merged, close issue #5958 as resolved — the board definition it adds directly enables building MicroPython for the ESP32-S2-Saola-1. Reference the PR in the closure comment. If the issue already has a comment resolving it, close as answered.
