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?

bug

Hello,

when i want to flash my EP32 S2 WROOM with:
ESP32_GENERIC_S2 Firmware,
for this board: https://www.ebay.de/itm/402729974993
ESP32-S2-WOOR V1.1 WIFI Wireless Module Type-C Development Board ESP32-S2

then i get this error:

MicroPython v1.21.0 on 2023-10-06; Generic ESP32S2 module with ESP32S2
Type "help()" for more information.
>>> ESP-ROM:esp32s2-rc4-20191025

With this firmware is everything fine: ESP32_S2_WROVER-20220618-v1.19.1.bin
but i not found the v1.21 from it ... i only found is discussion here in github, that i have to use the generic (but there is this error above)

Assessment

Q Qwen · high

Both issues concern ESP32-S2 boards with PSRAM support in MicroPython. Issue #5958 is a question about compiling for the ESP32-S2-Saola-1 board with 2MB PSRAM. Issue #12826 is a bug report about PSRAM initialization failures on a different ESP32-S2 board (ESP32-S2-WROOM) with the generic firmware. While they share the same component (esp32) and concept (ESP32-S2 + PSRAM), they address different specific problems: one is a compilation/build question for a specific board, the other is a runtime PSRAM initialization bug. The candidate does not resolve the query's request for guidance on compiling for the Saola-1 board.

Suggested action

Keep both issues open. The PSRAM initialization bug in #12826 may inform future board support improvements, but it doesn't directly answer the compilation question in #5958. Consider adding a comment to #5958 linking to #12826 as related context about PSRAM issues on ESP32-S2 boards.
