MicroPython on the ESP32-D2WD (2MiB)

port-esp32

In case anyone else is interested, I've managed to mod the source and a partitions.csv file to get MicroPython and its filesystem working on an ESP32-D2WD, which only as 2MiB of internal Flash, not 4MiB.

Modded ports/esp32/modules/flashbdev.py, ports/esp32/modesp.c, and ports/esp32/partitions.csv

I would recommend we not hard-code things to 0x200000 anymore, as Espressif offers 2MiB internal SPI flash chips. Perhaps we rework these changes a bit to make the built process account for flash user start addresses lower than 0x200000?

Assessment

S Sonnet · high

Both issues concern ESP32-D2WD partition configuration. Issue 5089 (query) explicitly references the screenshot from issue 4986 (candidate) as the working baseline before the regression. Issue 4986 is the prior work that enabled ESP32-D2WD support via manual partition/flashbdev modifications, while 5089 is a regression report claiming a subsequent patch broke that working setup. They share hardware (ESP32-D2WD), component (partitions.csv, flashbdev), and concepts (2MiB flash, partition layout), but 4986 does not resolve 5089 — it is the context preceding the reported breakage.

Suggested action

Link the two issues for context. Issue 4986 provides the original reproduction steps and configuration that 5089 refers to. Maintainer should investigate which patch introduced the regression for ESP32-D2WD and either update the partition handling for 2MiB devices or document the supported configuration. No closure action needed on either issue without that fix.
