Our latest wifi-only modules are coming with ESP-WROVER-B module, and that includes 8MB PSRAM/SPIRAM (not 4MB, our standard so far). I have had one report from the field that factory firmware 3.2.002 works fine, but 3.2.005 crashes on boot with an error:
(824) psram: This chip is ESP32-D0WD[[0m
(824) spiram: Expected 4096KiB chip but found 8192KiB chip. Bailing out..
I see we have this in our sdkconfig:
Type of SPI RAM chip in use
( ) Auto-detect
(X) ESP-PSRAM32 or IS25WP032
( ) ESP-PSRAM64 or LY68L6400
Not sure when that appeared, but I guess between 3.2.002 and 3.2.005.
The user experiencing this problem is knowledgeable (he managed to recover back to factory), so I am trying a 3.2.007 build with him, with that setting set to auto-detect.
