Winbond’s New Low-Voltage NOR Flash Memories Designed Around ESP32 comes to the market in the form of a module as soon as possible.

we have then a new ESP32 that can regulate 1.2V and 1.5V from intern regulator? 1.8V ? and 3.3V ? or new Low Voltage ESP32?
how we work this out with pSRAM 1.8V or comes 1.2V and 1.5V other in 2018 ?

we was happy to find working 1.8V(3.3V) pSRAM and in 2018 we start again with searching and waiting? :roll:
we started allready in time with 1.8V ...

best wishes

So do I need to compile the xtensa toolchain on Windows for pSRAM support now?
Or it is already in xtensa-esp32-elf-win32-1.22.0-73-ge28a011-5.2.0.zip // esp32_win32_msys2_environment_and_toolchain-20170918.zip ?

How about esp-idf? Do I need to checkout the feature/psram_malloc branch now? Or I can already use pSRAM with master branch? (I can see SPI RAM option in menuconfig with master branch already).

You should be able to use all the (latest) vanilla toolchain and esp-idf branches to use psram. Support is in mainstream now, and the specific psram branches have been deprecated.
