What SPI flash settings to use for ESP-wroom-02 module?

2016-02-15T17:03:52+08:00

Hi Espressif,

I bought your ESP-wroom-02 module http://espressif.com/en/products/wroom/

What are the correct SPI parameters that I should use in the Makefile for your sdk sample app?

Currently, this is what I use.

SPI_SPEED ?= 40
SPI_MODE ?= dio
SPI_SIZE_MAP ?= 4

It seems to work fine. However, the confusing part is that when I use SPI_MODE ?= qio, the module also works fine. Which exactly are the correct parameters?

Thank you.
