SPI flash settings to use for ESP-wroom-02 module
Posted: Mon Feb 15, 2016 5:21 amI bought the ESP-wroom-02 module http://espressif.com/en/products/wroom/
What are the correct SPI parameters that I should use in the Makefile for a 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?
