The default configuration is set up run from IRAM. However, the
current (2016-11-14) OpenOCD for ESP32 does not support writing to
FLASH. This option sets up the linker scripts to support execution
from IRAM. In this case, OpenOCD can be used to load directly into
IRAM.
At this stage the nuttx image is small enough to be entirely memory-
resident. Once board support is more mature you can add flash cache
mapping code to run from SPI flash after initial boot. There are at
least two possible approaches you could take: You can add the flash
cache mapping code into nuttx directly, so it is self-contained -
early nuttx initialization runs from IRAM and enables flash cache,
and then off you go. Or you can use the esp-idf software bootloader
and partition table scheme and have nuttx be an esp-idf "app" which
allows interoperability with the esp-idf system but makes you
reliant on the esp-idf design for these parts. Both are possible.
config ESP32_ETHERNETKIT_FLASH_IMAGE

README for the Espressif ESP32 Ethernet Kit
==============================================
The ESP32 is a dual-core system from Espressif with two Harvard
architecture Xtensa LX6 CPUs. All embedded memory, external memory and
peripherals are located on the data bus and/or the instruction bus of
these CPUs. With some minor exceptions, the address mapping of two CPUs
is symmetric, meaning they use the same addresses to access the same
memory. Multiple peripherals in the system can access embedded memory via
DMA.
The ESP32-Ethernet-Kit is an Ethernet-to-Wi-Fi development board that enables
Ethernet devices to be interconnected over Wi-Fi. At the same time, to provide
more flexible power supply options, the ESP32-Ethernet-Kit also supports power
over Ethernet (PoE).
Buttons and LEDs
================
Buttons
-------
There are two buttons labeled Boot and EN. The EN button is not available
to software. It pulls the chip enable line that doubles as a reset line.
The BOOT button is connected to IO0. On reset it is used as a strapping
pin to determine whether the chip boots normally or into the serial
bootloader. After reset, however, the BOOT button can be used for software
input.
LEDs
----
There are several on-board LEDs for that indicate the presence of power
and USB activity. None of these are available for use by software.
Ethernet
========
ESP32 has a 802.11 hardware MAC, so just connects to external PHY chip.
Due to the limited number of GPIOs in ESP32, it's recommended to use RMII to
connect to an external PHY chip. Current driver also only supports RMII option.
The RMII GPIO pins are fixed, but the SMI and functional GPIO pins are optional.
RMII GPIO pins are as following:
ESP32 GPIO PHY Chip GPIO
IO25 <--> RXD[0]
IO26 <--> RXD[1]
IO27 <--> CRS_DV
IO0 <--> REF_CLK
IO19 <--> TXD[0]
IO21 <--> TX_EN
IO22 <--> TXD[1]
SMI GPIO pins (default option) are as following:
ESP32 GPIO PHY Chip GPIO
IO18 <--> MDIO
IO23 <--> MDC
Functional GPIO pins(default option) are as following:
ESP32 GPIO PHY Chip GPIO
IO5 <--> Reset_N
Espressif has an offcial Ethernet development board:

* matching application logic. The value could be such things as a

* pointer to configuration data read from a file or serial FLASH,
* or whatever you would like to do with it. Every implementation
* should accept zero/NULL as a default configuration.
*
* Returned Value:

* any failure to indicate the nature of the failure.
