This SDK has been patched by Embedded Artists for the iMXRT1064 Developer's Kit.
The SDK was released on 2021-12-01 and is based on NXP's 2.10.0 SDK (SDK_2_10_0_MIMXRT1064xxxxA.zip).

This is what has been patched:
* Set CPU speed according to Commercial/Industrial CPU
* Correction of the VDD_SOC_IN voltage.
* LWIP projects - added reading of the MAC address from the onboard I2C EEPROM
* Wi-Fi and Bluetooth projects
* Added an I2C driver for the gpio expander (PCA6416) and code to use it
* Added an I2C driver for the PWM gpio expander (PCA9530) and code to use it
* Modified pin muxing
* SEMC projects - changed algorithm for memory test and now test entire 32MB instead of only 4KB
* Examples using a disaplay have been updated to use PCA6416/PCA9530 for
  RST/PWR/BL signals
* BOARD_USER_BUTTON has been redirected to SW5/WAKEUP button on the uCOM Carrier Board
* USER_LED has been changed to the blue RGB LED using PCA6416
* Adjusted the USB interface number (it is different for host and device examples)
* Added support for Embedded Artists 2DS M.2 Module (EAR00386) in the NXP Wi-Fi examples
* Added support for Embedded Artists 1ZM M.2 Module (EAR00364) in the NXP Wi-Fi examples
* Added support for Embedded Artists 1XK M.2 Module (EAR00385) in the NXP Wi-Fi examples
* Changed reset pin for SD card examples

This has been added:
* LWIP projects - option to use 100/10Mbps Ethernet-PHY Adapter
* AWS projects - option to use 100/10Mbps Ethernet-PHY Adapter
* AzureRTOS projects - option to use 100/10Mbps Ethernet-PHY Adapter
* I2C probe example
* Wi-Fi (serial) examples for the CMWC1ZZABR-107-EVB (a.k.a ABR Module)

This has been removed:
* All projects for the expansion board AGM01

Important things to note:
* Read section "8 - Known Issues" in docs/MCUXpresso SDK Release Notes for EVK-MIMXRT1064.pdf
  to see known issues with the current version of the SDK.
* For Iperf examples, set compiler optimization to -O3 or similar to improve performance.
* If the hardware seems unresponsive and the debugger cannot connect/flash/erase the current program
  then the most likely cause is the running program preventing the access. To stop the currently
  running program and regain control:
  1) Press and hold down the ISP_ENABLE button (SW1)
  2) Press and hold down the RESET button (SW3)
  3) Let go of the RESET button
  4) Wait an extra second or two
  5) Release the ISP_ENABLE button
  6) The hardware is now in a mode where programming/erasing it should work



Connectors:
* J29 (micro USB) is the default UART and unless specified otherwise it is setup for 115200 8/N/1


This example has been configured to use the 1XK (IW416 or 88W8978) M.2 module. To change
which module to use, replace WIFI_BOARD_EA_1XK_M2_88W8978_IW416 in the app_config.h file
with one of the following and then rebuild the project:

    WIFI_BOARD_EA_1XK_M2_88W8978_IW416   - To use the 1XK M.2 module
    WIFI_BOARD_EA_2DS_M2_88W8801         - To use the 2DS M.2 module
    WIFI_BOARD_EA_1ZM_M2_88W8987         - To use the 1ZM M.2 module

This example requires an M.2 Module and a uSD-M2 Adapter (LBEE0ZZ1WE-TEMP)
from Murata inserted in uSD connector J34. The M.2 socket (J33) on the uCOM Carrier Board
is not used.

The uSD-M2 Adapter must be configured with:
J1  shorted in 1-2 position
J12 shorted in 2-3 position
J13 shorted in 1-2 position
J9 pin 3 must be connected to J32 pin 2 (INT) on the uCOM Carrier Board with a cable.

Due to high current consumption peaks of the M.2 module, especially during startup calibration,
you must power the uSD-M2 Adapter from an external source. The power supply from the uSD
interface is not enough. Connect a USB cable to the micro-B USB connector on the uSD-M2 Adapter,
in one end, and a PC, USB Hub or USB charger in the other end.

The BLUE LED on the uSD-M2 Adapter should be on if the adapter is configured correctly.

More information about the M.2 Modules can be found here: https://www.embeddedartists.com/m2/.
More information about the uSD-M2 Adapter can be found here: https://wireless.murata.com/usd-m2.html.

It could be possible to use the other modules as shown in the original
readme text below, however that is untested and unsupported.

Everything below this line is the original content of the readme file.

Overview
========
This is a simpe wifi setup demo.


Toolchain supported
===================
- IAR embedded Workbench  9.10.2
- Keil MDK  5.34
- GCC ARM Embedded  10.2.1
- MCUXpresso  11.4.0

Hardware requirements
=====================

  - Panasonic PAN9026 SDIO ADAPTER + SD to uSD adapter
  - AzureWave AW-NM191NF-uSD
  - AzureWave AW-AM457-uSD
  - AzureWave AW-CM358-uSD

Board settings
==============
This example, by default, is built to work with the AzureWave AW-AM457-uSD. It is configured by the macro definition in file app_config.h (#define WIFI_BOARD_AW_AM457).
If you want use the AzureWave AW-NM191NF-uSD, please change the macro to WIFI_BOARD_AW_NM191.
If you want use the Panasonic PAN9026 SDIO ADAPTER, please change the macro to WIFI_BOARD_PAN9026_SDIO.
If you want use the AzureWave AW-CM358-uSD, please change the macro to WIFI_BOARD_AW_CM358.

Jumper settings for AzureWave AW-NM191NF-uSD Module:
  - J11 1-2: VIO_SD 1.8V (Voltage level of SDIO pins is 1.8V)
  - J2  1-2: 3.3V VIO_uSD (Power Supply from uSD connector)

Jumper settings for AzureWave AW-AM457-uSD Module:
  - J11 1-2: VIO_SD 1.8V (Voltage level of SDIO pins is 1.8V)
  - J2  1-2: 3.3V VIO_uSD (Power Supply from uSD connector)

Jumper settings for AzureWave AW-CM358-uSD Module:
  - J4 1-2: VIO 1.8V (Voltage level of SDIO pins is 1.8V)
  - J2 1-2: 3.3V VIO_uSD (Power Supply from uSD connector)
  - The pin 1 of J4 is not marked on the board. Please note that pin numbering of J4 is opposite to J2 (pin 1 is close to the "J4" label):
         3 2 1
         o o=o J4
      J2 o=o o
         1 2 3

Prepare the Demo
================
1.  Connect a micro USB cable between the PC host and the CMSIS DAP USB port on the board
2.  Open a serial terminal with the following settings:
    - 115200 baud rate
    - 8 data bits
    - No parity
    - One stop bit
    - No flow control
3.  Connect the WiFi module to SD card slot.
4.  Download the program to the target board.
5.  Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.


Running the demo
================
1. Adjust the SSID and PASSPHRASE definition to fit your wifi network and adjust the ping address definitions.
2. After wifi is initialized, it'll try to scan nearby networks. After the scan results appear press any key to continue.
3. Wifi will now try to connect to the defined network. After that you'll be one more time prompted to press any key.
