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 demo implements a simple web based Wi-Fi configuration utility for connecting the board to the local Wireless network. 

Initially, the board doesn't have the credentials to join the local network, so it starts its own Access Point with SSID: "nxp_configuration_access_point" and password: "NXP0123456789".

The user can connect their device to this SSID and access the HTML UI under 192.168.1.1. The board will scan for the nearby Wi-Fi networks and display a list of them on this page. By clicking on the entries, the user can choose their network, enter the credentials and connect. The board will attempt to join this Wi-Fi network as a client and if it succeeds, it will disconnect its AP and save the credentials to its mflash memory.

On successive restarts, it checks the mflash memory and uses the saved credentials to directly connect to the local Wi-Fi network without starting the AP. 

A simple LED visualization is implemented. The board LED will be on if the device is in AP mode and turns off after the board changes to client mode.

The site allows the user to clear the credentials from the flash memory and reset the board to AP mode. If connection fails, user can also set device to AP mode through serial connection.

The source files for the web interface are located in the webui directory. Use the `<path_to_sdk>/middleware/lwip/src/apps/httpsrv/mkfs/mkfs.pl webui` Perl script in order to convert the webui files into the httpsrv_fs_data.c which is used in order to flash the static files onto the board. Make sure the mkfsl.pl script is executed from the same directory where the file httpsrv_fs_data.c and the directory webui are.

Note that Microsoft Internet Explorer is not supported by this webconfig example.
