This SDK has been patched by Embedded Artists for the iMXRT1064 Developer's Kit.
The SDK was released on 2022-03-15 and is based on NXP's 2.11.0 SDK (SDK_2_11_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
* 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
* SEMC projects - changed algorithm for memory test and now test entire 32MB instead of only 4KB
* Examples using a display 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)
* Changed the Wi-Fi examples to use the Embedded Artists 1XK M.2 Module (EAR00385) as default
* Added support for Embedded Artists 1ZM M.2 Module (EAR00364) in the NXP Wi-Fi examples
* Many of the projects have been updated to use a more complete pin_mux.c file where all
  necessary pins have been initialized. The SDK examples used to only configure the pins
  that they use (and often not every pin) and most of the time the configuration was only
  for MUX:ing and not the PAD settings (pull up/down/none, drive strength and slew).
* 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 extended to support two different network options:

Option1: (default) uses the 100/10Mbit Ethernet PHY on the iMX RT1064 uCOM board
         and the connector on the uCOM Carrier Board
Option2: uses the 100/10Mbit Ethernet-PHY Adapter board

For examples that support both options, select which option to use by changing
this define in board.h:

#define BOARD_NETWORK_USE_ONBOARD_100M_ENET_PORT (1U)

Some of the network examples have been modified to obtain the globally unique
MAC address from an EEPROM either on the 100/10Mbit Ethernet-PHY Adapter board
or on the iMX RT1176 uCOM board depending on which interface is used.

=======================================================================



Overview
========
This is a small Iperf demo of the high-performance NetX Duo TCP/IP stack.


Toolchain supported
===================
- IAR embedded Workbench  9.10.2
- Keil MDK  5.34
- GCC ARM Embedded  10.2.1
- MCUXpresso  11.5.0

Hardware requirements
=====================
- Mini/micro USB cable
- Network cable RJ45 standard
- EVK-MIMXRT1064 board
- Personal Computer

Board settings
==============
No special settings are required.

Prepare the Demo
================
1.  Connect a USB cable between the host PC and the OpenSDA USB port on the target 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.  Insert Cable to Ethernet RJ45 port and connect it to a ethernet switch.
4.  Write the program to the flash of the target board.
5.  Press the reset button on your board to start the demo.

Running the demo
================
1. When the demo is running, the serial port will output:

Start the iperf example...
DHCP In Progress...
IP address: 192.168.2.10
Mask: 255.255.255.0

2. The board gets a new IP address, for example, 192.168.2.10. On a Linux PC, open a Web browser to
access the new IP address at http://192.168.2.10, and a iperf test Web page will display.

3. To start a UDP iperf test, run the iperf command in a command console on the Linux PC. For example,

  $ iperf -u -s -i 1

4. In the iperf test Web page, click the "Start UDP Transmit Test" button. The test
will begin.

5. When the test is finished, click the "here" in the right side of the Web page.
It shows the test result like:

UDP Transmit Test Done:

Destination IP Address: 192.168.2.18
Test Time(milliseconds): 10000
Number of Packets Transmitted: 30328
Number of Bytes Transmitted: 44582160
Throughput(Mbps):35
