This SDK has been patched by Embedded Artists for the iMXRT1064 Developer's Kit.
The SDK was released on 2024-03-25 and is based on NXP's 2.15.000 SDK (SDK_2_15_000_MIMXRT1064xxxxB.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
* 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

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

Hardware requirements
=====================
- MIMXRT1064-EVK board
- Personal Computer
- FreeMASTER 2.5 or later installed on PC
- Serial line, CAN or USB equipment as needed to connect over selected interface.

Board settings
============
By default, the demo is configured for standard serial (UART) communication. It may
be changed to other interface in MCUXpresso ConfigTools. Run the MCUXpresso ConfigTools, 
select the Peripherals tool and open the Middleware/FreeMASTER component configuration.
Refer to the list of recommended communication options below and make the selection in 
the FreeMASTER configuration page. Note that the other communication interfaces may require
to use different physical connections, such as CAN transceiver, serial or USB ports. 

Recommended communication options 
=================================
- 'SERIAL' at LPUART1 module connected to virtual serial port of the debugger USB interface.
- 'CAN' at CAN2 module, CAN transceiver is available on board at pins J11.
- 'Packet-driven BDM' using the debugger interface (use flash-based build targets only).

Prepare the demo
===============
1.  Interconnect the host PC and the target microcontroller board using the selected 
    interface cable.
2.  Compile and download the program to the target microcontroller.
3.  Run and resume application execution when debugger stops in the main() function.

If using the Packet-driven BDM interface
========================================
4.  Terminate the debugger session to release the JTAG interface for FreeMASTER use.
5.  Reset the target board to make sure it runs after detaching the debugger.

Connect with FreeMASTER
=======================
6.  Run FreeMASTER, use the Connection Wizard or open Project Options.
7.  Configure Serial, CAN or other communication as required by this demo setup.
8.  Start communication, FreeMASTER loads the initial TSA Active Content links in the Welcome page.
9.  Click the "FreeMASTER Demonstration Project (embedded in device)" in the Welcome page.
10. The demo is now running, you should be able to watch variable values and graphs.
