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

Overview
========
The ccm_clockout driver example shows how to output the internal clock signal. In this driver example, users can choose
the clock signal to be outputted, and the divider of the output clock signal. By probing the output pin, users can
observe the selected internal clock signal.
Please note that different targets may have different default clock configurations, so the frequency of the same clock
root may be different in different targets even though the dividers are set as the same value.

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

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

Board settings
==============

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.  Download the program to the target board.
4.  Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.

Running the demo
================
To measure the output signal of CLKO1, please use the oscilloscope to probe TP27;
To measure the output signal of CLKO2, please use the oscilloscope to probe TP28.
These instructions are displayed/shown on the terminal window:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Clock Output Driver Example.
Please Choose one clock to be outputted on CLKO1.
        A -- USB1 PLL Clock(Divided by 2).
        B -- SYS PLL Clock(Divided by 2).
        C -- VIDEO PLL Clock(Divided by 2).
        D -- Semc Clock Root.
        E -- Lcdif Pix Clock Root.
        F -- AHB Clock Root.
        G -- IPG Clock Root.
        H -- Perclk Root.

a

Please set the clock divider, range from 1 to 8.
5

Theoretically, the output frequency of CLKO1 is 48000000 Hz.
