This SDK has been patched by Embedded Artists for the iMXRT1062 Developer's Kit.
The SDK was released on 2022-11-18 and is based on NXP's 2.12.1 SDK (SDK_2_12_1_MIMXRT1062xxxxA.zip).

This is what has been patched:
* Set CPU speed according to Commercial/Industrial CPU
* Correction of the VDD_SOC_IN voltage.
* Flash settings (speed, algorithm, size, driver) to work with the 4MB OctalSPI ATXP032
* 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
* Modified pin muxing
* SEMC projects - changed algorithm for memory test and now test entire 32MB instead of only 4KB
* Adjusted the USB interface number for USB Host examples (it is different for host and device examples)
* Added a software_reset() function in board.c/.h to issue a JEDEC reset before NVIC_SystemReset()
* 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).
* Embedded Wizard project 'ew_gui_smart_thermostat' was incorrectly setup for EVKB
* Changed the default display to RK043FN02H as it is the one mounted on the Developer's Kits

This has been added:
* New WDOG examples that work
* I2C probe example
* Example to show the use of software_reset()

This has been removed:
* All projects for the EVK - only keeping EVKB which is then patched
* The original WDOG and RTWDOG examples as those were not working

Important things to note:
* Read section "8 - Known Issues" in docs/MCUXpresso SDK Release Notes for EVK-MIMXRT1060.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:
* J22 (micro USB) is the default UART and unless specified otherwise it is setup for 115200 8/N/1

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



Overview
========
The simple Shadow lightbulb example to illustrate how client application and things communicate with the Shadow service.


Toolchain supported
===================
- IAR embedded Workbench  9.30.1
- Keil MDK  5.37
- GCC ARM Embedded  10.3.1
- MCUXpresso  11.6.0

Hardware requirements
=====================
- Mini/micro USB cable
- MIMXRT1060-EVKB board
- Personal Computer
- Network cable RJ45 standard (Network with Internet access)

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

Prepare the Demo
================
Before running the demo it is need to configure AWS IoT Console and update some of project files:

1.  Create AWS Account: https://console.aws.amazon.com/console/home

2.  Configure device in the AWS IoT Console base on this guide: https://docs.aws.amazon.com/iot/latest/developerguide/iot-sdk-setup.html

    Make note of example's "Thing name" and "REST API endpoint". These strings need to be set in the "aws_clientcredential.h".

    Example:
        static const char clientcredentialMQTT_BROKER_ENDPOINT[] = "abcdefgh123456.iot.us-west-2.amazonaws.com";
        #define clientcredentialIOT_THING_NAME "MyExample"

    In the next step you will get the "device certificate" and the "primary key". The device certificate and private key needs to be opened in text editor and its content copied into the "aws_clientcredential_keys.h".
    Or you can use the CertificateConfigurator.html (mcu-sdk-2.0\rtos\freertos\tools\certificate_configuration) to generate the "aws_clientcredential_keys.h".

    Example:
        #define keyCLIENT_CERTIFICATE_PEM "Paste client certificate here."

        Needs to be changed to:

        #define keyCLIENT_CERTIFICATE_PEM "-----BEGIN CERTIFICATE-----\n"\
        "MIIDWTCCAkGgAwIBAgIUfmv3zA+JULlMOxmz+upkAzhEkQ0wDQYJKoZIhvcNAQEL\n"\
        .
        .
        .
        "mepuT3lKmD0jZupsQ9vLQOA09rMjVMd0YPmI9ozvvWqLpjVvNTKVhsf/3slM\n"\
        "-----END CERTIFICATE-----\n"

    In the same way update the private key array.

3.  This demo doesn't need Wi-Fi network, you can leave the following macros from "aws_clientcredential.h" unmodified.
        #define clientcredentialWIFI_SSID       "Paste Wi-Fi SSID here."
        #define clientcredentialWIFI_PASSWORD   "Paste Wi-Fi password here."

4.  Make sure you have Internet access.

5.  Open example's project and build it.

6.  Connect a USB cable between the PC host and the OpenSDA port on the target board.

7.  Download the program to the target board with the CMSIS-DAP or J-Link debugger.

8.  Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.

9.  Open a serial terminal on PC for serial device with these settings:
    - 115200 baud rate
    - 8 data bits
    - No parity
    - One stop bit
    - No flow control

Running the demo
================
The log below shows the output of the demo in the terminal window. The log can be different based on your local network configuration.
