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


This example has been configured to use the 1XK M.2 module. To change which
module to use, replace WIFI_IW416_BOARD_MURATA_1XK_M2 in the app_config.h file
with one of the following and then rebuild the project:

    WIFI_IW416_BOARD_MURATA_1XK_M2     - To use the 1XK M.2 module
    WIFI_88W8801_BOARD_MURATA_2DS_M2   - To use the 2DS M.2 module
    WIFI_88W8987_BOARD_MURATA_1ZM_M2   - To use the 1ZM M.2 module

The NXP EVK needs an 'Murata uSD M.2 Adapter' but the iMXRT1062 Developer's Kit
has an M.2 connector (J38) so the adapter is not needed. Please ignore all mentions
of the 'Murata uSD M.2 Adapter' and the 'receptable cables' below.

More information about the M.2 Modules can be found here: https://www.embeddedartists.com/m2/.

Everything below this line is the original content of the readme file.

Overview
========
This example demonstrates how the board can be controlled by Android mobile application with usage the AWS IoT.
User LEDs on the board can be controlled and also an action can be invoked to read data from accelerometer and report it to AWS IoT device shadow.
Please take look into section "Board settings" if there are some board limitations to control LEDs or read data from accelerometer.

Before building the example application select Wi-Fi module macro in the app_config.h. (see #define WIFI_<SoC Name>_BOARD_<Module Name>).
For more information about Wi-Fi module connection see:
    readme_modules.txt
    Getting started guide on supported modules configuration:

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 needs Wi-Fi network with internet access.
    Update these macros in "aws_clientcredential.h" based on your Wi-Fi network configuration:
        #define clientcredentialWIFI_SSID       "Paste Wi-Fi SSID here."
        #define clientcredentialWIFI_PASSWORD   "Paste Wi-Fi password here."

4.  Open example's project and build it.

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

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

7.  Download the program to the target board.

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


Prepare the Android application
The Android application requires Cognito service to authorize to AWS IoT in order to access device shadows. Use Amazon Cognito to create a new identity pool:

1.  In the Amazon Cognito Console https://console.aws.amazon.com/cognito/ select "Manage Federated Identities" and "Create new identity pool".

2.  Name your pool and ensure "Enable access to unauthenticated identities" is checked. This allows the sample application to assume the unauthenticated role associated with this identity pool.
    Note: to keep this example simple it makes use of unauthenticated users in the identity pool. This can be used for getting started and prototypes but unauthenticated users should typically only be given read-only permissions in production applications. More information on Cognito identity pools including the Cognito developer guide can be found here: http://aws.amazon.com/cognito/.

3.  To obtain the Pool ID constant, select "Edit identity pool" and copy Identity pool ID (it will look like <REGION>:<ID>). This Identity pool ID (<COGNITO POOL ID>) will be used in the application (policy and configuration file).

4.  To obtain Account ID, select account name in webpage menu bar and select "My account" from drop down menu. Make note of "Account ID" under "Account Settings".

5. As part of creating the identity pool Cognito will setup two roles in Identity and Access Management (IAM) https://console.aws.amazon.com/iam/home#roles. These will be named something similar to: "Cognito_PoolNameAuth_Role" and "Cognito_PoolNameUnauth_Role".
Create policy to be attached into "Cognito_PoolNameUnauth_Role" though "Policies" menu, selecting "Create policy", "Create Your Own Policy" and copying example policy below into "Policy Document" field and naming it for example "<THING NAME>Policy". Replace <REGION>, <ACCOUNT ID> and <THING NAME> with your respective values. This policy allows the application to get and update the two thing shadows used in this sample.

    {
        "Version": "2012-10-17",
        "Statement": [
            {
                "Effect": "Allow",
                "Action": [
                    "iot:Connect"
                ],
                "Resource": [
                    "*"
                ]
            },
            {
                "Effect": "Allow",
                "Action": [
                    "iot:Publish"
                ],
                "Resource": [
                    "arn:aws:iot:<REGION>:<ACCOUNT ID>:topic/$aws/things/<THING NAME>/shadow/update",
                    "arn:aws:iot:<REGION>:<ACCOUNT ID>:topic/$aws/things/<THING NAME>/shadow/get"
                ]
            },
            {
                "Effect": "Allow",
                "Action": [
                    "iot:Subscribe",
                    "iot:Receive"
                ],
                "Resource": [
                    "*"
                ]
            }
        ]
    }

6.  Newly created policy now needs to be attached to the unauthenticated role which has permissions to access the required AWS IoT APIs by opening "Cognito_PoolNameUnauth_Role" under "Roles" menu. Then in "Permissions" tab select "Attach policy" to view list of all AWS policies where example's policy "<THING NAME>Policy" needs to be selected though checking its checkbox and clicking on "Attach policy" button.

    More information on AWS IAM roles and policies can be found here: http://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_manage.html
    More information on AWS IoT policies can be found here: http://docs.aws.amazon.com/iot/latest/developerguide/authorization.html

7.  Prepare "AwsRemoteControlPreferences.properties" file with yours AWS credentials. It's structure looks like this:

    customer_specific_endpoint=<REST API ENDPOINT>
    cognito_pool_id=<COGNITO POOL ID>
    thing_name=<THING NAME>
    region=<REGION>

    Then move properties file into your Android device (application will ask for properties file though file browser dialog during first run).

8.  To run Android application do either:
    a) install and run pre-build apk on Android device (<SDK_Repository>\boards\<board_name>\aws_examples\remote_control\android\AwsRemoteControl.apk)
    b) open project in Android Studio, build it, attach Android device and Run application

    Application requires at least Android version 5.1 (Android SDK 22).

    Then in both cases when asked select AwsRemoteControlPreferences.properties file with AWS IoT preferences. Then application will establish MQTT connection to AWS server, download last state of thing's shadow and will be ready for user input.


Running the demo
================
The log below shows the output of the demo in the terminal window. The log can be different based on your Wi-Fi network configuration and based on the actions, which you have done in the Android application.

Android application displays Accelerometer data for all three axis and status of LEDs which is split into Desired and Reported section. Desired value is value wanted by user and Reported value is actual value of LEDs on device.

- When you turn on/off some of RGB LED in the Android application, the change should be visible on RGB LED on the board.
- When you refresh accelerometer data on Android application, you should see changes in the accelerometer data.

Every mentioned action takes approximately 1-3 seconds.
