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/.

Overview
========
This is a simpe wifi setup demo.

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

    https://www.nxp.com/document/guide/getting-started-with-nxp-wi-fi-modules-using-i-mx-rt-platform:GS-WIFI-MODULES-IMXRT-PLATFORM



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

Hardware requirements
=====================
- Micro USB cable
- evkbmimxrt1060 board
- Personal Computer


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


Prepare the Demo
================
1.  Connect a micro USB cable between the PC host and the CMSIS DAP USB port on the 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.  Connect the WiFi module to SD card slot.
4.  Download the program to the target board.
5.  Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.


Running the demo
================
1. Adjust the SSID and PASSPHRASE definition to fit your wifi network and adjust the ping address definitions.
2. After wifi is initialized, it'll try to scan nearby networks. After the scan results appear press any key to continue.
3. Wifi will now try to connect to the defined network. After that you'll be one more time prompted to press any key.
