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 demo implements a simple web based Wi-Fi configuration utility for connecting the board to the local Wireless network. 

Initially, the board doesn't have the credentials to join the local network, so it starts its own Access Point with SSID: "nxp_configuration_access_point" and password: "NXP0123456789".

The user can connect their device to this SSID and access the HTML UI under 192.168.1.1. The board will scan for the nearby Wi-Fi networks and display a list of them on this page. By clicking on the entries, the user can choose their network, enter the credentials and connect. The board will attempt to join this Wi-Fi network as a client and if it succeeds, it will disconnect its AP and save the credentials to its mflash memory.

On successive restarts, it checks the mflash memory and uses the saved credentials to directly connect to the local Wi-Fi network without starting the AP. 

A simple LED visualization is implemented. The board LED will be on if the device is in AP mode and turns off after the board changes to client mode.

The site allows the user to clear the credentials from the flash memory and reset the board to AP mode. If connection fails, user can also set device to AP mode through serial connection.

The source files for the web interface are located in the webui directory. Use the `<path_to_sdk>/middleware/lwip/src/apps/httpsrv/mkfs/mkfs.pl webui` Perl script in order to convert the webui files into the httpsrv_fs_data.c which is used in order to flash the static files onto the board. Make sure the mkfsl.pl script is executed from the same directory where the file httpsrv_fs_data.c and the directory webui are.

Note that Microsoft Internet Explorer is not supported by this webconfig example.

Before building the example application select Wi-Fi module macro in the app_config.h. (see #define WIFI_<SoC Name>_BOARD_<Module Name>).
