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 lwip_httpsrv_mbedTSL_bm demo application demonstrates an HTTPS Server
set up on lwIP TCP/IP and the mbedTLS stack with bare metal. The user
uses an Internet browser to send an https request for connection.
The board acts as an HTTPS server and sends a Web page back to the PC.


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

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

Prepare the Demo
================
1.  Connect a mini USB cable between the PC host and the OpenSDA(or USB to Serial) USB port on the board.
2.  Open a serial terminal on PC for OpenSDA serial(or USB to Serial) device with these settings:
    - 115200 baud rate
    - 8 data bits
    - No parity
    - One stop bit
    - No flow control
3.  Insert Cable to Ethernet RJ45 port and connect it to your PC.
4.  Configure ip address of PC to 192.168.0.100 .
5.  Open a web browser.
6.  Download the program to the target board.
7.  Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.

Running the demo
================
1.  When the demo runs successfully, the terminal will display the following:
		Initializing PHY...

		************************************************
		 mbedTLS HTTPS Server example
		************************************************
		 IPv4 Address     : 192.168.0.102
		 IPv4 Subnet mask : 255.255.255.0
		 IPv4 Gateway     : 192.168.0.100
		************************************************
2.  On the browser address bar, type https://192.168.0.102 (ip address of the board).
    The browser should respond as shown below:

		lwIP - A Lightweight TCP/IP stack

		The web page you are watching was served by a simple web server running on top of the lightweight TCP/IP stack lwIP.

		lwIP is an open source implementation of the TCP/IP protocol suite that was originally written by Adam Dunkels of
		the Swedish Institute of Computer Science but now is being actively developed by a team of developers distributed
		world-wide.Since it's release, lwIP has spurred a lot of interest and has been ported to several platforms and
		operating systems. lwIP can be used either with or without an underlying OS.

		The focus of the lwIP TCP/IP implementation is to reduce the RAM usage while still having a full scale TCP. This
		makes lwIP suitable for use in embedded systems with tens of kilobytes of free RAM and room for around 40 kilobytes
		of code ROM.

		More information about lwIP can be found at the lwIP homepage at http://savannah.nongnu.org/projects/lwip/ or at
		the lwIP wiki at http://lwip.wikia.com/.
