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 WolfSSL SelfTest program performs cryptographic algorithm testing and prints results to the
terminal.


Toolchain supported
===================
- GCC ARM Embedded  10.3.1

Hardware requirements
=====================
- Mini/micro USB cable
- EVKB-MIMXRT1060 board
- Personal Computer

Board settings
==============
No special settings are required.
Prepare the Demo
================
Connect a serial cable from the debug UART port of the target board to the PC. Start TeraTerm
(http://ttssh2.osdn.jp) and make a connection to the virtual serial port.

1. Start TeraTerm.

2. New connection -> Serial.

3. Set the appropriate COMx port (where x is port number) in port context menu. The number is provided by the operating
   system, and could be different from computer to computer. Select the COM number related to the virtual
   serial port. Confirm the selected port by clicking the "OK" button.

4. Set following connection parameters in menu Setup -> Serial port.
        Baud rate:    115200
        Data:         8
        Parity:       none
        Stop:         1
        Flow control: none

5.  Confirm the selected parameters by clicking the "OK" button.

Running the demo
================
When the demo runs successfully, the terminal will display similar information like the following:
