This SDK has been patched by Embedded Artists for the iMXRT1064 Developer's Kit.
The SDK was released on 2022-03-15 and is based on NXP's 2.11.0 SDK (SDK_2_11_0_MIMXRT1064xxxxA.zip).

This is what has been patched:
* Set CPU speed according to Commercial/Industrial CPU
* Correction of the VDD_SOC_IN voltage.
* 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
* Added an I2C driver for the PWM gpio expander (PCA9530) and code to use it
* SEMC projects - changed algorithm for memory test and now test entire 32MB instead of only 4KB
* Examples using a display have been updated to use PCA6416/PCA9530 for
  RST/PWR/BL signals
* BOARD_USER_BUTTON has been redirected to SW5/WAKEUP button on the uCOM Carrier Board
* USER_LED has been changed to the blue RGB LED using PCA6416
* Adjusted the USB interface number (it is different for host and device examples)
* Changed the Wi-Fi examples to use the Embedded Artists 1XK M.2 Module (EAR00385) as default
* Added support for Embedded Artists 1ZM M.2 Module (EAR00364) in the NXP Wi-Fi examples
* 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).
* Changed reset pin for SD card examples

This has been added:
* LWIP projects - option to use 100/10Mbps Ethernet-PHY Adapter
* AWS projects - option to use 100/10Mbps Ethernet-PHY Adapter
* AzureRTOS projects - option to use 100/10Mbps Ethernet-PHY Adapter
* I2C probe example
* Wi-Fi (serial) examples for the CMWC1ZZABR-107-EVB (a.k.a ABR Module)

This has been removed:
* All projects for the expansion board AGM01

Important things to note:
* Read section "8 - Known Issues" in docs/MCUXpresso SDK Release Notes for EVK-MIMXRT1064.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:
* J29 (micro USB) is the default UART and unless specified otherwise it is setup for 115200 8/N/1


!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
THIS PROJECT IS NOT DIRECTLY COMPATIBLE WITH THE HARDWARE AND WILL NOT WORK.

There is no CAN tranciever mounted on the uCOM Carrier Board

Overview
========
The flexcan_interrupt example shows how to use FlexCAN driver in none-blocking interrupt way:

In this example, 2 boards are connected through CAN bus. Endpoint A(board A) send a CAN Message to
Endpoint B(board B) when user press space key in terminal. Endpoint B receive the message, print
the message content to terminal and echo back the message. Endpoint A will increase the received
message and waiting for the next transmission of the user initiated.

For self wake up from STOP mode, since steps which MCU enters STOP mode differs on different MCUs,
take flexcan_interrupt_transfer of twrke18f for example, user should do like this:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#include "fsl_smc.h"
...
...
flexcanConfig.enableSelfWakeup = true;
FLEXCAN_Init();
...
...
SMC_SetPowerModeStop(SMC, kSMC_PartialStop1);
if (wakenUp)
{
    PRINTF("B has been waken up!\r\n\r\n");
}
...
...
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Toolchain supported
===================
- MCUXpresso  11.5.0
- GCC ARM Embedded  10.2.1
- IAR embedded Workbench  9.10.2
- Keil MDK  5.34

Hardware requirements
=====================
- Mini/micro USB cable
- EVK-MIMXRT1064 board
- Personal Computer

Board settings
==============
The example requires 2 sets of boards, each of them are mounted with the base board. Using a male to male CAN
cable to connect the CAN2 instance (J11) between the 2 base boards.

Prepare the Demo
================
1. Connect a USB cable between the PC host and the OpenSDA USB on the board.
2. 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
3. Download the program to the target board.
4. Either press the reset button on your board or launch the debugger in your IDE to begin running
   the example.

Running the demo
================
After connecting the two boards, these instructions display on each terminal window.
One board must be chosen as node A and the other board as node B. (Note: Node B should start first)
Data is sent continuously between the node A and the node B.

~~~~~~~~~~~~~~~~~~~~~
Consider special errata 005829 feature, the 1st valid MB should be used as reserved one.
The TX MB number will change from 8 to 9, while RX MB number will change from 9 to 10 
This message displays on the node A terminal:

    Message format: Standard (11 bit id)

    Message buffer 10 used for Rx.

    Message buffer 9 used for Tx.
