Overview
========
The log Demo application demonstrates to prompt LOG with level by commands.
Note: Please input one character at a time. If you input too many characters each time, the receiver may overflow
because the low level UART uses simple polling way for receiving. If you want to try inputting many characters each time,
just define DEBUG_CONSOLE_TRANSFER_NON_BLOCKING in your project to use the advanced debug console utility.
Besides, the demo does not support semihosting mode. The log demo is based on shell, debug console and
serial manager. When semihosting is used, debug console and serial manager are bypassed. So the log demo cannot
work with semihosting.
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
- EVK-MIMXRT1020 board
- Personal Computer
Board settings
==============
No special settings are required.
Prepare the Demo
================
1. Connect a USB cable between the host PC and the OpenSDA USB port on the target 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. 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 demo.
Running the demo
================
When the example runs successfully, the following message is displayed in the terminal:

Note: The shell information "SHELL build: Sep 27 2020" may be different, which depends on the compile date.
Note:
To debug in qspiflash, following steps are needed:
1. Select the flash target and compile.
3. Set the SW8: 1 off 2 off 3 on 4 off, then power on the board and connect USB cable to J23.
4. Start debugging in IDE.
- Keil: Click "Download (F8)" to program the image to qspiflash first then clicking "Start/Stop Debug Session (Ctrl+F5)" to start debugging.
