Hardware requirements
Mini/micro USB cable
MIMXRT1024-EVK board
Personal Computer
Board settings
ADC1_IN10 and ADC1_IN11 are ADC inputs. Please sample voltage by J18-2 and J18-4 pins.
Prepare the Demo
Connect a USB cable between the host PC and the OpenSDA USB port on the target board.
Open a serial terminal with the following settings:
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
Download the program to the target board.
Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
Running the demo
The log below shows the output of the hello world demo in the terminal window:

Note: To debug in qspiflash, following steps are needed:
Select the flash target and compile.
Set the SW8: 1 off 2 off 3 on 4 off, then power on the board and connect USB cable to J23.
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.
