Hardware requirements

• Mini/micro USB cable

• EVK-MIMXRT1015 board

• Personal Computer

• USB to Com Converter

Board settings

Connect pin:

• RX of USB2COM to J17-4

• TX of USB2COM to J17-3

• GND of USB2COM to J19-7

Prepare the Demo

1. Connect the USB2COM Converter to the host PC

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 demo runs successfully, the log would be seen on the UART Terminal port which connected to the USB2COM like:

FLEXIO UART RX ring buffer example
Send back received data
Echo every 8 bytes

Note: To debug in qspiflash, following steps are needed:

1. Select the flash target and compile.

2. Set the SW8: 1 off 2 off 3 on 4 off, then power on the board and connect USB cable to J41.

3. 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.
