Build instructions

MCUXpresso SDK build

Please refer to the Getting Started with MCUXpresso SDK for EVK-MIMX8ULP and EVK9-MIMX8ULP.pdf included in the official SDK package for SDK build and deployment instructions. The Cortex-M33 application needed for this application note should be copied directly into the SDK's sensorhub_example folder:

cd <SDK path>/boards/evkmimx8ulp/demo_apps/
cp -r <path to imx8ulp_sensorhub folder>/imx8ulp_sensorhub/ .

Build the application using IAR or using the armgcc build_debug.sh script:

cd <SDK path>/boards/evkmimx8ulp/demo_apps/imx8ulp_sensorhub/armgcc/
./build_debug.sh

Prepare the Demo

1. Connect 5V power supply and J-Link Debug Probe to the board, switch SW10 to power on the board.
2. Connect a micro USB cable between the host PC and the J17 USB port on the target board.
3. Open a serial terminal with the following settings:
   • 115200 baud rate
   • 8 data bits
   • No parity
   • One stop bit
   • No flow control
4. Download the program to the target board.
