Flashing FRDM-MCXn947 with simple Hello World using Zephyr

elby — Mon, 12 May 2025 14:50:48 GMT

Hi, I am completely new to embedded development. I have got FRDM-MCXN947 micro controller where I wanted to flash a simple hello world application using Zephyr. I followed this link zephyrproject/frdm_mcxn947 to build and flash the board with the hello world application. All went well and here is the screen shot of output.

I am not sure if this one flashed the board with the hello-world program.

Then, I opened putty to see if I can get the Hello world printed in the terminal as seen here.

I didn't see the above message in serial terminal and it's blank.

NOTE: I would like to replicate this HTTP Server example once the hello-world example is working.

My goal is to learn, practice and understand the board with hello-world example before diving into HTTP Server example.

Thanks in Advance!

FYI,

Also, I tried flashing the board using LinkFlash software. Here is the attached output.

Confirm me if I am on the right path. My putty serial terminal is still empty and not seeing "Hello world" message when I hit reset button.

Hi @elby

If you build the hello world successfully.

When you connect the mcxn947 board.

You can open the device manager to check which COM port.

And then config the console.
