Problems with Hello World Rx

[jmreina]

We are getting started with the LPC55S06-EVK and having problems with the SDK's hello world.

Setup:

• MCUXpresso v11.7.0
• SDK v2.13.0
• LPC55S06-EVK

Working:

• Blinky demo
• Hello World console output "hello world."

Problem:

• Hello World console input - the input values are not received by GETCHAR() on hello_world.c:50

I smash the keyboard a lot, and nothing works. Have tried in PuTTy/Realterm too I'm desperate - thoughts? How do I get Rx working for this demo?

Thanks!

*I found the SDK's getting started reference but wanted to check here first, this was not expected!

It was just a jumper - JP12. Here is the ref:

• Serial Communication Issue on LPC55S06-EVK - NXP Community

Can you please provide explicit reference to JP12 in your documentation or source commentary for this demo?

Thanks!

Hello @jmreina 

Sorry for the inconvenient to you.

How about check user manual for "LPCXpresso55S06 Development Boards":

Hello @jmreina 

You can simple use the Terminal of MCUXpresso IDE:

Also pay attention please choose "UART console" with your project:

If still can't work, take a video or screenshot show your steps and take a photo about your board connection, thanks.
