FRDM-KL25Z with UART0 Polling SDK

hvidales — Fri, 28 Jun 2024 23:18:35 GMT

Dear all,

I just purchased the FRDM-KL25Z board, and I am trying to run the UART Polling SDK example with some minor adjustments. The UART example for KL25Z is using UART1 but I am trying to implement it with UART0 (Open SDA). I updated the code(attached) and updated the pins(picture attached) to use UART0 and not UART1. I can build the project fine, but the issue is when I try to debug it by pressing the green button it won't follow through the debug process. It gets stuck. I have also attached a video showing the issue. How can I fix this? Any help is appreciated.

Hello @hvidales

Please check whether enabled PORT clock and configured pin as UART functions.

If it still can't work, please erase whole chip. Change a now MCUXpresso IDE workspace. Create a new project or import your project. Try to debug again.
