Question

Nucleo-144 zephyr blinking example not working

I can build it successfully using west but when I program it I get: "Warning: The core is locked up" and no LED blinks.

I also made my own blinking LED but that doesn't work either.

I can program the board using stmcubeide and that work. It seems to be an stm32cubeprogrammer issue?

So what investigation/testing/debugging have you done to find why it's "not working" ?

 

How to write your question to maximize your chances to find a solution

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

I haven't gotten to debug it yet, I am new to Zephyr, I just wanted to try and run a simple application to begin with.
