Flashing issue using Zephyr & STLink

[vividhadhengre]

Hello,

We are migrating to zephyr, the board which is supported by zephyr is nucleo_g0b1re, but out actual controller is stm32g0c1ret3. Both are of same family, have same memory and all. I have just made changes in the overlay file for my application, have not touched anything in .dtsi or .dts file. I am facing issue when i try to dump code my my led which i have added in the overlay file. The error says "[stm32g0x.cpu] halted due to breakpoint, current mode: Handler HardFault". Can anyone tell what the possible ways can be due to which this error is occurring while flashing.

I have attached the screenshot of error.

What development host platform?

What tools & versions?

Can you program anything else using this environment? eg, an out-of-the-box example?

Can you program using STM32CubeProgrammer?

Have you tried asking at a Zephyr-specific forum?

It would be more helpful to post it as text - see:

Hello @vividhadhengre, 

According to the provided screenshot, you have a Hardfault probably due to mismatch between your .dts files and the actual layout of the STM32G0. Could you share your modified overlay files?
