HardFault with example_pointer(); in STM32, using DWM3000evb

I’m currently encountering the HardFault_Handler, when I run the example code for STM32.

When I run the example_handler, I get caught hardfault_handler immediately.

What’s the problem?

Hi @Adam12, can you share more details to help us reproduce the issue? Which SDK are you using and which example are you running?

Thanks for replying.

I have resolved the previous HardFault issue, but I am now experiencing difficulties running the DS_TWR example.

To monitor the communication flow, I am using Tera Term, and I can see that the poll → response → final sequence is being executed correctly (the initiator side confirms sending the final flag).

However, on the responder side, it seems that the message is not being properly received. The sys status shows 0x00000106 and 0x00000306, and it outputs a “flag err” message.

Based on my research, these statuses appear to be related to signal quality issues. Could running two STM boards and two DWM3000EVB boards from a single laptop cause a power supply problem?
