TWR-KV58 Hard Fault

pietrodicastri — Tue, 16 Dec 2025 09:44:42 GMT

Good morning

I have a remarkable error on the TWR board. I used this board in the same condition previously and it worked, It was standing there for a while and now I start directly with a hard fault.
I am using the Multilink with the JTAG cable connected. I did previously. I start directly in a hard fault.
That's the screen shot

The jumper J19 and J20 are open for using the JTAG. It should be enough.
Please suggest something. I can only suppose it is broken..

Thank You everyone

Pietro

Good morning
Please just support me. I have already ordered a new one as a backup solution, but I need a help for proceeding.
Thank You

Hello @pietrodicastri ,

Thanks for your post. To help determine whether this is a software issue, could you please check if the HardFault still occurs when running the demo included in the SDK, such as the “Hello World” demo?

SDK link: Select Board | MCUXpresso SDK Builder

You may refer to https://www.keil.com/appnotes/files/apnt209.pdf to know more details.
