Same codes and project file, but hardfault on other PCs

[it0406]

Hello Devzome Users,

I have a problem with running my codes on other computers. The project runs on my PC very well which I coded original.

I would like to test it on other computers. I got always hardfault problem. If I want to debug it, I have to select or open thumb_crt0.s.

I could see the file in the project folder which doesn't actually have it and also the other folders.

If I select the file, the code goes into Hardfault.

Can someone answer it why it happens and how to solve it?

Segger Embedded Studio for ARM 5.50b

SDK: nRF5 SDK 17.0.2

Softdevice: s140

Best regards

Add your own HardFault_Handler() to your code. This way the code won't end up in the default Handler. Can help debugging if - and only if - the stack was still OK.

The default handler for faults (and undefined interrupts) resides in thumb_crt0.s source file IIRC.

Thank you for the reply.

As I know, hardfault means unrecoverable system failures.

Can I ignore it just with a hardfault handler? Or do you mean some hardfault cases in the handler and should the debug be stopped in this handler?

Should I modify something in the file?

I agree with Turbo J. If the stack is indeed okay, adding a hardfault handler of your own should help debugging here. Does default SDK examples also hardfault on this one computer or is it just your specific example project?

Best regards,

It is just my example project, but based on a SDK example. I just added some lines for my work.

I didn't try it with default SDK examples.
