XRT1042 Stack Overflow when _main() function is called

riccardo_carlot — Thu, 09 Nov 2023 09:11:51 GMT

Hello,

I'm working with a new project based on MIMXRT1040-EVK, I'm facing with a problem of Stack Overflow, it happens when the Rest_ISR() calls the main() function.

Here the screenshot setting the breakpoint before the main() call and just after that.

What is happening? What could I check?

Thank you a lot.

Regards

Hi @riccardo_carlot

I hope that you are doing well!

I did a sanity test on my side with the following setup, but I did not saw this issue.

Did you make any special setup to your project? Any changes in the linker etc?

All the best,

Diego

Hello Diego,

thank for your interest, I'm sorry for my late, I didn't receive the notify through email.

The strange is that the code runs well also in overflow. I didn't touch the linker configuration or some other setting, just created a new project and start using a simple SPI.

The problem, now, is that the issue dissappeared. I worked this week regardless the stack overflow, this morning I would have shared the project with you, so I checked the problem again but now I don't have anythig to show with you, it works properly.

I don't want to waste your time, I will open the topic again as soon as the problems comes out.

Thank you so much.
