Nios II code only working in debug mode.

I'm testing a very simple led blinking code. After programming the board, when I click "run" in eclipse, the led blinking code is not working at all. However, if I click "debug" and enter ste...

Hi @BigHandsomeBee,

Thank you for posting in Intel community forum and hope all is well.
A few clarification, is the programmer detecting the board? And did you managed to program the board with the .sof files?
Would also recommend to check for timing issues or unassigned pin.

I did managed to look into the project shared, however there seems to be multiple qsf files and failed to compile, can you share what are the targeted device and also quartus version used?
Hope to hear from you soon.

Best Wishes
BB

Hi @BoonBengT_Altera ,

Thanks for the reply!

I'm using Quartus Prime Pro 21.2 with Stratix 10 device.

I re-packed the project file deleting irrelevant files. Please find it in the attachment.

I'm pretty sure the .sof file is successfully programmed to the hardware.

Another thing that I have found recently is that if I downloaded the .elf code multiple times, e.g. type command "nios2-download -g xxxx.elf" in terminal multiple times,

occasionally the downloaded code can work while most of the time it does not work. No timing error was reported in the compilation report, so I'm not sure how this nondeterministic behavior happens.

Thank you.

Yu

    @BoonBengT_Altera

    Hello,

    I was wondering if you have successfully compiled the project and reproduced the error?

    Thank you.
