The button interrupt enters the spurious handler

[jasonedn]

Describe the bug
The button sample ran on the board nucleo_l476rg, When the button was pressed, it entered the spurious handler instead of the button handler.

To Reproduce
Build the button sample on the board nucleo_l476rg with the command:
west build -p auto -b nucleo_l476rg samples/basic/button

Expected behavior
When the blue button is pressed, it entered the spurious handler and stuck there.

Impact

Screenshots or console output
With the debugger, the address of _sw_isr_tables is 0x08003424 and the offset of GPIO exti_15_10 is 40*8=0x140, so the exti_15_10 address in the table is 0x08003564. From the data below, the ISR address of exti_15_10 is 0x08002BCF that points to the spurious handler instead of the button handler.

However according to the generated isr_tables.c, _sw_isr_table is initialized correctly (offset=40) as below.

Additional context

When the codes are downloaded, I set the content @0x8003564 in _sw_isr_tables to (0x2000104c, 0x08002B67) from the source codes, it entered the desired button handler.

Why are the source codes correct but the built binary is not?

[jasonedn]

This issue occurred in Windows but it worked in Linux platform.

[erwango]

^^@ABOSTM, can you have a check on your side ?

[ABOSTM]

Hi @jasonedn,
I tested on my side, and I face no issue:
Host: Windows
Zephir SHA1: ab15602
Board: nucleo_l476rg
Log console:

Button pressed at 790090416
Button pressed at 1221538460
Button pressed at 1221649043

Can you tell us more about your environment: host ? toolchain? ...
Can you also try on the same SHA1 than mine ?

[jasonedn]

Hi Alexandre, Thanks for your reply. I tried the same SHA1 as you but it didn't work either. My environments are as below. OS: Windows 10 Toolchains: /GNU Tools Arm Embedded/9 2019-q4-major The project was built successfully with west tool, as seen in the attachment build.log. The generated isr_tables.c is correct but it was not built into the image. the _sw_isr_tables still used the default values, so it jumped to the default spurious handler when the button was pressed. However from the logs, it reported The package name passed to `find_package_handle_standard_args` (PythonInterp) does not match the name of the calling package (Zephyr). Does this help? Regards Jason

@andrewboie, we're not able to reproduce the issue, maybe your knowledge of this part will be more efficient to solve this point?

[jasonedn]

After I uninstalled Visual Studio Community IDE and zephyr software from my computer, and then I re-installed zephyr software, it worked properly. It seems that it was caused by some improper settings of the VS software.
