[BUG] ESP32C6 WIFI stop work after enable GPIO Interrupt

[FelipeMdeO]

Description / Steps to reproduce the issue

Hello All,

I am using esp32c6-devkitc. After enable SPI 2 in slave mode, WIFI feature stopped work.

Steps to reproduce:
1: Run esp32c6-devkitc wifi defconfig
2: Build and Flash, run in nuttx: wapi scan wlan0 - I will get wifi available list
3: Enable SPI2 peripheral and configure it as slave.
4: Run step 2 again, now no one wifi will be available

This is my nxdiag:

Hello All,

I changed the title because during investigation I was able to see that the issue is related enable GPIO interrupt when we are using wifi.

So, another way to reproduce is:

1: ./tools/configure.sh esp32c6-devkitc:wifi
2: make menuconfig
3: System Type -> Peripheral Support -> enable GPIO pin interrupts.
4: Test wapi scan wlan 0
it won't work.

@tmedicci did you see this issue before?

[acassis]

@tmedicci did you see this issue before? Any idea why GPIO interrupt enable is breaking WiFi?

I think we should remove the option to disable INT for GPIO, because all MCUs on NuttX support it by default.

[acassis]

@FelipeMdeO @tmedicci I confirmed the issue:

nsh> ls /dev
/dev:
 console
 espflash
 gpio0
 gpio1
 gpio2
 null
 random
 rtc0
 ttyS0
 zero
nsh> wapi scan wlan0
nsh>

Before enabling the GPIO INT the scan was working!

@fdcavalcanti could you please help to investigate this issue?

[tmedicci]

Hi @FelipeMdeO and @acassis , we will investigate it internally soon.

[tmedicci]

Hi @FelipeMdeO,

Can you please test using another version of the HAL, just set the following env variables before running the make command. For instance:

ESP_HAL_3RDPARTY_VERSION=eff2dab80ce352018159d7fe67c437e505e12f0a ESP_HAL_3RDPARTY_URL="[email protected]:tmedicci/esp-hal-3rdparty.git" make flash ESPTOOL_PORT=/dev/ttyUSB0

Just to let you know: I just reserved some CPU interrupts that are specific for some peripherals and this probably is the reason for this issue. I was able to make it work with this new HAL. If it works for you too, I'll create the PR. Please let me know.

Let me test it properly and I update you as soon as possible.

Hello @tmedicci,

Thank you for fix this behavior. I did some tests and all is good now. Let's open a PR.

Hello @tmedicci,

Alright, I just need to wait for the internal tests to pass and I will open it soon. Thanks for testing.
