Hi Nirmesh,

As mentioned in the earlier comment, the specific error message "GPIO isr service already installed" is indeed an error and appropriate changes would be done either in the GPIO driver and/or the button component to handle or prevent this error. It is harmless only in this particular context since we know what is causing.

W.r.t the watchdog issue you are seeing, I tried copying the new snippet into your original code from here and made some other minor changes in app_priv.h and app_main.c to compile it. The firmware worked fine for me as below

Code: Select all

I (882) gpio: GPIO[17]| InputEn: 1| OutputEn: 0| OpenDrain: 0| Pullup: 1| Pulldown: 0| Intr:3 
E (882) gpio: gpio_install_isr_service(449): GPIO isr service already installed
I (892) gpio: GPIO[18]| InputEn: 1| OutputEn: 0| OpenDrain: 0| Pullup: 1| Pulldown: 0| Intr:3 
E (902) gpio: gpio_install_isr_service(449): GPIO isr service already installed
I (912) gpio: GPIO[19]| InputEn: 1| OutputEn: 0| OpenDrain: 0| Pullup: 1| Pulldown: 0| Intr:3 
E (922) gpio: gpio_install_isr_service(449): GPIO isr service already installed
I (932) gpio: GPIO[21]| InputEn: 1| OutputEn: 0| OpenDrain: 0| Pullup: 1| Pulldown: 0| Intr:3 
I (942) gpio: GPIO[14]| InputEn: 0| OutputEn: 1| OpenDrain: 0| Pullup: 1| Pulldown: 0| Intr:0 
I (952) gpio: GPIO[25]| InputEn: 0| OutputEn: 1| OpenDrain: 0| Pullup: 1| Pulldown: 0| Intr:0 
I (952) gpio: GPIO[26]| InputEn: 0| OutputEn: 1| OpenDrain: 0| Pullup: 1| Pulldown: 0| Intr:0 
I (962) gpio: GPIO[27]| InputEn: 0| OutputEn: 1| OpenDrain: 0| Pullup: 1| Pulldown: 0| Intr:0 
I (1022) wifi:wifi driver task: 3ffd0274, prio:23, stack:6656, core=0

I (1052) wifi:Init management short buffer num: 32
I (1062) wifi:Init dynamic tx buffer num: 32
I (1062) wifi:Init static rx buffer size: 1600
I (1062) wifi:Init static rx buffer num: 10
I (1072) wifi:Init dynamic rx buffer num: 32

From your logs, we see that the main task is using up the CPU whereas for me, it just proceeded without issues. So it seems there is could be some difference between our environments or the application code. Can you share the following?

1. esp-idf version (Using "git describe" command)
2. Platform used (esp32, esp32s2, esp32c3 ?)
3. Development Board (This should not matter much, but just in case)
4. The application code (you may just update your github repo)
5. Your project's sdkconfig file

Hi Piyush,

Thanks for your effort in trying to reproduce the issue.

So As per your log, I am seeing GPIO isr error messages but it is not causing any Watchdog reset issue with 4 switches at your end.
I go through the button component and suspecting these error is due to this gpio_install_isr_service(0) call.

I am sharing the details for further debugging.

1. esp-idf version (Using "git describe" command)
>> v4.2.1

2. Platform used (esp32, esp32s2, esp32c3 ?)
>>esp32

3. Development Board (This should not matter much, but just in case)
>> custom board based on ES32 WOORM

4. The application code (you may just update your github repo)
>>updated Github repo with 4 switches.

5. Your project's sdkconfig file
>>attached project SDKconfig file.

Hi Piyush,

As you mentioned, you did a small change in the code and it is working fine for you. may I know what change you have made in this example?

Thanks,
Nirmesh

Hi Nirmesh,

I tried your new code from github and compiled it with idf 4.2.1. I only did this minor change for it to compile with latest esp-rainmaker:

I see the errors, but not the crash.

Hi Piyush,

I uploaded your binary on my board and the device got crash and rebooting in a loop.

I checked all the switch input pins and found the issue because of GPIO Pin 18 and 19 so I changed these pins to some other gpio pins.
Now it is working fine.

Thanks,
Nirmesh

"E (906)" indicates it's an error message.
If it is indeed harmless, please convert it to warning message (W).
Fyi, this is indeed an error, caused by a few of our components not working well together. The message you see is the only result of this error, as the GPIO API happens to catch it, but even if it is otherwise harmless, it is an error regardless and we will take measures to fix it.
I don't find the fix in any branch, did I miss something?

For anyone else having the same issue, mine was due to me calling gpio_install_isr_service multiple times since I put it in my interrupt pin initialization function.

(I'd like to also state that in general, it's not really our policy to generate error messages like that that you can 'just ignore', even if it happens to work out here.)
Actually, if you notice "Error:GPIO isr service already installed", it usually
means you have at least 2 components calling gpio_install_isr_service().
Such component usually has a gpio_uninstall_isr_service() in deinit.
Which means if a component calls the deinit(), the other componet stop working.

esp_camera is an example that will call gpio_uninstall_isr_service() when deinit and this may cause problems.
