Watchdog issue on esp32-c3-devkitm-1

[brunofgc]

Hi there.

I'm facing an issue on my program. It hapens ramdomly. There is no pattern, or I didn't realise the pattern. It's working ok and suddenly the issue appears. You can see the issue description bellow:

E (6578683) task_wdt: Task watchdog got triggered. The following tasks did not reset the watchdog in time: E (6578683) task_wdt: - IDLE (CPU 0) E (6578683) task_wdt: Tasks currently running: E (6578683) task_wdt: CPU 0: wifi

Have you ever seen this before? Thank you in advance.

Hi @brunofgc ! What framework are you using? What task is running on CPU 1? Are you doing anything unusual with the Wi-Fi peripheral? Usually, such issues caused by user's main code which simply runs too long so that the idle talk doesn't get a chance to feed the watchdog.

[brunofgc]

Hi Valeros, thank you for your help. I'm sorry for the delay.

I'm using Arduino Framework on PlatformIO plus Visual Studio IDE. And ESP32-C3-RISC-V Processor ( https://www.espressif.com/en/products/socs/esp32-c3 )

This MCU Variant has only One CPU Core. Only the "CPU 0".

I tried my best to put vTaskDelay(1) (at least) on every while or for loops.

It works for a long period, but eventualy stops.

I'm not using anything very different. This firmware deals with Bluetooth Advertisements, Bluetooth Connections, and also MQTT Thru WiFi, but there are "Boolean flags" to prevent they run at same time.

Even if they're able to do it. I tested this before and the Processor was able to handle all those tasks together.

I have the main loop() and also a second thread.

Hi, do you know a solution for this?

[brunofgc]

I could manage to get the start of the issue:

As you can see, it refers to a file "rwble.c"

Maybe someone experienced on the diagnostic codes could better solve this problem:

[lucasromeiro]

@valeros @metcalf @rgl can help in this case?

[valeros]

First of all, I'd recommend trying the latest platform from the development branch as is has support for the latest Arduino v2.0.4.

[env:esp32-c3-devkitm-1]
platform = https://github.com/platformio/platform-espressif32.git
framework = arduino
board = esp32-c3-devkitm-1

If doesn't work with the latest dev-platform then try your project in the Arduino IDE. After that we'll be able to roughly locate where the issue might be.

[brunofgc]

Thank you @valeros, I was busy to reply or even try it. I'll do my best to try those tips and I'll be back to provide you the results.

[brunofgc]

Hi @valeros unfortunately I tried updating the platform, it becomes a bit more stable, but it keeps freezing out. I'll try the Arduino 2.0 platform and give you a feedback.

[brunofgc]

I also got a better working using a vTaskDelay(50) on the ending of the loop() (main task)

[brunofgc]

Unfortunately after doing the update, I got experiencing anther bug. On begining of the code, it freezes out and provide this status.

And start a loop of restarts

Rebooting...

Hi @valeros It seems that I could fix the "WiFi related issue". I'm not sure what was done to fix it. But I updated the platform as you mentioned, I'm using flags to prevent simultaneous BLE Scans and distributed yield() in some points of the code.

Now I'm getting another problem:

DIAG0 1000e1a0 DIAG1 10000000 BB DIAG0: 000a4604 BB DIAG1: c1002e02 BB DIAG2: 00000000 BB DIAG3: 8e89bed6 BB DIAG4: 00000000 BB DIAG5: 00000000 assert rwble.c 261, param 00020000 00000000

Maybe you know how to reach the rwble.c writer. It seems to be something in the lib itself. It happens random in time. Keeps hours working, and suddenly freeezes after printing that diagnostic text.

[valeros]

Hi @brunofgc ! Did you try your project in the Arduino IDE? Does it work there? Anyway, the Arduino framework is built on top of https://github.com/espressif/esp-idf, so this file should be there.

[brunofgc]

@valeros I didn't try it on Arduino IDE yet. It works fine, but eventualy stops with that issue. It seems to be another issue.

I'll try it on Arduino IDE.

[tablatronix]

Anyone have a working pio env? I cannot get my C3 devkit to to boot at all, same loops.

[Jason2866]

Issue is fixed. Use latest release. If it still does not work delete folder .platformio and Platformio will fetch the latest. This is needed since old reminents are left.

[tablatronix]

Bad flash mode in bootloader, wipe pio cache and platform as mentioned above
