Watchdog triggered when testing 'micro_speech' sample on ESP-IDF v5.1 #54

Open misterb0407 opened 1 year ago

misterb0407 commented 1 year ago

Steps:

  1. cd to root of project files (not examples/micro_speech) so that 'component folder is recognized by system

  2. Build the sample under 'micro_speech' examples by using docker ESP-IDF version 5.2 $docker run --rm -v $PWD:/project -w /project -it espressif/idf:release-v5.1 Then inside the docker prompt: $ idf.py build

  3. Then flash and monitor, you would see the following in the log: `E (434939) task_wdt: Task watchdog got triggered. The following tasks/users did not reset the watchdog in time: E (434939) task_wdt: - IDLE (CPU 0) E (434939) task_wdt: Tasks currently running: E (434939) task_wdt: CPU 0: tensorflow E (434939) task_wdt: CPU 1: IDLE E (434939) task_wdt: Print CPU 0 (current core) backtrace

This was not observed when building the same code with ESP-IDF version release-v4.4

@misterb0407 is the target esp32 in both the setups?

misterb0407 commented 1 year ago

Hi @vikramdattu , yes , the target was esp32 for both setup. As a work around I just disable watchdog for now from the idf.py menuconfig

vikramdattu commented 1 year ago

@misterb0407 okay, thanks! I will certainly check for newer IDF branch and update you on the same.

@misterb0407 I saw your issue on IDF: https://github.com/espressif/esp-idf/issues/11678 Does having that particular change for I2S setup help with this example?

misterb0407 commented 1 year ago

Hi @vikramdattu , it is hard to say as the example here uses legacy I2S driver but the https://github.com/espressif/esp-idf/issues/11678 uses the new I2S driver. Do you have any config (in this legacy driver) you would like me to try?
