Using AudioAnalyzeToneDetect crash up Teensy

[digitalwire]

I play a WAV file from Teensy SD card to decode morse signals via the audio lib. For this I use AudioAnalyzeToneDetect. I call the function every 5ms. After a few seconds teensy hangs up and emits a humming sound, a few seconds later teensy is restarted by the internal watchdog.

How can I find out the reason for the crash?
At what time interval can AudioAnalyzeToneDetect be called?

You can use CrashReport. See details here.

On Windows Addr2line can be found here: "C:\Program Files (x86)\Arduino\hardware\tools\arm\bin\arm-none-eabi-addr2line.exe"

Here you can find some more useful info on using CrashReport and Addr2Line.

True, but only if using Arduino IDE 1.8.19.

Arduino IDE 2.3.3 installs it somewhere inside %LocalAppData%

Ok, let me check this out next weekend.

You can check the entry in the unofficial Teensy wiki <here> for links to descriptions of where to find the addr2line utility for both the old (1.8.x) & new (2.3.x) Arduino IDE, as well as detailed descriptions of how to use it.

Hope that helps . . .

Hhmm, I found the following

CrashReport:
  A problem occurred at (system time) 0:26:25
  Code was executing from address 0xF442
  CFSR: 1000000
        (UNALIGNED) Unaligned access UsageFault
  Temperature inside the chip was 48.79 °C
  Startup CPU clock speed is 600MHz
  Reboot was caused by auto reboot after fault or bad interrupt detected

addr2line report this

C:\Users\<snip>\hardware\avr\1.59.0\cores\teensy4/AudioStream.cpp:164

The crash occures when the first WAV file has played and I choose a different one and start to play.
I use the serial for the Nextion display at the same time to show the decoded characters on it
Maybe a different approach is needed using this audio library?
