When our firmware is built with SwiftDecoder version 7.10.3 and 7.10.1, it crashes within 10 minutes at random time. When the firmware is built with 7.8.1 or 5.4.18, it runs over 48 hours without crashing.

The scanner is set up for continuously scanning and reading a 36 character Data Matrix code at fix position.

From our firmware, we didn't get any Exception or Assertion failure. It looks just like a watchdog timeout reset. I am wondering if somehow the SD_PROP_CALLBACK_PROGRESS function is not called frequent enough.

Do you have any suggestions?

We did make changes to the Data Matrix algorithms that could cause them to take longer.  If this is causing a timing problem where the progress callback functions are not called often enough, we can add additional calls to the progress callback function.  Would it be possible to get an image or two of the bar code you are testing so we can look at it here?

I attached 2 images here.

Thank you
