ESP8266 exception decoder

I'm trying to use the built in exception decoder.
When I get an exception with the stack trace shown in the serial output, pressing the '!' button shows very little detail in the output window:
Quote:
Failed to resolve hardware exception from the monitor text
Exception:Error:3 -> LoadStoreError: Attempt to read/write memory in a manner not supported by the hardware (for example, trying to read/write a byte to a memory area that only supports word accesses)


Using the Arduino exception decoder provides me with the decoded stack trace.

Thanks for the report.

Can you attach the full build output with the vMicro > Compiler Show Build Properties, and Verbose options Enabled so we can understand your environment more.

Also please attach the output from the Serial Window when the exception occurs and you press the '!' button, so we can investigate further.

Hi, files emailed.
It sometimes works, sometimes not.
I've emailed the files for when it hasn't worked.

Thanks for the detail, and the files.

Trying the provided output in the Serial monitor has worked in vMicro when I have attempted it, and not all errors thrown can be decoded in the same way.

Does the output provided always fail to decode in vMicro? (you can paste it into the serial monitor, then close and re-open it to try it out, provided the sketch is compiled for the right board)

(You can also click on the addresses in the decoded output to jump to the source file where they are available)

Still sometimes yes, sometimes no - and more no than yes. When it works it's great!

I tried the copy/paste but the same, no decoded trace. Always works in Arduino IDE though..

Thanks for the update.

We are still struggling to replicate this, would it be possible to attach another Serial Monitor output which never works in vMicro, and a screenshot of it working in the Arduino IDE?

Thanks again for the files and detail.  We have resolved the issue internally, and we will update shortly when the fixed version is available for download.

..almost!
The decode is working now which is great but the link back to the source isn't quite there - it looks like it's missing the drive letter - see attached screenshot.

Thanks for the update and detail, this is resolved in the latest release (21.06.06.21), and the local files can be clicked on to navigate to the line number where the error occurred as expected.
