Hi, 
I need the possibility for exception decoding and the addr2line functionality, too.
Is this part of the head version of visual micro? According to the Visual Studio 2017 Extensions and Update page, I've version 1810.4.0 installed. Anyway, there is no "!" when an exceptions occurs.

Regards
Andreas

Post the serial output you are seeing with the exception.

Please find the serial output. This is the first issue, it cannot followed up with a function in the serial monitor nor the Exception Decoder (this gives the message that it is not available for "arduino-esp32).

Regards,
Andreas

And this is a different problem, but with the same result in Visualmicro - VM doesn't give any additional information, and the Exception Decoder is not available, too.

It simply says "Not Supported on arduino-esp32".

I found some advice to rename the arduino-esp32 to esp32, tried different directories, etc. With these changes, compiling works fine (some paths needs to be adjusted), but EspExceptionDecoder still shows up with the same error message. (see e.g. here: https://github.com/me-no-dev/EspExceptionDecoder/issues/24)

When using the addr2line on the command line, everything is fine, but it's not that comfortable.

I'm not aware of how to get verbose messages from the exception decoder.

Thanks for your support!

Regards Andreas

Please switch on "vmicro>compiler>show build properties" and "vmicro>compiler>verbose" and post a .txt file (click reply to attach) or email to info[at]visualmicro.com along with a link to this thread.

Thanks

I can confirm that it works. This is for another exception because I could not reproduce the other one anymore.

What I'm missing are some more information on the source code file and linenumbers. 

Output currently is:
Code
Select All
Error
   : ?? ??:0
   0x40080000 _iram_start
   :?:::0x400802e4:_NMIExceptionVector
   0x401be6cf __cxxabiv1
   0x40097010 invoke_abort
   0x40097213 abort
   0x401be716 std
   0x401ac17b __cxa_throw
   0x400da941 BLEClient
   0x400d1b27 connectToServer(BLEAddress)
   0x400d2435 loop()
:17 (discriminator 1):::0x401c628c:loopTask(void*)

Does visual micro show the "I" icon and then show a clickable stack trace?

Yes, the "!" shows a clickable list (not easy to see that's clickable) and if I double-click it jumps to the correct code line.

The stack trace reads like this
Code
Select All
Error
   : ?? ??:0
   : ?? ??:0
   : ?? ??:0
   0x400d26ff setup()
   : ?? ??:0
   : ?? ??:0
   :17 (discriminator 1):::0x401a1c54:loopTask(void*)
   :355 (discriminator 1):::0x40092815:vPortTaskWrapper


For the updated arduino-esp32 (1.0.1rc1 I used) the arduino Exception decoder works again for me. The results are

Code
Select All
PC: 0x400d26ff: setup() at C:\Users\AKAEM\Documents\Visual Studio 2017\Projects\disPOD\disPOD/disPOD.ino line 616
EXCVADDR: 0x801a1c57

Decoding stack results
0x400d26ff: setup() at C:\Users\AKAEM\Documents\Visual Studio 2017\Projects\disPOD\disPOD/disPOD.ino line 616
0x401a1c54: loopTask(void*) at C:\Users\AKAEM\Documents\Arduino\hardware\espressif\esp32\cores\esp32\main.cpp line 17
0x40092815: vPortTaskWrapper at /Users/ficeto/Desktop/ESP32/ESP32/esp-idf-public/components/freertos/port.c line 143


For convenience it would be great to extend the exception decoding in VisulMicro to give complete path/file name and line number directly, and to print et least PC (or did I miss something?)
