Decode failed

[dbischoff777-zz]

Greetings!

Sadly i get the error "Decode failed". Arduino IDE is 1.85 and i'm using the latest Decoder release.

Update: Using the previous release 1.0.6 fixed the problem. Decoding was successful.

[JasXSL]

I can verify this, 1.0.6 works.

[jhmluna]

Also with me. Arduino IDE release 1.8.5 and Windows 10 64 bit does not work. Gives me Decode Failure error.

[PlastiBots]

Same for me per @jhmluna

[madmartin]

I never had a successful exception decode with release 1.1.0 on arduino 1.8.5 on linux-64bit.

BTW Release 1.0.6 DOES decode my exceptions, but points to meaningless filenames and line numbers.

What kind of information can I deliver to help find the problem? ESP 8266 core versions 2.3.0 and 2.4.1 tested, both the same result (decode failure)

[jackkum]

Downgrade to 1.0.6 fix this issue to me,

[madmartin]

@jackkum Are you sure? Does 1.0.6 decode your ESP's exceptions in a way that helps you? My experience is that 1.0.6 decodes linenumbers that do not exist in the file it is talking about, allover a bunch of useless messages. This should be a known issue with 1.0.6.

[jhmluna]

I realized that I was using the Arduino IDE installed by Windows Store. After uninstalling and using the installer provided by the Arduino website, put the xtensa-lx106-elf-gdb.exe file in the core package folder of ESP8266, started working.

[jackkum]

@madmartin Yes. First I downloaded the latest version, then I replaced xtensa-lx106-elf-gdb.exe file and I got an error Decode faild all the time. Then I downloaded the release 1.0.6, unpacked and replaced all the files and after that I got the human stack.

[madmartin]

@jackkum @jhmluna Your explanations are too short. I only understand you copied the debugger (xtensa-lx106-elf-gdb) from its original place to somewhere else. Can you please explain again more in detail, especially with directory names?

[jhmluna]

@madmartin

1. download ESP8266 Exception Decoder and install according to website guild. https://github.com/me-no-dev/EspExceptionDecoder

2. download ESP8266 SDK that includes "xtensa-lx106-elf-gdb.exe" file https://bintray.com/kireevco/generic/download_file?file_path=esp-alt-sdk-v1.5.0.258-windows-x86.zip

3. unzip esp-alt-sdk-v1.5.0.258-windows-x86.zip file and copy "xtensa-lx106-elf-gdb.exe" to following location C:\Users{user_id}\AppData\Local\Arduino15\packages\esp8266\tools\xtensa-lx106-elf-gcc\1.20.0-26-gb404fb9-2\bin

Release 1.0.6 on Arduino 1.8.10 on Ubuntu 18.04 decodes the stack trace with ?/?? at line numbers

[jbasiago]

I'm getting Decode Failed on Mac High Sierra with Release 1.0.6 and 1.1.0 on Arduino 1.8.12 using a NodeMCU1.0 device. Does this tool support applications that are divided into multiple files. I have a .h and .cpp file defined for each of 8 classes that I've developed for the application. It all compiles and runs fine, but I'm getting an exception under certain conditions. I'm getting no help with this tool. Any ideas?

Thanks,
