based on the work from https://github.com/me-no-dev/EspExceptionDecoder, I rewrote the decoder completely for command-line usage.

• works for me (I'm using Eclipse for ESP8266)
• not much tested
• no good error handling
• no documentation

Download the jar: https://github.com/littleyoda/EspStrackTraceDecoder/releases/latest

java -jar EspStackTraceDecoder.jar <Path to xtensa-lx106-elf-addr2line> <Elf-File> <Dump of Exception>

For a program created within eclipse, I use the following command-line: java -jar EspStackTraceDecoder.jar /home/XXXX/.arduino15/packages/esp8266/tools/xtensa-lx106-elf-gcc/1.20.0-26-gb404fb9-2/bin/xtensa-lx106-elf-addr2line /home/XXXX/project/Release/project.elf /tmp/dump.txt
