Get stacktrace from firmware crash #50

Open tonilopezmr opened 5 years ago

tonilopezmr commented 5 years ago

Using EspStackTraceDecoder library you can decode the stack trace with the firmware .elf file, xtensa-lx106-elf-addr2line file, and a txt file with the stack trace we want to decode.

The xtensa-lx106-elf-addr2line file is located into the arduino15 folder on your computer, in a path similar to this one: .arduino15/packages/esp8266/tools/xtensa-lx106-elf-gcc/1.20.0-26-gb404fb9-2/bin/xtensa-lx106-elf-addr2line

Usage

java -jar EspStackTraceDecoder.jar xtensa-lx106-elf-addr2line firmware.elf dump.txt

Exception example:

>>>stack>>>
