ERROR: XTENSA-LX106-ELF-GDB.EXE NOT FOUND!

Development Tools IDE 1.x

Finally, I found a walk around to launch on Windows7(64bit) + arduino 1.8.5 IDE. Here is the steps and link.

  1. download ESP8266 Exception Decoder and install according to website guild.
    GitHub - me-no-dev/EspExceptionDecoder: Exception Stack Trace Decoder for ESP8266 and ESP32

  2. download ESP8266 SDK that includes "xtensa-lx106-elf-gdb.exe" file
    Service End for Bintray, JCenter, GoCenter, and ChartCenter | JFrog

  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

  4. google and download libwinpthread-1.dll (64bit) to C:\Windows\SysWOW64

  5. google and download libexpat-1.dll (64bit) to C:\Windows\SysWOW64

  6. restart arduino IDE:
    MENU bar: tool >> Esp Exception Decoder
    decoder will show up perfectly !
