Disassembly process?

[scotthauck]

Any suggestions on how to get a disassembly of code for ESP32 under Arduino? Specifically:
(1) Any pointers to a disassembler that people like? I'm developing on a Windows 10 box.
(2) Any pointers to where the executables are stored when you are using the Arduino IDE?

Thanks in advance.

Well, I at least found the object files.

C:\Documents and Settings\<user name>\Local Settings\Temp\arduino_build_<a number for that build>\sketch

Looks like it is time to install the ESP tools and figure out how to use objdump...

Got disassembly going, via objdump, on my Windows 10 box for Arduino compiles. Hope this helps other folks.

• Install the ESP-IDF tools (if you haven't already). See the homepage for how.
• Find the place where the Arduino tools do the build:
  https://www.kanda.com/blog/microcontrol ... -binaries/
  I'd suggest following the directions there to force the builds to an easily accessible folder.
• Open up a command window (I used the mingw32.exe within the msys32 installed with ESP-IDF).
• Navigate to the sketch subdirectory of the build you are interested in.
• Run objdump, redirecting the output to a file:
  xtensa-esp32-elf-objdump -S -d *.o > DISASSEMBLY.txt
