Cutter with arm debugging

I've been able to run the debugger inside Cutter (radare2) using my native host (x86_64) libraries when reversing a x86 binary. How would I do such a thing when trying to debug an arm binary? How can I get cutter to use the libc.so for arm instead of my native host so I can debug?

ENVIRONMENT

  • Cutter: Version 1.10.0, Using r2-4.1.1, Based on Qt 5.12.1 (GCC 7.4.0, 64 bit)
  • System: Ubuntu 18.04.3 LTS

SOLUTION

  • Note: As of Cutter v1.10.0 debugging is still in beta, therefore these results may vary and change over time.

debug_is_beta

  • Option 1: Utilize the emulation features of Cutter instead of debugging.
  • Option 2: Connect Cutter to a remote session.

EXAMPLE

Option 1

Open Cutter with target ARM binary and seek to main function.

seek_to_main

Select "Start emulation" from Debug menu.

debug_menu

Set breakpoints/step/continue as if debugging.

debug_like_normal

Option 2

Open Cutter with target ARM binary and seek to main function.

seek_to_main

Launch remote session for target ARM binary.

user@host:~$ qemu-arm -g 5000 test.x

Select "Connect to a remote debugger" from Debug menu.

debug_menu

Target the remote debugger.

remote_config

Set breakpoints/step/continue like normal.
