Cutter with arm debugging

Question

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?

Answer 1

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.

• 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.

Select "Start emulation" from Debug menu.

Set breakpoints/step/continue as if debugging.

Option 2

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

Launch remote session for target ARM binary.

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

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

Target the remote debugger.

Set breakpoints/step/continue like normal.
