ARM(32) Code Snippet debugging with GDB Lauterbach Trace32 Simulator
  1. Install TRACE32 demo/trial for ARM from https://www.lauterbach.com/frames.html?download_demo.html
  2. place ida_arm.cmm into the TRACE32 installation folder
  3. backup config.t32 and replace it with the one provided here
  4. change the "SYS" variable of this config.t32 file to point to your TRACE32 install folder
  5. In your IDA installation folder, find and add the contents of the file "gdb_arch.cfg" provided here, edit the path to TRACE32 in line one, save the file
  6. Run IDA, go to "Debugger -> Select debugger", pick "Remote GDB debugger"
  7. Go to "Debugger -> Debugger options -> Set specific options", tick the "Run a program..." checkbox, then click "Choose a configuration" and pick "TRACE32: ARM32"
  8. Confirm and close the dialog, go to "Debugger -> Process options...", insert a hostname (127.0.0.1) and port (30000)
  9. Use "Start process" (F9) or "Run to cursor" (F4) in order to start a debug session

IDA setup

Setting up remote GDB debugging for other CPUs using Lauterbach TRACE32 Simulators should work in the same/similar way.

currently supported GDB backends
