Configuration files for debugging Tricore Binaries with IDA 7.4 and TRACE32 Simulator

README

1. Install TRACE32 for Tricore from https://www.lauterbach.com/frames.html?download_demo.html
2. place ida.cmm into the TRACE32 installation folder
3. overwrite config.t32 found in the TRACE32 installation folder with the one provided
4. change the "SYS" variable of this config.t32 file to point to your TRACE32 install folder
5. edit %IDADIR%\cfg\gdb_arch.cfg as described in the provided "gdb_arch.cfg" file
6. open the file "demo.elf" from the TRACE32 installation folder with IDA
7. In IDA, go to "Debugger -> Select debugger", pick "Remote GDB debugger"
8. Go to "Debugger -> Debugger options -> Set specific options", tick the
   "Run a program..." checkbox, then click "choose a configuration" (which should fill
   the "command line" edit field) and confirm.
9. Go to "Debugger -> Process options...", fill the hostname (127.0.0.1) and port (30000)
   text fields
10. "Start process" (F9) or "Run to cursor" (F4) will start TRACE32 in the background and
    will allow the file loaded into IDA to be debugged using the TRACE32 simulator's GDB
    backend
