| # armv4t |
| |
| An incredibly simple emulator to run elf binaries compiled with `arm-none-eabi-cc -march=armv4t`. |
| |
| This emulator isn't based off any particular system -- it's moreso just a test-bed for showing off various bits of `gdbstub` functionality. |
| |
| ## Usage |
| |
| Run `gdb-arm-none-eabi` (or alternatively, `gdb-multiarch`) from the `test_bin` directory to automatically connect to the emulator + load debug symbols for the emulated binary. |
| |
| This example can be run using: |
| |
| ```bash |
| cargo run --example armv4t --features=std |
| ``` |
| |
| **NOTE:** If debug symbols couldn't be loaded, try rebuilding `test.elf` locally (requires the `arm-none-eabi` toolchain to be installed), and recompiling the example. |
| |
| ### Unix Domain Sockets |
| |
| GDB versions since \~2018 support running a debugging session over Unix Domain Sockets (UDS). Debugging over UDS can feel much snappier than debugging over loopback TCP. |
| |
| Running the example with the `--uds` flag will bind the GdbStub to a socket at `/tmp/armv4t_gdb`. |
| |
| This feature is only supported on Unix-like systems. |
