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:
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.
