Working with raw memory

The memory command allows reading or writing raw memory in a debugged program.

Available commands: memory read <address> - reads an 8-byte block at the specified address in the debuggee’s memory memory write <address> <value> - writes an 8-byte value to the specified address. Note: values are written in little-endian byte order (the last byte of value is stored at the first byte of address).

Usage example

Consider this Rust program:

fn print_val(val: u32) {
    println!("val is {val}");
}

fn main() {
    let mut some_val = 3;
    some_val += 1;

    print_val(some_val);
}

Goal: Instead of printing 4, we'll manipulate a raw memory to force the output 5.
