## Week 2
Hello, World - Debugging and Hacking Basics: Debugging and Hacking a Basic Program for the Pico 2
### Exercise 2: Use a Different SRAM Address
### Non-Credit Practice Exercise 2: Use a Different SRAM Address
#### Objective
Practice writing to an alternate SRAM location and redirecting `r0` so your message prints from `0x20001000` instead of `0x20000000`.
#### Prerequisites
- Raspberry Pi Pico 2 with debug probe connected
- OpenOCD, `arm-none-eabi-gdb`, and a serial monitor ready (Week 2 steps 0a–0e complete)
- OpenOCD, `arm-none-eabi-gdb`, and a serial monitor ready (Week 2 steps 0a–0e complete)
- `build\0x0001_hello-world.elf` flashed and running
- Comfortable setting breakpoints at `0x1000023c`
