Chapter 09 "Type safe manipulation" is out of date

[lbellomo]

I have some troubles running 09-registers/type-safe-manipulation and I notice that the middle part is outdated:

• the example use cargo run but this don't start gdb. This should be cargo embed.
• also run the cargo with no argument, targeting the src/main.rs. This should be the example/type-safe.rs
• and it looks like the gdb section switched chapters but didn't refresh, because it shows src/07-registers/src/main.rs multiple times (should be 09, and the example/type-safe.rs).
• finally I see something different at the start of gdb and not sure if I miss some breakpoints or is something else:

I run:

# on "src/09-registers"
cargo embed --example type-safe

# on another terminal:
gdb-multiarch ../../../target/thumbv7em-none-eabihf/debug/examples/type-safe
(gdb) target remote :1337
(gdb) set mem inaccessible-by-default off
(gdb) break type-safe.rs:12
Breakpoint 1 at 0x166: type-safe.rs:12. (2 locations)
(gdb) continue
Continuing.

Breakpoint 1.1, type_safe::__cortex_m_rt_main () at mdbook/src/09-registers/examples/type-safe.rs:12
12          p0.out.modify(|_, w| w.pin21().set_bit());
(gdb) print *p0
# the big output go here

From the example I don't have this part and i don't know what trigger the sigint or the breakpoint:

[...]
Program received signal SIGINT, Interrupt.
cortex_m_rt::DefaultPreInit () at src/lib.rs:1058
1058	pub unsafe extern "C" fn DefaultPreInit() {}
(gdb) continue
Continuing.

Breakpoint 1, registers::__cortex_m_rt_main_trampoline () at src/07-registers/src/main.rs:7
