+//! Note that when you reach this point OpenOCD will become unresponsive and you'll have to kill it
+//! and start a new OpenOCD process before you can invoke `xargo run` / start GDB.
+//!
+//! Cause: You uncommented the `monitor tpiu ..` line in `.gdbinit` and are using a named pipe to
+//! receive the ITM data (i.e. you ran `mkfifo itm.fifo`). This error occurs when `itmdump -f
+//! itm.fifo` (or equivalent, e.g. `cat itm.fifo`) is not running.
+//!
+//! Solution: Run `itmdump -f itm.fifo` (or equivalently `cat itm.fifo`) *before* invoking `xargo
+//! run` / starting GDB. Note that sometimes `itmdump` will exit when the GDB session ends. In that
+//! case you'll have to run `itmdump` before you start the next GDB session.
+//!
+//! Alternative solution: Use a plain text file instead of a named pipe. In this scenario you omit
+//! the `mkfifo itm.dump` command. You can use `itmdump`'s *follow* mode (-F) to get named pipe like
+//! output.
