- add intermediate-step solutions
- add more hints
- refactor exercise & text to have the same amount of work on all OSes
- add `usb` parser solutions
- make `dk-run` less silent
- rename rtic binaries (shorter names)
- link to the main svd2rust API docs
the rtt-target implementation is light on compiler fences so the compiler could
be doing unwanted reordering of memory operations. At least patch up a place
where these orderings may result in an observable change of behavior
and adjust puzzle-radio starter code accordingly
this reduces the chance of people using puzzle-radio with the wrong dongle
app (i.e. loopback); that would lead to them getting response different than
what's indicated in the text
I have also added the app name to the dongle / serial-term output:
``` text
deviceid=75fa82ad7588b3c7 channel=20 TxPower=+8dBm app=loopback.hex
```
