Hi all, I've been facing RTT issues on my target, and I've tried to spend some time now to find a solution (JLinkRTTViewer works just fine). For the first time, I've been able to get RTT to work with this hack:

```diff
diff --git a/probe-rs/src/probe/arm_debug_interface.rs b/probe-rs/src/probe/arm_debug_interface.rs

```

... buf it takes sooo long, making it unusable in practice. The error I'm facing is:

```

```

Any help/guidance would be appreciated.
