We&#39;re running out of time to plant though, so I need to get it fixed asap.</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> Nice.</p><p>Have we ever talked about the horrible perversion of JTAG I implemented for debugging my thesis system? This kinda reminds me of it</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> wheeeeeeeee at least it’s the CPU that’s broken, and not the debugger that scribbles garbage over register a0 (first function argument) during single-step use. Makes memcpy() do interesting* things…</p>

I resolved that they must be names rather than numbers. This here is Mr. Onepointfiveinches Smith.</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@Viss" class="u-url mention">@<span>Viss</span></a></span> to clarify, they took Signal, which is E2E encrypted and doesn&#39;t store message on the server, and deliberately modified it to just send everything to this third-party &quot;vendor&quot; in plain text. I wonder if that was malicious or just dumb, and how this thing ended up being used by what appears to be half the government.</p>

<p>the advantage of the implementation strategy I picked is that the entire read is done in one long burst without requiring more than a single USB roundtrip; as a result, it occurs at the maximum speed the JTAG interface can provide</p><p>(nobody cares about ARM7TDMI, but the technique generalizes to CoreSight, and will be even faster there)</p>

<p>in the upcoming <a href="https://mastodon.social/tags/GlasgowInterfaceExplorer" class="mention hashtag" rel="tag">#<span>GlasgowInterfaceExplorer</span></a> ARM7TDMI debugger, here is how you can read system memory using just a few lines of Python</p><p>this avoids the need for any existing interface like GDB server as it lets you easily manipulate CPU state in every feasible way</p>
