Proxmark3 Troubles

Updating the firmware now. Waiting for it to compile. I’d forgotten how, so I’m refining my notes, which might become a short guide for linux users. (Really mostly just your guide but without the Windows specific stuff.)

Okay, flashed. Launching…

Comparing that with what I had before… Yeah, looks like I didn’t have the right version before. Target.... PM3 GENERIC. (Not to mention it was three years old.)

Alright, checking the tuning…

[+] 13.56 MHz.............  5.08 V

[+] Approx. Q factor measurement
[+] Peak voltage.......... 1.5
[+] HF antenna ( ok )

Looks good. Will play with it a bit to see if it works better now.

Also, it’s been such a long time I don’t remember the last time I compiled the repo, but it seems that I installed it because I have pm3 and the related scripts in my $PATH under /user/local/bin. (No idea where my old clone of the repo is located.) I assume that compiling alone didn’t update those scripts, so I’m running the copy of pm3 from within the repo for now. I’m assuming that the optional install step of sudo make install would overwrite the outdated scripts in /user/local/bin?

Alright, taking it for a test drive.
