Target.... Device Fw Mismatch ((better))

JTAG relies on TCK (clock). If your debug probe’s clock is too high (e.g., 10MHz on a long 30cm cable), signal integrity fails, and the IDCODE is corrupted. Reduce TCK to 500kHz or 100kHz in your configuration file.

: You updated your computer's Proxmark3 tools but didn't re-flash the hardware with the new matching firmware. Wrong Platform target.... device fw mismatch
