There’s currently a significant amount of confusion around the full extent of the GPIO hardware issue in the Raspberry Pi RP2350 microcontroller, with [Ian] over at [Dangerous Prototypes] of Bus ...
The Raspi makers offered prize money for successful attacks on protective functions of the RP2350 microcontroller, which they have now paid out four times.
Maybe treating the RP2350 A0 stepping as an ‘engineering sample’ is a good idea for the time being, with A3 (or B0) being the one you may want to use in actual production. In some ways this ...
Specifically, the RP2350 comes with a quartet of new security features, that Raspberry Pi was keen to highlight. These are Secure Boot, TrustZone, Redundancy Coprocessor (RCP), and Glitch Detectors.
