I managed to get a few samples of ATSAML11D16A - probably the first Cortex-M23+TrustZone chip ever, and I plan to cook a mini dev kit up for it. Is there any specific things I should test for? Is there any suggestion on designing the dev kit?
What I have in mind for the dev kit is a small board breaking all signals except clocks and SWD out to a 0.6in DIP style package. The clock pins goes to matching crystals, the SWD pins goes to a debug connector, and throw in an onboard USB to serial converter for power and quick communication, a reset button and a MCU-controlled LED.
