Yes I've thought about getting Atmel's evaluation board, but unfortunately I have a time constraint and so I decided not to get one. Well instead, actually I'm testing some codes on Arduino Due using the Atmel Studio soon. As it uses a similar chip, I think it's also relevant this way.
For my custom board design I've always mentioned, I copied most stuffs (clock circuit, jtag, decoupling caps) from Atmel's evaluation board and Arduino Due schematics, and in addition to that, I double checked with this particular note called the Schematic Check List (http://www.atmel.com/Images/11061.pdf
). So currently I don't think there is a critical need to get Atmel's eval board.
But actually I am concerned about this particular information given inside the note. It's about the decoupling caps (page 3). It says: "Warning: At power-up VDDIO needs to reach 0.6V before VDDIN reaches 1.0V"
. How do I verify this? Will the chip be damaged if the warning isn't satisfied?
