I'm working on a custom SAME54 board, using Atmel Studio and ICE programmer.
Atmel Studio is V 7.0.1931
ICE has firmware version 1.27
On one of my boards everything seems to work fine.
However, on another board, I'm seeing a very strange thing. Using Atmel Studio's Tools, Device Programming:
- On Memories page I do a chip erase
- On Fuses page, I just keep doing reads and looking at the fuse registers
- The output window says all lines are ...OK
But, values for SW0_WORD_0, TEMP_LOG_WORD_0 change once in a while.
Is this a sign of power problem? Or my SAME54 is broken?
My other board doesn't do this - the registers stay constant.
Any suggestions appreciated.
