I have problem with programming UC3C device (AT32UC3C0512CAU). I'm using Atmel-ICE programmer and Atmel Studion 7. When I attempt to program the memory I get following message:
Timestamp: 2017-04-10 15:05:03.336
ModuleName: TCF command: Modules:writeToMemory failed.
Failed to write segment at 0x80000000 to target for memorytype base
When I tried to change fuses I got following mesage:
Starting operation write registers
Writing register FGPFRLO...OK
Writing register USERPAGE_WORD_0...OK
Starting operation verify registers
Verify register FGPFRLO...Failed!
Verify register USERPAGE_WORD_0...Failed!
Verify registers ... Cancelled
Annoying thing is, this design is a copy-paste from previous hardware version, which works perfectly fine.
I checked voltages - 3.3V at peripherials, 1.8V at core (checked at pin 55).
I would appreciate any ideas how to solve this problem.
