I have been trying to get my wdt and started playing around with the fuses on my D20E17. I ticked "WDT-Always on" and ticked "WDT-Enabled" and since then I have been unable to program or even read the device signature of my micro.
I have 2 Atmel Ice's in front of me Ive been testing with on both Atmel 6.2 and 7. I also (just to try) pulled everything out and closed atmel studio, waited for 30 seconds and connected everything back as this usually fixes my issue. But this time my device just seems dead.
Is it possible that the wdt is resetting the chip before the ICE can even read the signature? I thought the SWD interface would've been outside of the application/fuse section of the micro (coming from AVR). As such it wouldn't have any issues at least reading the sigature?
Any suggestions would be super!
