FatFs halting sometimes
Update: Apparently this is a known bug, described on the Errata section of the ATSAM4L datasheet (pg.1192).    The bug (as described on the datasheet) is:   In...

Can't program fuses
Yes, I thought about that too. But it did seem to me more like a bug. And I even got scared when I searched online and saw a post saying that the AVRISP mkII can't program...

Can't program fuses
Well, erasing the device before setting the fuses did solve the problem. I truly didn't know that, specially since the fuses were set to FF / FF / FE / FF, and I was bring bits to...

XMEGA256 EEPROM issue
Well, in my case, rewritting of the EEPROM is not being done at anytime, so I don't think its getting corrupted because of a Vcc below the minimum for NVM rewrite. The EEPROM has...

XMEGA256 EEPROM issue
Well, the only relevant piece of code in this case is the one that maps the EEPROM into the SRAM:   ; Map EEPROM memory into SRAM address 0x1000-0x17FF for read (Pg.25)...

I/O's supplied by LCDA have no power
UPDATE: Problem is solved. I'll leave the solution here for the record: The ATSAM4L datasheet says on page 47: "When LCD feature is not used, VLCDIN must be always powered (1.8-3....

32MHz external oscillator
I did search on both the manual and the datasheet. But the one I have looks different from those images you posted. Maybe its an older version. But anyways, thanks for the info. I...

32MHz external oscillator
By the way, I'm still not finding anything like that on the ATXMEGA256D3 datasheet nor the manual. I looked all over the System Clock and Clock options section and did several...
