Impossible to write EEPROM on XMEGA32E

Hello to all,

I cannot write EEPROM with program under, my array fin[x] declared in {$EEPROM} works like in RAM with nothing memorised, I used in the past the same process with ATMEGA but it not works with XMEGA32E, why ?
Thans for help !

Device = xmega32E5, VCC=3.3;
{ $BOOTRST $04000} {Reset Jump to $04000}

{$EEPROM}
var
fin: array[0..87] of byte;

{ Var Declarations }
{$IDATA}
var
rep,dep,s1,s2,derposi,sens: array[0..87] of byte;
posi,a,b,note,dist,v,vmid,idc: byte;

{--------------------------------------------------------------}
{--------------------------------------------------------------}
{ Main Program }
{$IDATA}

begin
for a:=0 to 87 do fin[a]:=200;endfor;

loop

endloop;

end Proxi.

Hello Rolf,

So thanks to solve soon !
Anyway, Eeprom external programming with E-lab programmer and PDI works fine, the problem is only with internal software writting...
I didn't try to write eeprom using directly NVM registers, did you try already ? does it works ok ?

@all,

problem fixed now.
There is an unexpected hardware bug in the XMegaE5 series.
Fixed now by a workaround.

Update available this evening.

Tested update this morning, but unfortunately Eeprom is always impossible to write from program.
Really I don't understand this bug from Atmel, I cannot believe that Atmel company sells this XMEGA32E with Eeprom writting impossible without any test before to put it on the market !
Very strange in my mind !
