I did not noticed If programming was successful, I found out after programming that the device did not configure ( via epcs64 and quartus 9.0).

But my problem is now that the normal boundary scan test passed before programming the device , did some ddr ram test with boundary sacn ,all ok.

Then I came to the conclusion that I was using the wrong programming file and used Quartus 9.0 to erase the epcs64 .

After this erase : I can not use the EP2S60 anymore, not with the USB blaster , not with the standard boaundary scan tools . I looks like the TAP controller is not working any more.

I thought it was board dependend but when I tried this on the second board with a EP2S60 : the same problem after the erase . TAP is not working !!

Am I the first with this problem ?

Tnx Hans
