DDR2 HPCII v11.0 problem, thanks for help !

everything seems well, however, local_init_done is always low, what's wrong? I tried both the full calibration and "skip the calibration", it doesn't change anything, the local_init_done is alway...

Please see attached. This is Altera example driver with ALTMEMPHY for DDR2 memory

Even with "Skip Calibration" it never ends. It ran all night and only reached 12ms. Look at the result. It only wrote 0x00 and 0xFF in the begining, and then DQ and DQS were inactive for the rest. Test Complete never went high. What is it waiting for?

Does this give anybody any clue? I must be doing something very basic wrong
