[En-Nut-Discussion] Ethernut 3 PHAT MMC Card

[ml]

Hi,

i try to use the mmc-card with ethernut3d and e boards. 
i reprogramm the cpld and use the ftpserv from tutorial. 
devPhat0 and devNplMmc0 is registered and ok but the 
_open function doesn´t work.
i use some kinds of sd-cards old 16 MB up to new 2 GB etc. 
always the same problem. 

Wrote a little testprogramm and see that

    /* Read MBR. */
    if (MmCardReadOrVerify(ifc, 0, fcb->fcb_blkbuf, 0)) {

tries to get something from the card and at least (after ~30 sek)
stop´s and returns NUTEOF.

The MCLK Line shows some groups of 5 clocks again and again.

Is anyone here who run´s this with Eternut3 Rev E board with
npl30e cpld?  (qrynpl shows version 6) 

best regards 
martin ludwig
