Your email   CMD55 assumed to be nonexistent for MMC Type BUG Status CLOSED MMC and SD card are discerned after CMD55. (@ line 529, spi_boot.vhd) According to SD card Physical Layer Simplified Specification Version 2.00(Downloadable @ sdcard.org), CMD55 is a "prefix" to ACMDs, and the judgement should be made after ACMD41 I think. (Figure 7.2) Please check it out because the code may not be tested on MMC card.   Stats Nobody is monitoring this item Progress   Submited date 29-Jul-2007 Submited by dan0529@1...   Assigned date 18-Aug-2007 Assigned to Arnim Laeuger   Closed date 18-Aug-2007 Closed by Arnim Laeuger Comments by Arnim Laeuger on 18-Aug-2007 Released as part of Version 3.2, rev.
