I want to communicate with a Mutimedia Card using the SPI interface of my processor MC9S12E64.
When i send a CMD0 for setting the MMC to the SPI mode, i get the correct answer (0x01) from the MMC. But when i send the CMD1 to the MMC for startting the initialisation of the MMC, i get also 0x01 us answer, it must be a zero.
Is there any application note by Freescale talking about the MMC?
Has anybody an example code for this aplication?
Think you for your fats reaction.
