I'm trying to interface the lpc4337 with a micron 4GB eMMC card.
I'm able to initialize the card and get the CID and CSD values. (cmd0, cmd1, cmd2,cmd3)

I'm trying to get the ECSD data.
How can i get this data?

Another question i have is, when i send a cmd3 command i get a reponse of 0x500 in reponse register0.
According to the jedec documentation for jedec standard 84-a44a i should get a R1 response (48 bits).
But i am not getting 48 bits.

Can anybody help me?

Best Regards,
