Hi Everyone,
I am using MCB2470U LPC2478 evaluation board. i am trying to interface an 16 GB SDHC card using MCI mode but I am not getting any response from the SDHC card. But the code was working fine for old SD cards. I figured out that the code is only supports below 2.0 version SD cards and not supports for new version SD cards.
So, I am sending the commands which supports the higher version SD cards which are mentioned in flowchart in the SD 2.0 specification document. But still I am not getting any response from the card that I observed it in the Oscilloscope.
Is the LPC2478 MCI peripheral supports newer version SD cards ? If supports how to proceed further.
Thank you in advance.
Regards
Kranthi
