interfacing issues of SD-card with LPC 2468

i interfaced NOR flash, SD-RAM with LPC 2468 with its EMC state meachine reference.

similarly, i want to interface SD-card with 2468. but due to EMC SD-card detection process is failed, if i disable EMC operation SD-card is properly interfaced.

is there any issue with EMC operations on SD-card interfacing?

No, but you might want to consider changing SD card brand. That can help, or increase the DMA transfer timeout. See LPC24xxMCI.h (not sure about the name).
