Hi, I'm trying to communicate with a SD card on MCI bus. I've implemented the structure of software released by NXP site (LPC23xx_24xxSampleSoftware.r5) to build my commands. When I send a comand to the card I've controlled the signals with my oscilloscope and I find them correct but the card doesn't answer. Have you got any suggestion to me? Have you got any simple piece of software that configure the card and send a command correctly? The amazing aspect for me is that the electrical signals are correct, so I don't know what to do to solve this problem...
Thanks and bye
