How should be formatted SD memory for example RDB1768cmsis2_usb_msc?

This example connects to the USB bus, but fails after 30 seconds.

I think that everything is properly connected, and I'm using a micro-SD memory 4GB (with SD adapter).

The program stops at the function: U8 SPISend(U8 outgoing)

    SELECT_CARD();
    LPC_SPI->SPDR = outgoing;
    while (!(LPC_SPI->SPSR & (1 << SPIF))); // Stop here!

Thanks for any help.

Probably SDHC is your problem, try good old SD (max 2GB) :eek:

This is an SD sample, therefore working with my own board and 2GB SD without problems, but refusing to work with my 8GB SDHC at SPISend() ;)

WOW! I found a 2GB (no SDHC), and it worked.
