Hi,

I am trying to read and write to a SD card that is connected to SSP. after this stage I will try to have File system support.
is there a sample or a library for LPCXpresso ?
the processor is lpc4357.

Hi,

Have you looked at the SDMMC example on LPCOpen ? That can be a starting point.

thank you for your response,
my processor is 4357, and IDE is Xpresso, my board is based on Keil board,
I have downloaded related LPCOpen examples, but SDMMC was based on SPIFI interface, and it works fine on my board,
but due to some reasons, I need to change the package of 4357 processor, so I won't be able to have nice SPIFI interface.
so I want to have SD card connected to spi interface (ssp1) .

Which example uses SPIFI interface for SDMMC? Could you please point to it?

LPC4357 has SD/MMC interface. Any reason you are not using this interface!
