SD Card for SOPC with Fat32

Altera_Forum · ‎02-09-2017

Hello,

I have a Cylone II board with a Micro SDCardon it. I would use a Fat32 formated Card und Quarts 9.0 SP2. Are there some IP Core forte SOPC builder to save some data (no Pictures) on this Card?

Thanks for your help.

The "Serial Peripheral Interface (SPI)" IP can give you low level access to and SD card. However, it's got no awareness of data structure - such as FAT32. If you want to store data in such a way as to be FAT32 compliant you'll have to look at doing so in software - and quite a lot of it.

Cheers,

Alex

Hello,

it is not easy. My SD-Card doesn't answer.

Can anybody help me how I can test my communication with the sd-card?

Thanks

Have you found this page (from the same site you had found)?

Pay attention to the Initialization Procedure for SPI Mode (assuming that's how you're trying to access your SD card). Have you put your SD card into SPI mode? I won't respond until you do.

Cheers,
