Blackfin BF537 Micro SD via SPI

Hi Markus,

 

Still not having much luck improving my code.  I was wondering if you could answer one more question for me though - are you using the automatic Chip Select line provided by the Blackfin VIs?  When I use this, my chip select line (active low) bounces high between every 8-bits.  I've read some documentation that states that the CS line must be low for the entire transaction, so I'm wondering if this could be causing some of my problems.  What are you doing to prevent this?

 

Thank you,

Jason

Hello Markus,

 

Would you mind reposting your SD card vi (it is no longer available)?  I'm trying to get one of the ARM kits to access a microSD via SPI.

 

Thanks in advance!

 

Regards,

Adam

Hi .... I would like to know if it is posible writes data in SD card from a FPGA not with a host I want that the application works stand-alone.... There is toolkits with SPI and I2C to manage digital buses and protocols....Is posible to save data in the FPGA...without a host?
