DRM104 SD Card Reader

I see several people have been experimenting with the JM60 SD card reader App.  Has anyone got it to work?  On my DEMOJM60 it hangs during the SD card init.  I can see Data to the card and data from the card, but it eventually gets gets hung-up waiting for SPI data from the card.  Any ideas?

 

Thanks,

 

B.K.

Hi BK, 

did you set your set your SPCLK to 375kbps when init?

also u need to generate min 75 clk pulse b4 SS asserted and 16 after at un-asserted state follow by sending reset cmd and keep repeating this process until you see the idle bit = 0.

 

Regards,
