hello all,

This question is about interfacing an SD memory card with LPC1769 xpresso board. Im using chan's fatfs library.

   When the SD card is connected (to the socket) before power up the board, the disk_initalize() function return an error(1) in debugging mode. Then without removing power I reconnected the SD card to the socket, and disk_init recognized the card. I am using all SPI lines (not card detect), and double checked their connections. What i dd wrng ? luking 4 ur quick replies.
    
Thanx

If you look for my previous posts I posted working code(tested) 1769 interfaced  with SD card(I vaguely recall it was SSP0).
