Have you made sure that the switch on the SD card is not in the ''lock'' position? Really obvious suggestion, but it has happened to me before. Especially for SD slots that were moving the lock with some insertions.

hi again

the switch is not in the lock position.

thing is the board which i am using is having a SPI interface to the SD card. so if I use the SPI interface , will it work using the SDIO registers.

Plz reply.....

thanks in advance
