Sd Card Idle

Started by Akila.S October 7, 2010

     I am trying to initialize Transcend 1GB Micro SD Card for my
application. I am first initializing clock to KHz and then sending 80 clock
pulses by making chip select high(Chip select is Active low signal), then I
am making chip select low(Assert Chip Select) then sending Command0(0x40,
0x00, 0x00,0x00,0x00,0x95). But the response from the SD Card is 0x0000. It
is not being IDLE. It is showing busy. I am sending Command0 for 1 sec and
checking if each time the response fro the card is idle, if IDle to come
out of loop. Please let me know what's wrong. The Sd card is NOT IDLE.
