I have interface SDHC card with SPI protocol.

If I initialize the card while debugging it worked right. 
But if initialize it without it then card don't get initialized.

What could be the problem, like some timing issues. I also added 10ms delay b/w spi initialization & card initialization but didn't work.

Its timeout when I send CMD55_APP_CMD & ACMD41_SEND_OP_COND command
