Yash,
Have you checked out the emFile component?
There are emFile examples available.
You need to make sure the emFile example you're going to use assigns the SPI pins you need to interface to your SDCard.
Note: Most SDCard boards can ONLY use a maximum of 3.3V as a power supply to its VDD. Most PSoC kit/eval boards default to 5V.
Some SDcard boards can take 5V as a supply but have a LDO to 3.3V and also include SPI signal level translators.
