Hi VIGENSH bALAJI,
About this question, I already reply you in your case.
Do you have sector 0? or begin with sector 0?
sector 0 =512B, address is : 0x0000 0000~ 0x0000 01ff;
sector n, address is: 512*(n)~((n+1)*512-1)
if n=32, then address is: 0x0000 4000 ~ 0x0000 41ff;

Wish it helps you!
Have a great day,
Jingjing
