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;

Thank you Jing,

1)That means Flash Memory is Continuous and there are no reserved memory inbetween???

2)I can Use anything From 0x00000000 to 0x00001FFF??? Divided into 256 Sectors with no reservations?

Hi Vignesh balaji,

1) Flash memory is continuous, normally, user can use the last flash sector as the user area, the above address will be used for the code.

2)No, use the last flash area as I suggest you, the beginning of the flash will put the interrupt vector and the flash chip configuration filed and the code.

Wish it helps you!


Have a great day,
