Hi,

     I want to display 2 parameters(ID and BD) value on seven segment display. The values will be dynamically changed, so every time I want to write these 2 byte of values on FLASH memory and every power ON or System Reset, I want to Read that values from Flash Memory.

    Before writing any values if i read the Flash memory, I'm getting some garbage values. After erasing and writing 2 bytes of values to Flash memory, I am not able to read that again. Can anybody help me....

Thanks

Selva.

Thanks for all your response....I got the solution.

Actually I'm using Flash memory of 128KB, and the flash region is 0x08000000 - 0x0801FFFF
