Not Able to erase Sector 0 when using IAP in LPC2214

Mustafa Shaikh

Thanks Peter....... My Apology for not putting the

Code in proper format ......

I want to implement the functionality of IAP in LPC2214.... for testing purpose I have taken the sample code from keil..... C:\Keil\ARM\Flash\LPC_IAP_256...In this code I have tried to erase all the sector & write data . I am able to erase all the sectors & write the data successfully.......except sector 0 ? as I try to erase sector 0 and write some data on it ......... it erases all the sectors and not data has been written ? The sample code form keil is ......
As You can see in the main function, we have disable the Interrupt function .........

    No need to create new threads. It just creates confusion for people reading or answering - remember that Google and other people may not know that the threads are related, or that the discussion has moved to a new thread.

    But you still haven't read the text directly above the message input box. If you had, then your code would have looked like (assuming you did indent the code with spaces):

    #include <stdio.h>

int main(void) {
    printf("Hello world!\n");
    return 0;
}
