    Hello sword,

    So thanks for your answer.

    I can boot from bank1 but can't erase sector.

    I have remapped physically the banks.But i have not used caps.I used

    Keil v3.05.Bank1 is at 0x00 address.

    In the startup file i have changed the initialization of the banks mapping as it place bank1 at 0x0, and bank0 at 0x8000.

    In the file flash.h(i don't use st library) i decommented the line #define Remap_Bank_1.

    In program all the functions from the flash.c run from SRAM.

    I can boot bank1 and write ban0.I checked, it is right.But when i call eraseSector(B0S0) func(erase sector 0 of bank 0) program go in PAbt_Handler for infinite loop.

    But when i debug (step by step run) i can erase.

    So thanks again, i wait your help.

    Best regards..

    Hello sword,

    I did everythings that you said but problem keeps on.

    But a good thing have happened; when i closed timer int. i could erase sector.

    How does timer int. create flash problem?

    Mabe my library has a bug.

    I sent you required files.If you check i will be so glad you.

    If you send me your e-mail address i sent you project-sory the library does not belong to me-

    regards

    mehmet
