I checked the flash status register in FMI_EraseSector func.There is no problem in register but program doesn't run.Also when i called the FMI_EraseSector func if i debug(program runs step by step) there is no problem,program runs well.So i wait 500 ms in FMI_EraseSector func.It is not solution.

I wait help

Hi sword.

My str9 revision is D.

If i call erase sector command program go in infinite loop on PAbtHandler.I tried to take flash code to ram but it was not solution.

And when debug -run step by step- there is no problem.I wait 2s after erase sector command.

Wait help

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
