Hi all,

I want to write data from flash bank 0 to another sector which in bank 0 too, and my code is following:

__ramfunc void copy_data(void)

{

SCU_AHBPeriphClockConfig(__FMI, ENABLE);

SCU_AHBPeriphReset(__FMI, DISABLE);

FMI_WriteProtectionCmd(FMI_B0S7, DISABLE);

FMI_EraseSector(FMI_B0S7);

FMI_WaitForLastOperation(FMI_BANK_1);

}

all functions in copy_data function is using __ramfunc too.

But my program will dead when execute FMI_EraseSector function.

Does anyone know how to write data to the same flash bank ?

Hi sword ,

Thank you , now I can erase and write data to flash .

But now I have a another problem.

When I erase flash , my watchdog will timeout and reset.

The datasheet said that WDG timer cannot set to Timer mode by software.

So how can I disable watchdog when erasing flash ?

I set the maximum value of PR[7:0] and TV[15:0]

I only have PCLK and no RTC clock on my board.

How can I set the timeout more than 2 seconds ?

Because erasing 1 sector will use 0.8~0.9 second, if I can set the timeout more than 1.5 ~ 2 seconds , the problem can be solved.
