    Hi all...

    I write a bootloader, it occupies at bank1, takes application from uart and write bank0.I wrote problems to forum on various stages.Anyway I encounter a new problem.

    When i was bank1, tried to write to bank0.But my application crashed.

    First i did

    SCU_AHBPeriphClockConfig(__FMI, ENABLE);

    SCU_AHBPeriphReset(__FMI, DISABLE);

    and in the startup.s

    FMICLK = RCLK/2

    If i enable fmi clk and disable reset application doesn't run?

    What can i do for this problem.

    Regards...

    Mehmet

    Same issue I am facing, with PLL and RCLK set to 96MHz and FMICLK configured to 48MHZ (RCLK/2), I see the microcontroller crashing and gets hanged up. I could bring it back to life only after a System Reset/Power Cycle.

    Microcontroller used : STR912FAW46x6.

    Crystal : 12MHz
