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
