Reset STM32(F4) to particular startup address

Hi,

I have partitionned my STM32F4 memory into 2 parts :

1 part, starting from the default startup address ( 0x8000004 ), and 1 part starting from a custom startup address ( 0x8004004).

When running code from the 2nd part, I would like to RESET the STM32, but restart at my custom startup address instead of the default one.

Is there any special way to achieve this ?

Thanks.

Best regards,

Vincent.

The hardware doesn't support that.

Use a magic value in ram and have the reset handler in the loader recognize that and immediately transfer control to the application.
