Programming Flash in STM32F407

First, let me just say that I am new to the STM32 series of microcontrollers, so if I am asking the obvious, or has already answered somewhere else, I apologize.


Now, I want to use a bank of STM32F407s as co-processors for a bigger computer system. To this effect, I need to download firmware to the STM32s from the main CPU over and over again. I know I can do this using the bootloader in the STM32's system memory, but I am worried that it will not be able to recover, should the system memory gets corrupted.


So, I would love to program my code directly into the STM32's flash memory using JTAG or something similar, without going through software running on the chip. There is a lot of info about how to do this on the STM8 family, but nothing on the STM32.


How can I do that?
