Hi guys,

Why would I update the firmware using the IAP instead of the ICP?

I'm thinking about connecting an STM32F4 uController to a BeagleBone and I want to have the capability to update the firmware on the STM32F4 using an application on the BeagleBone. If I have the STM32F4 pins (BOOT0, BOOT1 and NRST) along with USART1 connected to the BeagleBone, can't I just write an application on BeagleBone which controls those pins and update the STM32F4 flash accordingly?
