Is there away to access the system bootloader through something like a UART port?

I'm using a STM32 Nucleo F429ZI. I'm wondering if there's a way to access the system's bootloader (not an IAP bootloader) through one of the Nucleo's communication ports (e.g. a UART port), and if this requires any hardware connections like connectin...

Vbus is driven in mass storage mode.

This specifically relates to the same stm32l496 and the USB functionality, specifically creating mass storage mode. I used STMCubeMx to generate the configuration originally, and have since checked that against sample project provided by STM on githu...

STM32F4 alternate function mapping confusion

It is very confusing to me how pin multiplexer is explained in the datasheet, it doesnt help the matter when using .SVD file in the debugger as it is even more confusing.Lets start with the SVD file. In the debugger I can see AFRL showing AFRL0-AFRL7...
