STM32 Tutorial #39 - Jump to Bootloader Revisited

In this video we revisit how to jump to the built-in system bootloader without using the boot0 pin. The earlier video was a bit naughty as it uses the stack space to store a flag during restart (stack space is NOT initialised during a reset). In this video we do it more elegantly.

This video is leading up to a future video implementing a custom bootloader from scratch as well as a relocated application.

Very cool, thanks for the videos and Happy New Year.
