Embedded Rust: running an embassy example on a STM32F411 microcontroller

Getting embassy started on a STM32F411 (my device is one of www.aliexpress.com/w/wholesale-stm32f411.html?Sear…)

Timing-wise I managed to try to make this video exactly when there seems to be a defmt/probe-run and embassy incompatibility, so I show how I tried and eventually solved that one.
