ST-LINK is STM's implementation of the | Serial Wire Debug (SWD) protocol. Think of it as JTAG if you're more comfortable with that.
ST-LINK is built into all(?) of STM's Nucleo and Discovery evaluation boards, which can be had for as little as US$10 from Mouser …
This page covers a few likely (hopefully unlikely) oh-noes.
You can upload new firmware through the bootloader. On power-up or reset,
the bootloader flashes the blue LED for 10 seconds. During that time, start

The current revision of the Alpha board is rev03.
rev01 was the board known as the 'dev-bridge'.
rev02 was functionally the same as the rev03, but in another form factor.
Develop a first, custom HSM board that can be used to support a first set of applications as well as being used for further development of new functionality as well as security mechanisms such as tamper detection and protection, key storage etc. Deadline is to …
