STM32 is actually a whole family of microcontrollers. In this context, likely a blue-pill board was meant (e.g. [1]). As mentioned, this requires more effort to set up. You need to solder the pin headers and you need another device to program a flashrom-compatible firmware[2] to it. For the programming, you need a TTL-level (3.3V!) UART. For instance, a USB adapter, or the UART of an RPi. There are also other STM32 boards that work with this firmware. But the blue-pill is the famous/cheap one. > > If a Raspberry Pi is used, is it both the second computer and the programmer > all > in one or is a second computer or a programmer still needed? It can act as the second computer, you just need a keyboard and screen I suppose. flashrom works well on the RPi. Usually you can just install it with your package manager.
