Hello Nico,

Is a Raspberry Pi with keyboard, screen and jumper wires and a programming clip enough hardware to flash the ROM to the chip of my ThinkPad or is anything else necessary?

Regards,

Bernd

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.

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.
