I needed an example device for tests of an implementation of a serial connection terminal. A Raspberry Pi is especially suited: It dumps a lot of kernel data upon boot and it listens for input as soon as the login prompt appears (after about one minute).
Required:
- FTDI serial cable to USB converter TTL-232R-3V3 from http://www.ftdichip.com/
- Raspberry Pi
- Jump wires male - female
Wiring is simple: Just connect the FTDI cable as shown in the sketch below:
- FTDI GND -> RaspPi GND
- FTDI TXD -> RaspPi RXD
- FTDI RXD -> RaspPi TXD
- Fire up PuTTY and setup as in the following screenshot (speed/baud rate = 115200)
- Press "Open" and you should receive the kernel boot messages followed by a login prompt.
