Enter System Command Line via Debug serial port

The NanoPC-T1 expand the debug serial port with TTL level, if you want to use it, you can use the Debug Adapter board to connect to the PC.

We provide the TTL to RS232 adapter board on our online shop, you can buy it from us, it need Cross serial Cable too.

To use the TTL to RS232 Serial board, you need a terminal emulator program that is an utility that can send and receive characters via a serial port.

Connect the Debug serial adapter to the Debug Port with 4Pin cable, then connect the TTL to RS232 Adapter board to the PC by Cross Serial cable.

Serial terminal emulator on Windows PC

By default Windows provide an utility called HyperTerminal that is usable with USB serial cable but we suggest to install a free utility called putty because it can works also as a SSH remote terminal .

It doesn't need to be installed, just download and run it, if you can't download it, send mail to use.

At startup you have to specify:

  • Connection type: Serial
  • Serial line: COMx where x is the serial port allocated by the ftdi device driver
  • Speed: 115200

Save this configuration and press the Open button to continue.

You will receive a request of login end password. Use these credentials:
