Description

PPS is an Armadeus System's baseboard for the APF27 module. It can be used to implement and securize network applications such as routers and gateways.

Front side, you can see dual Ethernet, USB 2.0 Host & OTG, WiFi Antenna, extension connector footprint and power supply
Back side, with an APF27 module plugged-in

Software features

There are some network applications/features that are preselected in the PPS baseboard default configuration:

Note Note: You can also use the PPS test scripts located in /usr/local/pps/scripts on the system to test some software functionalities.


SSH terminal

The APF27 PPS filesystem is configured to enable SSH connection from a host computer. It allows you to access a command terminal of the system through the Ethernet ports.

  • The default connection informations are:
    • IP address: 192.168.0.10
    • Login: guest
    • Password: armadeus
  • Then you can connect to your system by running the following command on your host:
 $ ssh guest@192.168.0.10

Debug / Development interface

In order to gain access to the serial port of the APF27 (U-Boot & Linux console), a small adapter cable has to be done. A standard 2.54mm pin header connector (J5) allows accessing the TX and RX debug lines of the iMX27. The signals are compatible with a the RS232 standard so no level translator is required.

The pinout is described in the datasheet and summarized here:

  • pin 1 (square pad): not connected
  • pin 2: TX line (processor side)
  • pin 3: RX line (processor side)
  • pin 4: GND
J5 pin 1
DB9 connection like on APF27Dev (requires Null-Modem cable)
DB9 connection for direct USB<->Serial adapter usage
