==WiFi usage==
 +
On PPS, WiFi/Libertas driver usage is a little bit different than on other platforms. Here are the things to know:
 +
 
 +
===Drivers setup===
 +
You have to install Libertas SDIO and MMC drivers as modules to make Wi2Wi chipset work correctly on PPS (done by default):
 +
<pre class="host">
 +
$ make linux-menuconfig
 +
</pre>
 +
 
 +
<pre class="config">

 +
        <M>  MMC block device driver
 +
</pre>
 +
 
 +
===Initializing the connection===
 +
Before creating the WiFi connection, you must load the Libertas SDIO and the MMC modules:
 +
<pre class="apf">
 +
# sh /usr/local/pps/scripts/reset_wi2wi.sh
 +
 
 +
# modprobe mxcmmc
 +

 +

 +
</pre>
 +
 
 +
Then all informations on [[Libertas_driver]] page apply.
 +
 
 +
===Shutdown WiFi interface===
 +
You have to unload the MMC driver along with the Libertas SDIO if you want to completely shutdown the WiFi interface:
 +
<pre class="apf">
 +
# ifconfig eth1 down
 +
# rmmod mxcmmc
 +
# rmmod libertas_sdio
 +
</pre>
 +
 
 +
===Reset Wi2Wi===
 +
To reset the chipset, you have to toggle the Wi2Wi ''RESET'' GPIO (PE11), by calling this script:
 +
<pre class="apf">
 +
# sh /usr/local/pps/scripts/reset_wi2wi.sh
 +
</pre>
 +
 
 +
==Test scripts==
 +
You can find test scripts in PPS' filesystem to help you to test the PPS' functionalities.
 +
They are located in the directory ''/usr/local/pps/scripts'' but you can run them from any directory.

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

Resources

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.


Build informations

The following steps have to be performed to build PPS:

Armadeus 5.0 and later: 

# make pps_defconfig
# wget -Ppatches/linux/2.6.29 http://www.armadeus.com/_downloads/apf27_PPS/software_patches/501-pps-armadeus-fix_fxl4_bug.patch
# make

Armadeus 4.1: 

# make pps_defconfig
# wget -Ppatches/linux/2.6.29 http://www.armadeus.com/_downloads/apf27_PPS/software_patches/501-pps-armadeus-fix_fxl4_bug.patch
# wget -Ppatches/u-boot/1.3.4 http://www.armadeus.com/_downloads/apf27_PPS/software_patches/360-pps-apf27.patch
# make


Armadeus 4.0 and earlier: 

# make pps_defconfig
# wget -Pbuildroot/target/device/armadeus/linux/kernel-patches/2.6.29 http://www.armadeus.com/_downloads/apf27_PPS/software_patches/501-pps-armadeus-fix_fxl4_bug.patch
# wget -Pbuildroot/target/u-boot http://www.armadeus.com/_downloads/apf27_PPS/software_patches/u-boot-1.3.4-500-pps-apf27.patch
# make

SSH terminal

The APF27 PPS filesystem is configured to enable SSH connection from a host computer. It allows you to access a system terminal through the default Ethernet port (the one aside USB Host connector).

  • 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 i.MX27. The signals are compatible with a the RS-232 standard (-12V/+12V) so no level translator is required when connecting it to your Host PC

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

WiFi usage

On PPS, WiFi/Libertas driver usage is a little bit different than on other platforms. Here are the things to know:

Drivers setup

You have to install Libertas SDIO and MMC drivers as modules to make Wi2Wi chipset work correctly on PPS (done by default): 

$ make linux-menuconfig

Device drivers  --->
    [*] Network device support  --->
        Wireless LAN  --->
            [*] Wireless LAN (IEEE 802.11)
            <M>   Marvell 8xxx Libertas WLAN driver support
            < >     Marvell Livertas 8388 USB 802.11b/g cards
            <M>     Marvell Libertas 8385 and 8686 SDIO 802.11b/g cards
    <M> MMC/SD/SDIO card support  --->
              *** MMC/SD/SDIO Card Drivers ***
        <M>   MMC block device driver

Initializing the connection

Before creating the WiFi connection, you must load the Libertas SDIO and the MMC modules: 

# sh /usr/local/pps/scripts/reset_wi2wi.sh

# modprobe mxcmmc
i.MX SDHC driver
mmc0: new SDIO card at address 0001

# modprobe libertas_sdio
lib80211: common routines for IEEE802.11 drivers
libertas_sdio: Libertas SDIO driver
libertas_sdio: Copyright Pierre Ossman
libertas_sdio mmc0:0001:1: firmware: requesting sd8686_helper.bin
libertas_sdio mmc0:0001:1: firmware: requesting sd8686.bin
libertas: 00:19:88:11:6b:d8, fw 9.70.3p36, cap 0x00000303
eth1 (libertas_sdio): not using net_device_ops yet
libertas: PREP_CMD: command 0x00a3 failed: 2
libertas: PREP_CMD: command 0x00a3 failed: 2
libertas: eth1: Marvell WLAN 802.11 adapter

Then all informations on Libertas_driver page apply.

Shutdown WiFi interface

You have to unload the MMC driver along with the Libertas SDIO if you want to completely shutdown the WiFi interface: 

# ifconfig eth1 down
# rmmod mxcmmc
# rmmod libertas_sdio
