GW16146 miniPCIe 802.11ah Radio Module

The GW16146 is a miniPCIe form factor 802.11ah radio consisting of:

The GW16146 differs from the Newracom NRC7292 EVK in the following ways:

  • Sits behind a FT232H USB to SPI bridge
  • Uses software polling instead of an interrupt
  • Uses the Silex SX-NEWAH radio containing the NRC7292 but RF tuned for US operation

View the GW16146 Product Page for pricing and specifications

The GW16146 is designed for USA / North America use at 915MHz. For European usage at 868MHz, please contact Gateworks Sales

FT232H USB to SPI bridge

The FT232H features an multi-protocol engine that can be used for UART, JTAG, SPI among perhaps other things.

Gateworks has programmed the USB VID:PID to 0x2beb:0x0146 which binds to the out-of-tree Linux kernel spi-ft232h driver.

When a GW16146 is found on the USB bus a SPI master host controller will be registered with the Linux kernel which you can see in /sys/class/spi_master. Note that various SoC's used for Gateworks boards also have built-in SPI controllers so you will need to look at the directory in /sys/class/spi_master to see what drivers each spi controller is bound to to find the right one.

Examples:

  • show spi master controllers
    ls /sys/class/spi_master/
    # spi1  spi3
    
  • show drivers providing each master:
    ls -l /sys/class/spi_master/
    #total 0
    #lrwxrwxrwx 1 root root 0 Aug 27 17:59 spi1 -> ../../devices/platform/soc@0/soc@0:bus@30800000/30830000.spi/spi_master/spi1
    #lrwxrwxrwx 1 root root 0 Aug 27 17:59 spi3 -> ../../devices/platform/soc@0/soc@0:bus@32c00000/32e50000.usb/ci_hdrc.1/usb2/2-1/2-1.3/2-1.3:1.0/spi-ft232h.0/spi_master/spi3
    
    for i in $(ls /sys/class/spi_master/); do echo $i:$(basename $(readlink /sys/class/spi_master/$i/device)); done
    # spi1:30830000.spi
    # spi3:spi-ft232h.0
    
  • find spi master bound to spi-ft232h:
    for i in $(ls /sys/class/spi_master/); do if [ "$(basename $(readlink /sys/class/spi_master/$i/device))" == "spi-ft232h.0" ]; then echo $i; fi; done
    # spi3
    
  • assign the bus number of the first spi-ft232h bus to a var:
    BUSNO=$(for i in $(ls /sys/class/spi_master/); do if [ "$(basename $(readlink /sys/class/spi_master/$i/device))" == "spi-ft232h.0" ]; then echo $i | sed 's/[^0-9]*//g'; fi; done)
    echo $BUSNO
    #3
    

Note that the SPI bus frequency can range from 450KHz to 30Mhz in 30MHz/n divisions where n is 1 to 65535 thus 30, 15, 10, 7.5, 6, 3.75MHz and so on. Invalid values will round up to the next highest freq. The frequency will be requested from the nrc.ko driver via the hifspeed kernel param (see below)

Building:

  • The driver compiles a single module 'spi-ft232h.ko' and can be built out-of-tree by assigning KDIR to the directory of your kernel:
    KDIR=/usr/src/venice/bsp/linux make
    

NRC7292 kernel driver

The Silex SX-NEWAH module on the GW16146 has a Newracom NRC7292 and thus is mostly supported by Newracom's open-source driver. However, the Newracom driver assumes a SoC GPIO is used for SPI IRQ and in the case of the GW16146 this does not exist. Therefore a SPI polling feature was added to the driver therefore Gateworks has its own nrc7292 driver.

There is a large set of kernel params (which you can see via 'modinfo nrc.ko') but for our purposes the following are needed:

  • fw_name - firmware file from /lib/firmware
  • bd_name - Board data file from /lib/firmware
  • hifspeed - port speed in MHz (recommend 30000000 for 30MHz; available frequencies are 450KHz to 30Mhz in 30MHz/n divisions where n is 1 to 65535 thus 30, 15, 10, 7.5, 6, 3.75MHz and so on. Invalid values will round up to the next highest freq)
  • spi_bus_num - SPI bus number (find this dynamically from /sys/class/spi_master)
  • spi_cs_num - SPI chip select (must be 0 for FTDI USB_SPI bridge)
  • spi_polling_interval - SPI polling interval in ms (recommend 5ms)

The following steps have been condensed into a downloadable script.

You must determine the SPI bus at runtime which can be done via:

BUSNO=$(for i in $(ls /sys/class/spi_master/); do if [ "$(basename $(readlink /sys/class/spi_master/$i/device))" == "spi-ft232h.0" ]; then echo $i | sed 's/[^0-9]*//g'; fi; done)
echo $BUSNO

Now the module can be loaded as such:

modprobe nrc fw_name=nrc7292_cspi.bin bd_name=nrc7292_bd.dat spi_bus_num=$BUSNO spi_polling_interval=5 hifspeed=30000000

After several seconds due to the timing of firmware loading you should see a new wlan device under /sys/class/net. To find the correct wlan interface that is bound to the NRC7292 driver:

WLAN="$(for i in $(ls -d /sys/class/net/wlan* 2>/dev/null); do if [ "$(basename $(readlink $i/device))" == "nrc80211" ]; then basename $i; fi; done)"
echo $WLAN
# wlan0

After bringing up the interface you can perform more configuration on it via the 'cli_app' (see below)

ifconfig $WLAN up

Building:

  • The driver compiles a single module 'nrc.ko' and can be built out-of-tree by assigning KDIR to the directory of your kernel:
    KDIR=/usr/src/venice/bsp/linux make
    
  • kernel requirements: CONFIG_CRYPTO_CCM, CONFIG_CRYPTO_GCM, CONFIG_CRYPTO_SEQIV, CONFIG_CRYPTO_CBC, CONFIG_CRYPTO_CTR, CONFIG_CRYPTO_ECB, CONFIG_CRYPTO_AES

cli_app

There is a 'cli_app' that is part of the driver code which communicates with the driver via the Netlink generic socket family API. Netlink is a Linux kernel interface used for inter-process communication between kernel and userspace similar to unix domain sockets designed for transferring miscellaneous networking information between kernel space and userspace processes. See https://en.wikipedia.org/wiki/Netlink for details.

The cli_app facilitates setting misc details that are not handled via iw. The app can be used in interactive mode by running without args or by sending commands.

    2. Obtain the SPI bus number created by the spi-ft232h driver which has bound to the GW16046 via VID/PID (Note that we save this in the BUSNO env variable which will be used below)
      BUSNO="$(for i in $(ls /sys/class/spi_master/); do if [ "$(basename $(readlink /sys/class/spi_master/$i/device))" == "spi-ft232h.0" ]; then echo $i | sed 's/[^0-9]*//g'; fi; done)"
      echo $BUSNO
      # 3
      
    3. Load the NRC7292 driver providing the SPI bus number from above (we use the BUSNO env var here):
      modprobe nrc fw_name=nrc7292_cspi.bin bd_name=nrc7292_bd.dat spi_bus_num=$BUSNO # spi_polling_interval=5 hifspeed=30000000
      
      • after several seconds you should see a new wlan device under /sys/class/net
    4. obtain the wlan device that is bound to the driver (note it takes several seconds after loading the driver module for the device to get registered due to firmware loading and timing) (Note that we save this in the WLAN env variable which will be used below)
      WLAN="$(for i in $(ls -d /sys/class/net/wlan* 2>/dev/null); do if [ "$(basename $(readlink $i/device))" == "nrc80211" ]; then basename $i; fi; done)"
      echo $WLAN
      # wlan0
      
    5. bring up the interface (required for configuration below)
      ifconfig $WLAN up

Troubleshooting

  1. Ensure the device can be seen on the USB bus:
    # lsusb -d 0x2beb:0x0146
    Bus 001 Device 003: ID 2beb:0146  
    
  2. Ensure the spi_ft232h driver is loaded
    # lsmod | grep ft232
    spi_ft232h             24576  0
    # dmesg | grep ft232
    [    7.555554] usbcore: registered new interface driver spi_ft232h
    
  3. Ensure the spi_ft232h driver has registers a SPI bus:
    # ls -l /sys/class/spi_master/ | grep ft232h
