Sterling 60 on Ubuntu PC

This tutorial shows how to install drivers and firmware for a Sterling 60 module on a Ubuntu PC.


  • Ubuntu PC
  • Any variant of the Sterling 60 that will interface to the PC


To install drivers and firmware for a Sterling 60 on Ubuntu, first check the kernel version of Ubuntu is compatible with the Sterling 60 driver. Check by going to the Sterling 60 release github and read the release notes CS-RN-ST60-laird-<version>.pdf.

Sterling 60 GitHub:

Depending on the version of Ubuntu the kernel may need downgraded.


Update system and install tools:

# ensure your system is up to date
sudo apt update
sudo apt upgrade

# install software tools needed
sudo apt install make bison flex

Note: ensure any new kernel installed by updating is compatible with the Sterling 60 driver.


This tutorial assumes hardware is interfaced to the PC correctly. Any of Laird’s Sterling 60 DVK’s with USB support work well due to the easy of the USB interface.

The hardware used will determine the firmware used in the next section.


Backports and Firmware

Download backports and the firmware that is specific to the Sterling 60 hardware to be used.

Backports file is labeled: backports-laird-<version>.tar.bz2

Firmware file will be based on hardware type used. For example a USB Wifi and USB Bluetooth variant will use file labeled: laird-sterling60-firmware-usb-usb-<version>.tar.bz2.

# Extract firmware 
sudo tar xvf laird-sterling60-firmware-usb-usb-<version>.tar.bz2 -C /

# Extract driver
tar xvf backports-laird-<version>.tar.bz2

cd laird-backport-<version>

make defconfig-sterling60


sudo make install


To prevent the Marvell driver from loading and interfering with the Sterling 60, black list the following by editing /etc/modprobe.d/blacklist.conf and adding the following lines:

$ sudo iv /etc/modprobe.d/blacklist.conf

# Prevent the Marvell driver from loading for the Laird ST60 module
blacklist mwifiex_pcie
blacklist mwifiex_usb
blacklist mwifiex_sdio


Check dmesg for backports and firmware loading.

Kernel Lockdown

If the kernel module fails to load and the following “kernel_lockdown.7” shows up in dmesg then the kernel is in lockdown and easiest way around this is to disable secure boot in the PC BIOS.
