Test for device

We are using Intel 7260 wireless device to test PCIE. Check the bus:

$ dmesg | grep -i pcie
[    3.750038] imx6q-pcie 1ffc000.pcie: PCI host bridge to bus 0000:00
[    3.831355] pcieport 0000:00:00.0: Signaling PME through PCIe PME interrupt
[    3.837040] pci 0000:01:00.0: Signaling PME through PCIe PME interrupt
[    3.842274] pcie_pme 0000:00:00.0:pcie01: service driver pcie_pme loaded
[    3.842382] aer 0000:00:00.0:pcie02: service driver aer loaded

Serach for devices:

$ lspci 
The output should look like:<br>
00:00.0 PCI bridge: Device 16c3:abcd (rev 01)
01:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61)

  • Build the kernel and modules.
  • get the firmware firmware. Make sure you get the one match your kernel version. We used iwlwifi-7260-ucode-25.228.9.0.tgz.
  • Remove all modules form your target file system "/lib/modules/*" and install the moduels from your current build
  • Deploy the kernel from your current build.
  • copy the firmware to your target "/lib/firmare" directory.
  • Boot your target.
