Enable the Intel AC-8260 module

Hi Community member,

Now we are going to use the external Wi-Fi module(Intel AC-8260 M.2 key module) instead of internal Wi-Fi module on Development kit. But I could not work new wifi module. Could anyone provide advise to us?
Here is the way which I have done.

  1. Edit the ODMDATA value form 0x1090000 to 0x90000 on 2771-0000.conf.common file.

  2. Run the following command.
    sudo ./flash -r -k kernel-dtbs jetson-tx2 mmcblk0p1

  3. Boot the Jetson TX2 and get the kernel

  4. Change the kernel config.
    Enabled(Embeded) the “Generic IEEE 802.11 Networking Stack”
    Enabled(Embeded) the “Intel Wireless WiFi Next Gen AGN -Wireless-N/Advanced-N/Ultimate-N(iwlwifi)”

  5. Compile the kernel and copy the Image file to /boot directory on jetson TX2.

  6. Get the firmware for AC-9260 via “apt-get install linux-firmware”

  7. Reboot the Jetson TX2.

If you have any question, please let me know.
Best regards.


If your device is detected by M.2 key, it should be listed in lspci (it is pcie based, right?).

Also, please share your full dmesg with us. Thanks.


Thank you for your response.
I could be recognized the Wi-Fi on M.2 key on development kit by following method.
1.Edit the ODMDATA value form 0x1090000 to 0x90000 on 2771-0000.conf.common file.
2.Flash the standard Jetpack 3.2.1 by command.
sudo ./flash jetson-tx2 mmcblk0p1

So, it seems that it could program the ODMDATA at first jetpack flashing but it could not update the ODMDATA after once flashing the jetpack.
Do you know the way to update the ODMDATA after flashing the jetpack?

Also, developmentkit can recognized this module by lspci but it could not be enabled the wifi even though used the kernel which enabled the Intel wifi like my previous post.

Best regards.


“So, it seems that it could program the ODMDATA at first jetpack flashing but it could not update the ODMDATA after once flashing the jetpack.”

Actually, I am not sure what is this statement talking about.

It is necessary to reflash device if you want to update odmdata.


I apologize for your confusion. Now current status is that our development board could be recognized the wifi module with using the lspci command by changing the programming method. Here is the way to do on our side.

Successes Process

  1. Edit the ODMDATA value form 0x1090000 to 0x90000 on 2771-0000.conf.common file.
  2. Run the command of “sudo ./flash jetson-tx2 mmcblk0p1”

Failed Process

  1. Flash the jetpack by intell package.
  2. Edit the ODMDATA value form 0x1090000 to 0x90000 on 2771-0000.conf.common file.
  3. Run the command of “sudo ./flash -r -k kernel-dtbs jetson-tx2 mmcblk0p1”
    Note: At this time, ODMDATA was not updated.

So, would you please teach me the way to update the ODMDATA after installing the jetpack?
I have already known that we need to flash the device in order to update ODMDATA.

Also our development was recognized this module, but it cannot use the wifi module.
Would you please give me advice?

If you have any questions, please let me know.
Best regards.


ODMdata is not part of DTB so “-k kernel-dtbs” is not needed when updating.

Is there any driver working with your device? Are you sure this driver is existing in our kernel?

Thank you for your response. I got it. If we update the ODMDATA, we should use the “./flash -r jetson-tx2 mmcblk0p1”.

Yes, I got it by using the “apt-get install linux-firmware” and found the wifi dirver named as “iwlwifi-9260-th-b0-jf-b0-3x.ucode” at “/lib/firmware” directory.

Best regards.


That is a firmware but not a kernel module/driver. Take our native wifi for example, command “lsmod” would show brcm driver module and /lib/firmare directory also has another firmware for brcm phy.

Please make sure you’ve installed the driver.


Thank you for your response.
Now I confirm the driver for AC-9260, it seems that the iwlwifi driver is old because there is not contains the firmware for AC-9260. Here is the log file when called the modinfo iwlwifi.

Do you know the way to update this module?

Best regards.

Please check with Intel for newer driver. Thanks.

FYI, drivers and firmware are usually downloaded separately (though quite often changing a driver causes a need to change firmware).

Hi All,

Thank you fro your advises.
I could work the AC-8260 on my development board.

Best regards.
