I recently installed Jetpack 4.4 from a Jetson Xavier NX SOM with a B01 Nano Carrier and everything appears except the wifi does not want to enable, the bluetooth appears to be enabled on the same card. The driver appears to load but I am unable to enable the radio on the Intel 8265 (This previously worked on the a Jetson Nano running on an A01 carrier).

Hi zanyfool,
I found this error too, and the /var/log/syslog shows rfkill blocked the wlan0, but I haven’t found solution now.

This issue is duplicated with this one. We are still checking.
Hi,
Intel Dual Band Wireless-AC 8265 module did not work on NX by default, as we test it. ( the module works well on Nano.)
Does NX (Jetpack 4.4) support Intel Dual Band Wireless-AC 8265?
If yes, what should we do to make it work?
If not, is there any patch or document to make it work?
Thank you,
Could you guys also share your full dmesg?
Hi WayneWWW,
I have uploaded Xaveir NX with Intel 8265 WIFI/BT module dmesg log.
nx.intel8265.wifi.failed.0504.log (62.4 KB)
Thanks for sharing. I can confirm it is duplicated with the link I posted.
Will update once we find the cause.
Please try this patch

The patch didn’t work for me. It is possible I didn’t apply it correctly.
I did try the following and was able to enable the wifi.
I modified (1) removed from common/tegra194-fixed-regulator-p3668.dtsi:
gpio = <&tegra_aon_gpio TEGRA194_AON_GPIO(CC, 2) GPIO_ACTIVE_LOW>;
from:
common/tegra194-fixed-regulator-p3668.dtsi
And (2) modified:
hardware/nvidia/platform/t19x/common/kernel-dts/t19x-common-platforms to replace wifi-enable with:
gpio@c2f0000 {
wifi-disable {
gpio-hog;
output-low;
gpios = <TEGRA194_AON_GPIO(CC, 2) 0>;
label = "wifi-disable";
status = "okay";
};
};
After these changes, the wifi card was enabled at boot.
Hi zanyfool ,
I don’t think you need to remove the original wifi-enable pin. As you can see, they are different gpio pins.
Also, could you try this patch too?

I have tried your last patch, it doesn’t work. I modified as below and Intel8265 works fine.

Hi Ciya.Jiang,
Is it necessary to set below part? I think the second part you’ve done in tegra194-p3668-common.dtsi should work.
Could you help verify?

Hi WayneWWW,
This part is needed, but “enable-active-low;” is not needed.

Hi Ciya.Jiang ,
It seems
gpio = <&tegra_aon_gpio TEGRA194_AON_GPIO(CC, 2) GPIO_ACTIVE_LOW>;
and
gpios = <TEGRA194_AON_GPIO(CC, 2) 0>;
are a conflict. Because the “0” in the second case is set it back to GPIO_ACTIVE_HIGH again.
Anyway, I will check it.
At least I can confirm the solution works . I made the patch with both parts (and with enable-active-low;) and it works fine for me . Thank you so much for the solutions. you made my day. :)

Hi,
Also want to ask if anyone has bluetooth issue here after apply the patch above?
