Failed to use Wifi module on NX

after applying the first patch with

./flash.sh -r -k kernel-dtb jetson-xavier-nx-devkit-emmc mmcblk0p1

the difference seems to be

diff /home/nvidia/extracted.dts /home/nvidia/extracted.dts.2 
4195c4195
< 			pmc-reset-reason = <0x0>;

> 			pmc-reset-reason = <0x2d>;

the regulator being updated seem to be p3509_vdd_usb2_5v regulator@114

Hi,

We have a quick and simple solution that may work. Please go to

/hardware/nvidia/platform/t19x/jakku/kernel-dts/common$ vim tegra194-p3668-common.dtsi

and remove “vbus-supply = <&p3509_vdd_usb2_5v>;”

Thank you for pointing out!
it turned out that Intel wifi card inserted into M.2 Intel AX would prevent CSI sensors from functioning; when AX gets detached video sensor will work again.
I shall try your suggestion above though

Hi WanyneWWW,

Sorry. I could not find t19x/jakku-dts / common/ tegra194-p3668-0001-a00-common.dtsi

I did remove vbus-supply = <&p3509_vdd_usb2_5v> in common/tegra194-p3668-common.dtsi in previous patch.

Thank you,

Hi Andrey1984,

What is M.w AX here?

Hi HuiW,

You are right. I correct the path.

Could you

  1. Remove vbus-supply = <&p3509_vdd_usb2_5v> in common/tegra194-p3668-common.dtsi

and
2. add below

Hi WayneWWW,

Add previous patch or not? or just add “wifi-disable?”

Thank you,

Hi HuiW,

I just received ac8265 today and verified below patch would work. Please help verify.
If this does not work, please add wifi_disable as comment#35. No need to check any previous patches anymore and just apply either this one or comment#35. What we are doing is simple, just put the Pin CC2 to low.

Hi WayneWWW,

Thank you for your great support.
The new patch works.

I tested the patch with wifi-disable.

Sorry for not getting the result promptly, due to my NX was occupied by other test.

Thank you,

I’m using NX (production module) in Nano B01 carrier board and the intel 8265/8275 WiFi board - as above it shows up in ‘lspci’ but ‘rfkill list’ says “Hard blocked: yes” and it isn’t working. This is just a basic installation from JetPack 4.4. DP (no compilation from source). How do I apply the fix mentioned in this situation please?

Please download the kernel source from dlc and follow the L4T development guide to rebuild the kernel with patched.

Thanks - I’ve tried following these instructions several times but never had a positive outcome. Having built the modified kernel successfully I believe, I suspect that SDK Manager is still transferring the original one onto the NX, is there any more guidance available please on how to apply the modified kernel?
Presumably this will be fixed in the full release of JetPack 4.4 due in “June” - is a more specific date known for this?

Hi,

I guess you are new to jetson platform, so better reading this page.

https://elinux.org/Jetson/General_debug

After you build the kernel image, you have to copy it to Linux_for_Tegra/kernel and use the flash.sh to flash.

Do not use sdkmanager anymore because it might download a kernel image from server again and overwrite your work.

For me, I only use sdkmanager once to download the Linux_for_Tegra and never use it anymore unless I want a clean package.

what are the odds that https://www.mouser.com/ProductDetail/Intel/AX201NGWGNV will work on NX +nano B01 carrier board?
is it highly likely? somewhat likely? unknown? somewhat not likely? not likely?

The Intel 8265NGW works with Nano, so I guess it will work with NX as well. For the model you have linked you will probably end up with missing driver support as it seems to be quite new - unless you know how compile the kernel module yourself: https://www.intel.com/content/www/us/en/support/articles/000005511/network-and-i-o/wireless-networking.html

Put the full patch that could resolve this issue that 8265 fails to get detect.

I can confirm the patch above fixed the issue for me… Will this patch be included in upcoming L4T?

Yes, it is merged to codebase and will be in next release.
