SSD Reading Issue after Jetpack Upgrade


I encountered an issue while upgrading from Jetpack 4.6 to 5.1.2.

Previously, with Jetpack 4.6.4, I was able to read both of my SSDs using the m.2 NVMe slot (J11) and the m.2 WiFi/BT slot (J10).
However, after upgrading to Jetpack 5.1.2, I am currently facing an issue. I can only read the SSD via the m.2 NVMe slot, and I am unable to obtain readings from the WiFi slot.

I would greatly appreciate any assistance or guidance you could provide on resolving this matter.

Thank you for your time and consideration

Please share the result of lspci -vvv on your jp4.6.4 result and jp5.1.2 result.

Also, try other kind of nvme drive as cross check to see if only specific kind would hit.

Hi WayneWWW,

Thankyou for your response.

here is the screenshot of the result: (text files is attached below if needed)
Jetpack 4.6.4

Jetpack 5.1.2

I possess three distinct SSDs, and whenever I place any of them in the WiFi slot, they are not detectable (in version 5.1.2).

You need to run it with sudo.

And please attach them as text file but not images…

Hi WayneWWW.

Below are the text files with sudo access:
Jetpack 4.6.4: 464_sudo.txt (14.0 KB)
Jetpack 5.1.2; 512_sudo.txt (8.2 KB)

Best regards,

Just to check, your jetpack5 can detect other wifi card on that slot, right? To prove that slot can actually work.

Hello WayneWWW,

I’ve tested the Intel 8265NGW WiFi/BT module, and here are the results:

In version 5.1.2: Only Bluetooth is functional, and the settings indicate 'no Wi-Fi Adapter Found.'
In version 4.6.4: Both WiFi and Bluetooth are working correctly.

Best regards,

What is the result of lspci ?

Hi WayneWWW,

Below are the the results of lspci:
Jetpack 4.6.4 : 464_WiFiBTCard.txt (13.9 KB)
Jetpack 5.1.2 : 512_WiFiBTCard.txt (8.2 KB)

Best regards,


Intel 8265 card can get detected on our board. Are you sure you are using devkit?

$ lspci
0004:00:00.0 PCI bridge: NVIDIA Corporation Device 1ad1 (rev a1)
0004:01:00.0 Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78)
0005:00:00.0 PCI bridge: NVIDIA Corporation Device 1ad0 (rev a1)
0005:01:00.0 Non-Volatile memory controller: Silicon Motion, Inc. Device 2263 (rev 03)

Hi WayneWWW,

yes I used the original devkit Model:P3518, but still does not work,
i also tried with Leetop’s devkit, Wi-Fi also does not work.

Best regards,

Please check hardware/nvidia/platform/t19x/jakku/kernel-dts/common/tegra194-p3668-common.dtsi

And let this part take effect and see if your card could work in lspci or not.

362 		w-disable1 {
363 			gpio-hog;
364 			output-high;
365 			gpios = <TEGRA194_AON_GPIO(CC, 2) GPIO_ACTIVE_LOW>;
366 			label = "w-disable1";
367 			status = "okay";
368 		};
369 		w-disable2 {
370 			gpio-hog;
371 			output-high;
372 			gpios = <TEGRA194_AON_GPIO(CC, 0) GPIO_ACTIVE_LOW>;
373 			label = "w-disable2";
374 			status = "okay";
375 		};

Hallo WayneWWW.

I believe I have determined that the NVIDIA module(P3688) is malfunctioning/Faulty. (not the devkit)
After trying a different new NVIDIA Module (P3688) on the same devkit and installing Jetpack 5.1.2, I observed that it was able to read the Wi-Fi module.
I am very confused why these PCIe lanes or Wi-Fi no longer work.
