Hi Nvidia Team,

I have Orin Nx 16gb SOM on Orin nano developer kit.
Does orin supports AW-XM458MA-PUR module based on nxp88w9098 chip on pcie?

The AW-XM458MA-PUR module is connected on M.2 KEY E (pcie c1@14100000)of orin nano kit and i haven’t made any changes to firmware.
on command like “lspci” it fails to detect the module and on dmesg below error is displayed

[ 8.429910] tegra194-pcie 14100000.pcie: Phy link never came up

I have also tested AW-CB375NF module which is based on realtek’s RTL8822ce chip, it works fine.
My requirement is wifi with 802.11ax.

Thanks

Try to rescan the pcie device and see if the link would be up or not.

Hi @WayneWWW,

Thanks for the reply.

I have rescanned it but still not getting detected.

I also have one imx8 kit,on imx8’s lspci:
root@imx8mqwave:~# lspci
00:00.0 PCI bridge: Synopsys, Inc. DWC_usb3 (rev 01)
01:00.0 Ethernet controller: Marvell Technology Group Ltd. Device 2b43 (rev 03)
01:00.1 Ethernet controller: Marvell Technology Group Ltd. Device 2b44 (rev 03)

The device shows up as Marvell’s Ethernet controller.
I have tried with multiple modules to check if its faulty or not.

Do i need to change something from devicetree?
Could this be a power sequence issue?

Let me know how can i debug it.

Thanks

HI,

I don’t quite understand what happened here. Why you have another device on your C1?

Hi,

I have used AW-CB375NF just to check if c1 is working or not, my main usecase is 802.11ax so i am using AW-XM458MA-PUR.

It is mostly likely your wifi card requires specific gpio to be set ON to enable that card. That needs to check with the card vendor.

or we have this check list.

But I think it is mostly likely the GPIO issue.

Hi @WayneWWW ,

I will check it and let you know.

Thanks
