We failed to enable RTL8723 PCI wifi on TX2.
Tx2 is set to config4 and RTL8723 PCI wifi is connected PEX0 with mini-PCIe.
We enabled TX2 L4t R28.2.1’s RTL8723 driver and got the error as attached.
The pci list is as attached.
Thank you for any advice,
Hi,
Could you firstly confirm if config 4 can work or not? The pci device should be shown in lspci even if it is not working. Also, pex0 should work for all cases since it is definitely a pcie lane…
If you could see it in lspci, then please check if extra firmware is needed for your card.
According to the log, it should need one.
Hi WayneWWW,
Thank you for your support.
The config4 works, and the pci device shows in lspci command. (see attached png file)
We tested two PCI wifi modules (RTL8723 and Intel7260) by enabled wilreless driver in L4T R28.2.1.
When RTL8723 module was connected to Tx2, system hung up.
When Intel 7260 module was connected to Tx2, there is no new wifi endpoint. ( see attached png file)
And error message shows up. (see attached text file)
Does TX2 support RTL8723 PCI wifi module or Intel7260 module?
The RTL8723 PCI wifi module and Intel7260 module work on the other platform.
It’s not clear about extra firmware you mentioned.
Would you address more?
Thank you,
Hi HuiW,
For the RTL8723, the case sounds not good.Are you able to get the UART log when system hangs?
As for i7260, do you install any extra driver for it? If pcie can detect it, then I think you should follow up the instructions from Intel now.
Hi HuiW
I have already to install extra driver for i7260,but it does not working. Do you know which wifi card can match TX2 platform.
Thank you
Please provide the result of dmesg and lspci -vvv.

Hi,
What is the scenario of 20191024_TX2_LOG.txt? RTL8723BE? I don’t see any log reported from rtl8723be.
Also, if the systen hangs, how did you dump the result of lspci -vvv?
Hi WayneWWW
I can go into console mode ctrl+alt+f1
Do you need Dmesg log
Hi aesinfo,
The situation sounds not clear to me.You have 2 issues here
rtl8723 does not work and system get hang.
i7260 does not work.
However, you said you could still go to console mode. It sounds that system does not hang.
What is the exact error here?
Please do share more detail each time you post or attach anything.

It looks like only bluetooth is got blocked and wifi does not.
According to the log, the fw is not loaded. Please contact Realtek for this error.
