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.
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?
