I have a RTL8822CE wifi/bt pci m.2 module .
PCI can be detected and wifi/bt use properly on Xavier NX (running 4.5.1).
But wifi is not probed in kernel on TX2NX (running 4.6).
PCI can be detected and bt is activated in kernel.
attached files are dmesg log and lspci from NX and TX2NX and data sheet of RTL module.
Is there any modify need to verified on TX2NX? WNFT-237ACN(BT)_datasheet ver.1.4_20200415.pdf (532.9 KB)
it seems the roofs built from l4t doesn’t put rtl8822ce.ko in to "/lib/modules/kernel/driver ".
If i use sdkmanger to flash image ,rtl8822ce.ko is existed.
Maybe it is the problem in my build script.
