[i.MX 8MN DDR4+MCIMX8M-AUD ] How to BT, eth0 enabled

[bryan_hong]

Hello

I must use `fsl-image-af-littlekernel` to boot. If I use imx-image-multimedia, the boot failed at i.MX 8MN DDR4+MCIMX8M-AUD

But, I use `fsl-image-af-littlekernel`, these pulseaudio, pactl, pacmd commands not be included in rootfs.
and eth0 can not be up.
===
root@imx8mnddr4ab2:~# ifconfig eth0 up
[ 15.749082] fec 30be0000.ethernet eth0: Unable to connect to phy
ifconfig: SIOCSIFFLAGS: No such device
===

plz help me

thanks
Bryan
