guess it kernel/driver issue The driver does not request the stmmaceth (emac1-25M) clock during probe. Without this clock the MDIO bus does not function on cold boot - PHY ID reads as 0x00000000 and kernel falls back to Generic PHY instead of YT8531. Ethernet does not work until warm reboot.

@JamesCl Sorry, It's ok with 100m, but 1000m also doesn't receive an ip with dhcp. Guess it is a dtb problem or maybe uboot

extraargs=nvme_core.default_ps_max_latency_us=0 pcie_aspm=off pcie_port_pm=off to /boot/armbianEnv.txt fixes nvme detection the temperature is echo "$(( $(cat /sys/class/hwmon/hwmon0/temp1_input) / 1000 )) °C" if you copy the system to nvme and wanna boot with microsd (spi doesn't work for now): 1) it will actually boot but without boot mountpoint 2) mount /boot and /media/mmcboot manually 3) fix fstab
