How to enable ethernet(dhcp) on lx2160

[m_kei]

I am booting TinyLinux using SD boot with lx2160ardb_rev2.

However, eth0 cannot be enabled on this Linux.
"ifconfig -a" shows only "lo" and "sit0" (disabled at startup).
Since u-boot is able to do ethernet communication, I am assuming that Linux either does not have a driver or needs to be configured in some way.

What do you need?

Please apply DPL file before booting up Linux.

=> sf read 0x80d00000 0xd00000 0x100000
device 0 offset 0xd00000, size 0x100000
SF: 1048576 bytes @ 0xd00000 Read: OK
=> fsl_mc lazyapply dpl 0x80d00000
=> tftp 0xa0000000 b25805/lx2160/lsdk2108_yocto_tiny_LS_arm64.itb

=> bootm 0xa0000000#lx2160ardb

Please refer to the following log in Linux.

As a follow-up report, when I connected an intel LAN card on hand to PCIe as a test, the LAN card was recognized as eth0 and worked fine with DHCP.

However, I still need an answer because it has to be the Ethernet port on the lx2160 board.

I forgot to mention that I am using LSDK-21.08 mkfw installed using flex-installer.
