Have a ls1012a-frdm board. Use kernel-fsl-ls1012a-frdm-20170329175402.itb from SDK v2.0-1703. I use ready file, I didn't build it with yocto. When I boot and config eth0 I can't ping anything. Seems like network subsystem didn't work. I connect board and my host PC to the same switch, on PC I run wireshark and look at network activity. When I start pinging PC from board, I see no activity on wireshark, even no arp request from board. If look at the arp table at the board I see that board can't resolve IP of PC to mac. Before booting linux I download itb file from host PC to board using tftp command of uboot. So the network line is OK. After booting to linux I use the same IP that I use for tftp downloading.
Now what I do step by step.
md5sum kernel-fsl-ls1012a-frdm-20170329175402.itb
b614a6be23070c7e568a11b2c2e52225 kernel-fsl-ls1012a-frdm-20170329175402.itb
Board have some predefined firmware at SPI, after connecting to board via debug usb and reseting board I see next uboot output: https://pastebin.com/raw/kVk8FuCH .
env print: https://pastebin.com/raw/hGuZtcPH
I give command:
tftp 0x96000000 kernel-fsl-ls1012a-frdm-20170329175402.itb
bootm 0x96000000
And here the output: https://pastebin.com/raw/zdmhtgjC
Linux booted at the moment and I use manual configure eth0:

And I try to ping my PC:
