ethernet@ff0c0000 Waiting for PHY auto negotiation to complete...... done

where is setting u-boot env variable? when it occurs warning bad crc in booting.
I'd wrote BOOT.BIN file in NAND flash and if booting my zyqnmp board, it occurs warring bad CRC in NAND flash. so u-boot was setting default env.

and then u-boot is displayed "ethernet@ff0c0000 Waiting for PHY auto negotiation to complete...... done" message.

After entering uoot mode in such a state, I input saveenv command and reboot, bad crc does not occur. also u-boot is not diplayed "ethernet@ff0c0000 Waiting for PHY auto negotiation to complete...... done" message.

in platform-top.h, I'd written "autoload=yes".
why after NAND writes, it occurs bad CRC in first booting? and why is it not include autoload=yes config?
where is the default u-boot environment variable?

 

after NAND write and boot zynqmp board.
