Hi,

From which device are you trying to boot u-boot.
Is it emmc or the sdhc card??

From your console output:

reading uEnv.txt
473 bytes read in 4 ms (115.2 KiB/s)
Loaded env from uEnv.txt
Importing environment from mmc0 …
" (type: i)lags type check failure for “ipaddr” <= "192.168.7.3

Your settings seemed to be getting overwritten by other settings (could be in the other bootable device).

You could probably try the following:

1.Stop the u-boot boot process at the count down .
2.At the u-boot shell, create new or update env variables with your desired values.
3.Save these environment variables.
4.Restart the board.
5.Linux could be loaded through NFS boot.

Regards,

Adarsh.
