    Hi Hiroyasu,

    In similar sitara device (AM387x), there is no option to save the u-boot environments to EMAC/TFTP/NFS. Even when booting from EMAC, the u-boot environment can be saved in NAND/SPI/SD media. I suspect the same is valid here, for sitara AM335x device.

    Where is your uEnv.txt file located? You can place it in TFTP server and use it when boot from EMAC, but you will not be able to use "saveenv" to change that file. You should change uEnv.txt before booting.
