I press Ctrl+D, but there is no result.

Please help.

Can you share what exactly you do, the exact commands? I will try this on my end.

I have entered your recommended commands in uboot menu:

Please, enter these commands in U-Boot console to fix this issue.

=> env default -f -a
=> saveenv
=> reset

Which exact commands you use to build the rootfs?

At flash-card, I have delete all from rootfs, and copy files and directories from tisdk/build/arago-tmp-external-linaro-toolchain/work/am57xx_evm-linux-gnueabi/core-image-base/1.0-r0/rootfs.

I do the same procedure as you and my board just boots fine. Please, try to boot with different SD card, make sure that files are successfully and completely copied to your SD card.

See my log.
