Probably not. At least I don't know of any port of U-boot for this
board.
BUT: this is off topic here. Please post U-Boot related questions on
the U-Boot mailing list instead.

Similar is not good enough.

Probably, if you know how to use these tools. Sorry, I'm afraid there
is little help for these on tyhe U-Boot list.

Is this the correct address for your board? Did you use the correct
terminal baudrate?

You should be able to. If not, return the tools to the vendor and get
your money back.

No.

No. If the environment is invalid (bad CRC checksum), then a
compiled-in default environment will be used.

Dunno.

Sorry, you need a lot more information about the hardware to give any
usable help - and then it requires a non-negligible amount of work to
come up with the right config data. Don't expect too much from a
mailing list.
