Ah, okay. Then maybe you can keep the pcduino name for the defconfig
and the board directory, assuming that it refers to the v1.

Leave the environment partition unitialized. U-Boot will detect that
there is no valid environment, and will automatically fall back to its
built-in default environment.

By "principle", we don't add additional userspace packages to
defconfig. In addition:

 1/ Your defconfig enables WiFi support, so transferring files over
    serial port doesn't seem very useful.

 2/ Busybox has a "rx" applet that replaces the corresponding program
    from lrzsz.

Thanks!
