The thread started with trying to solve the problem
with U-Boot beeing downloaded from Linux and then written
to the flash.

There is NOONE talking to the console after the reboot,
and the assumption is that Linux has not updated the environment.

Based on this: how do you sync the ver and the U-Boot version?

All your proposals are failing, since you assume that there
is a gremlin somehwere which starts toggling RXD.
