Ideally this should be in a script "reboot_cmd" which gets executed at every reboot before anything else is executed.
I really don't understand why you make all this so complicated.
I think we agree that all that needs to be done is running a single "saveenv" command once after installation of a new U-Boot image (which is supposed to never to happen in the field anyway).
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.
