check /etc/uboot-env.conf if the values are ok for your HW (i have no idea and only Cx4p to test).
also you can try "uboot-env" command a bit manually (without param help will be displayed).

this are four steps running during kernel update:

Code:

uboot-env del -i
                uboot-env set < /etc/uboot-env/default.txt
                uboot-env set script boot.scr
                uboot-env set bootdelay 0

it looks like all are failing. Can you try the first step with uppercase I?

Code:

uboot-env del -I
