uEnv.txt ignored ?

hi,

is it possible, that my uEnv.txt is ignored by the uBoot I am using?
Is there any check to proof this?

Thank you very much in advance for any help!
Best regard,

I think it is possible. I’ve been having some issues with booting on the BeagleBone, and noticed that when I switched to the stock MLO and u-boot.img that the uEnv.txt was being ignored.

I verified that very easily as the uEnv.txt I had previously was pointing to a kernel v3.2.0 and once I rebooted with the new MLO and u-boot.img, I was greeted by a v3.2.28 kernel.

First verify 'uEnv.txt' is actually being used.. Using the serial port
connect, watch your boot process it should say "loading * from
uEnv.txt"..

Then re-verify what ever you 'changed' is actually being used, as the
"uEnv.txt" is just setting user environmental variables.. So if those
variables, you changed or added are not being used, well then they
wouldn't be used..

I was having the same sort of trouble until I realized that there are
a string of environment variables set from
include/configs/am335x_evm.h when you run 'make am335x_evm_defconfig'.
Some of them can override your uEnv.txt stuff unless you set the
exact same variable in uEnv.txt.
