I was very careful, actually.

I told you, several times, and I repeat it here again, for the last
time, promised:

If you want to have an easy start, use a separate device tree. This is
what has been tested all the time, and what is known to be working.

If you go for cuImage, this is completely untested code on TQM8xx, and
you are on your own - this may work, but it is more likely that it
doesn't.

Your choice.

You already updated U-Boot successfully, so there is no need to
continue trying cuImages.  But it's your choice.

It is easier to change the specification to fit the program than vice
versa.
