Take the following as the reference:

https://github.com/lentinj/u-boot/blob/master/doc/README.standalone

According to the second link, seems that you have to load and run the application to the 0x0c100000 address for the ARM architecture.

Hope it will be helpful.

Basically, don't forget that Uboot is just a bootloader, not an OS, and it is not meant to run a complicated applications.

Have a great day,
Artur
