[U-Boot] Is it possible to boot the U-boot from the another U-boot from the flash area

Hi All,

I am really curiuos to see if U-boot can boot another version or another Uboot burnt in flash ? Its like having 2 images of U-boot which can boot each other if it is possible can any one of you hint me how I can achive this. I tried to relocate the Uboot and burned on to the flash in 2 different loacation however when I try to do "go <U-boot effective address>" it ends up in TLB error in early stage of flash execution.

Thanks for the Help. Ish
