R: [U-Boot-Users] can i load u-boot into RAM and jump to it as a test?

before i commit myself to reflashing with u-boot, i'd like to know if it's possible to just load it into RAM and use the current bootloader to jump to it, just to see the menu come up, nothing more.

You can do it, but for starting in ram some changes are needed; for example, you cannot change IMMR or program SRAM controller when you start from RAM.

For testing the personal modification of u-boot in my board, I have a standard starting u-boot in flash (that I never modify when running fine), and every change is made in the same version but compiled for starting in ram; so I can test every change very quickly. For adding command or some functionalities this is good, but you cannot test all the HW init part.
