While getting acquainted with possible u-Boot development issues, I read FAQ "14.2.1. Can U-Boot be configured such that it can be started in RAM?" and was puzzled to learn that u-Boot cannot run from RAM.

you misread it. the question is for people who have loaded u-boot, and then want to load another copy of u-boot into ram and then execute that directly.

so the question is "can u-boot be *started in ram*" and the answer is "no".

The answer is "yes if you know how to do it" ;-)

normally u-boot is bootstrapped from non-ram storage (via a bootrom, or some bit of code being latched in at a hardcoded address, or some other cpu-specific magic). -mike
