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" ;-)
The answer is "NO". You cannot load the _normal_ U-Boot image to RAM and start it. You must prepare a _special_ image which omits all the initializations that are normally included.
This FAQ addresses the situation where people want to load and run their _normal_ images before burning these to flash. And this CANNOT be done like that.
Best regards,
Wolfgang Denk
