Hi,
In my previous working version of U-boot I used CONFIG_SKIP_RELOCATION but this doesn't seem to work any more.
Any reason why it doesn't work any more ? Is there another way to skip relocation ?
It actually has no sense any more. The current code skips the relocation if, and only if, U-boot is already running at its final destination.
Trying to run U-boot without relocating and without being at the link-time address would not work.
OK, that does make sense.
In my case u-boot is in NOR. What do I need to boot from NOR ?
Is there any example that boots from NOR ?
Below is the config I used about 2-3 month ago. Perhaps anyone has a hint how to make it work with the current relocation code ?

Forgot to mention a few items :
I flash the NOR at address 0x10020000 TEXT_BASE is 0x10020000
I'm about to give up on this code and move back to older code of 2-3 months ago where things worked well.
My feeling is that I miss something very simple, but I'm looking for it for days now and will give up on it by tomorrow and move back to old u-boot code of 2-3 months ago just to continue what I really want to get done (making USB device work).
Best regards, Marcel
