Re: [U-Boot-Users] Relocatable U-Boot

A handful of projects I have worked on use multiple copies of u-boot stored in different locations of flash and a small assembly stub determines which to boot. Currently, to do that u-boot has to be compiled two different times with different settings to accommodate the different base addresses.

Is there a way to use a single build of u-boot which can be placed at two different addresses in flash? That seems to me that it would be a useful general feature.

If you copy your U-Boot to RAM, you can have multiple U-Boots each linked to the same location. You need a small utility which runs before U-Boot which determines which version to use.
