[U-Boot-Users] u-boot.lds

[Charles Krinke]

I am trying to understand more of u-boot.lds with BUILD_DIR defined. This has to do with the fact that I need a second .lds file for a small program that needs to be run from the reset vector in both an 8241 & 8541 before u-boot starts.
 
I can see BUILD_DIR in u-boot/Makefile and the resulting obj := $(OBJTREE) if BUILD_DIR is defined.
 
My issue is that u-boot.lds works fine with BUILD_DIR defined or not. But my second .lds, call it microStart.lds works without BUILD_DIR defined, but not with BUILD_DIR defined.
 
It cannot find the microStart.o defined in cpu/mpc824x/microStart.o if BUILD_DIR is defined, but finds it just fine it BUILD_DIR is not defined. 
 
I can see in u-boot that $obj is not prefixed to the linker objects and wonder how this part of automagic works so I can use the same notion with my microStart.lds.
