Hi, Unsetting BUILD_DIR solved the problem.
Of course /u-boot-2009.08_build/cpu/leon3/start.S does not exist here. I´ll try to figure out what´s wrong in the Makefile. Thanks.

Stop. The source has a cpu/leon3/start.S file. The Makefile in that directory has $(START): $(START:.o=.S) so that is where the dependency is coming from. Is the file's location correct? Does the file really exist there: ls /u-boot-2009.08_build/cpu/leon3/start.S > I´d like to add that I set "BUILD_DIR=`/u-boot-2009.08_build" and I > am using Gaisler`s Bare Cross Compiler with GCC 3.4.4.

Setting BUILD_DIR to be an absolute path (leading "/") seems odd. <http://www.denx.de/wiki/DULG/UBootConfiguration> says... "By default the build is performed locally and the objects are saved in the source directory. One of the two methods can be used to change this behaviour and build U-Boot to some external directory:" Try building it in the source directory rather than putting the output in a separate directory. There are perennial problems with building into a separate directory (e.g. the $(OBJ) prefix is not prepended to the destination). This is an easy thing to miss or mess up (also easy to fix). Since leon3 is not a heavily used target, I would suspect that is the problem. I would suggest not using BUILD_DIR and see if it works. If it does, update the cpu/leon3/Makefile to look like a more heavily used target CPU, e.g. a PowerPC like the 83xx: <http://git.denx.de/?p=u-boot.git;a=blob;f=cpu/mpc83xx/Makefile;h=15e2c18b13760c25f266a51934659c4fdc845730;hb=HEAD> > > Thanks for your help! > > Best regards, > > Tobias Kraitschy Good luck, gvb _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
