No, you don't have to build it. This would add a rather long coffee pause to your workflow ;) > As the next step I wanted to export PATH and CROSS_COMPILE like it's > decribed on this page: > http://www.denx.de/wiki/view/DULG/ELDKUsage Sorry, but this page does not apply to ELDK 5 anymore. Usage of the new ELDK is not yet up to what it should be, so please bear with me. Inside the installed ELDK you will find a script that sets up the environment as needed. If your installation lives below /opt/eldk-5.0, this will be /opt/eldk-5.0/powerpc/environment-setup-powerpc-linux To only build u-boot, we reall y only need the PATH setting, so for the example here I copy that manually: [dzu@pollux ~]$ export PATH=/opt/eldk-5.0/powerpc/sysroots/i686-oesdk-linux/usr/bin:/opt/eldk-5.0/powerpc/sysroots/i686-oesdk-linux/usr/bin/powerpc-linux:$PATH Now CROSS_COMPILE needs to sync up with the names of the cross toolchain, in our case that is what TARGET_PREFIX is set to in this script. Again I will do this manually: [dzu@pollux ~]$ export CROSS_COMPILE=powerpc-linux- That's as much as we need to compile U-Boot, so let's do that: [dzu@pollux ~]$ wget ftp://ftp.denx.de/pub/u-boot/u-boot-2011.09.tar.bz2 [...] [dzu@pollux dzu]$ tar jxf u-boot-2011.09.tar.bz2 [dzu@pollux dzu]$ cd u-boot-2011.09 [dzu@pollux u-boot-2011.09]$ make Lite5200_LOWBOOT awk '(NF && $1 !~ /^#/) { print $1 ": " $1 "_config; $(MAKE)" }' boards.cfg > .boards.depend Configuring for Lite5200_LOWBOOT - Board: IceCube, Options: SYS_TEXT_BASE=0xFF000000 make make[1]: Entering directory `/tmp/dzu/u-boot-2011.09' Generating include/autoconf.mk cc1: error: Do not use -Os option if --enable-target-optspace is not set.

I forgot to say that we underwent much pain as recent toolchains dropped support for the "-Os" for the Power architecture. A fix for this is only in mainline for a short while and will be included in our 5.1 release due in the next weeks. So for the current ELDK, we need to remove this option: dzu@pollux u-boot-2011.09]$ perl -pi.bak -e 's/^OPTFLAGS=.*$/OPTFLAGS=-O2/' config.mk [Note that we need -O2, compiling without optimization will fail.

No, this is not valid any more. ELDK 5.0 is not a further development of ELDK 4.2 but a "completely different beast under the hoods".
