Hello there,

i have a device based on BF537-stamp here running uClinux 2010RC1 and i want to update.

The ADI Blackfin homepage provided information, that BF5xx is now supported by buildroot project, too. So i decided to test it - without any luck.


The steps (as described in

First i cloned buildroot from GIT:

     > git clone git://; cd buildroot

     > git checkout -b 2012R2 remotes/origin/2012R2

     > git submodule update --init

Then the subdir linux/linux-2.6.x did not exist. Suppose its linux/linux-kernel now.

After changing all subdirectories to 2012R2 ive downloaded toolchain and set bin directories to my $PATH.

Then i run

     > make bf537-stamp_defconfig


     > make


Result was, "gdbserver configure script detected that gcc can not generate executeables". config.log said

as: unrecognized option '-mcpu=bf537'


So i tried toolchain snapshot .

With that the build (make clean; make) failed on busybox-1.20.2 with the message

     coreutils/id.c:69:2: Fehler: #error "Sorry, you need at least uClibc version 0.9.30 for id applet to build"

     coreutils/id.c: In function ‘get_groups’:

     coreutils/id.c:131: warning: implicit declaration of function ‘getgrouplist’


Google told me, that bug was fixed in 2010... or maybe not? I played arround with some other buidroot trees, toolchains and even older busybox versions without any advancement.


What am i doing wrong?
